By offering modular, flexible training on a range of open mapping tools such as OpenStreetMap (OSM), iD Editor, JOSM, Tasking Manager, MapRoulette, StreetComplete, and KoboToolbox\u2014this curriculum enables young people to become not just contributors, but local mapping leaders, driving change within their own communities.\nThe courses emphasizes experiential learning, community engagement, and leadership development. Beginning with an introduction to open mapping and the Humanitarian OpenStreetMap Team (HOT), learners explore the ecosystem of Open Mapping Hubs and understand how open mapping contributes to humanitarian response, sustainable development, and climate action. Structured in progressive modules, the curriculum takes learners from beginner-friendly tools like iD Editor and mobile mapping apps, to advanced techniques in field data collection, validation, and AI-assisted mapping.\nAt the heart of this initiative is the principle of Learning to create impact by taking on leadership roles within their communities, guiding locally-driven mapping efforts that address real challenges and reflect community priorities. Learners are encouraged to work with local communities to identify shared challenges such as access to healthcare, disaster preparedness, or transportation planning and to map these priorities using the tools introduced in the course. This ensures that data generated through mapping reflects real, lived experiences and supports effective local decision-making.\nProject-based learning units guide youth to apply their new skills in mapping initiatives that respond directly to community needs. By learning to plan and manage field mapping campaigns, use offline tools in low-connectivity settings, and support collaborative workflows via Tasking Manager and MapRoulette, learners gain practical experience aligned with real-world humanitarian and development scenarios.\nModules on tools like Mapillary and Mapswipe also provide inclusive, low-barrier entry points for those who may not be able to engage in traditional editing but still want to contribute meaningfully to data improvement.\nThroughout the pathway, youth are encouraged to take on peer-mentorship and training roles within their communities, ultimately becoming open mapping trainers. A dedicated unit on training facilitation and leadership development supports this goal. Learners are introduced to techniques for guiding local mapping sessions, supporting quality control, and mentoring new contributors. This leadership aspect not only reinforces technical skills but also fosters soft skills in communication, planning, and community engagement.\nBy the end of the courses, participants will have:\nGained practical proficiency in open mapping tools gain valuable experience for open mapping mapping skills and experience and leverage them in the development of their professional and civic lives.\n\n\nLearned to plan, manage, and evaluate field data collection activities;\n\n\nUnderstood how to align mapping initiatives with humanitarian, development, and climate goals;\n\n\nEngaged with local communities to ensure that mapping reflects their lived realities;\n\n\nGrown into local leaders capable of training others and sustaining community-based open mapping efforts.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "M7PJ3G", "name": "Rebecca Chandiru", "avatar": "https://pretalx.com/media/avatars/M7PJ3G_I1KHAON.webp", "biography": "I am a happy, people-centered person with a passion for maps and the power of open geospatial data to drive meaningful change.

In Nigeria's Middle Belt region, particularly Plateau State, intensified environmental degradation and conflict have forced thousands of rural farmers to abandon ancestral homelands, resettle in marginal lands, and practice unsustainable land use. These movements go unrecorded, making communities invisible to plan for infrastructure, humanitarian distribution, or climate change adaptation. This study presents a community-led agroecological mapping project that employs OpenStreetMap (OSM) and participatory GIS to map land use, identify restoration opportunities, and advocate for the concerns of displaced farming communities in Bassa and Riyom LGAs of Plateau State.\n\nThe general aim of this research was to integrate open geospatial technology and local knowledge in scaling up climate-resilient agricultural practices and improving marginalised rural citizens' visibility within formal development and planning processes. Under a youth-led community mapping process supported by Kitron Green Initiatives (KGI), over 30 young mappers were trained and mobilised in collecting data on degraded lands, existing farmlands, agroforestry fields, water points, and climatic hazards. Using Field Papers, OpenDataKit (ODK), iD Editor, and QGIS, the data was validated with the community and uploaded to OpenStreetMap. The mapping project also incorporated women farmer groups, traditional leaders, as well as displaced persons to ensure inclusivity and contextual relevance of mapped features.\n\nMethodologically, the research employed a mixed-methods participatory research design. Baseline surveys were initially conducted using qualitative tools\u2014focus group discussions, community transect walks, and semi-structured interviews\u2014to attain a deeper understanding of the lived experience of land use change and food insecurity. This was complemented by hands-on mapping using mobile and satellite-assisted data capture. Data quality was assured through iterative feedback loops with local stakeholders and peer review with members of the YouthMappers chapter of the University of Jos.\n\nIt mapped a total of 19,200 hectares across five displacement-prone villages and detected 267 points of interest related to sustainable agriculture and community resilience. These included organic farms, community storage silos, animal pens, degraded gullies, and informal settlements. The resulting OSM datasets were converted into dynamic story maps, printed community atlases, and open-access web dashboards for stakeholders including the local government, NGOs, and research institutions. Additionally, the project used a digital agro-ecological vulnerability index based on mapped features, local climatic trends, and farmer interviews\u2014guiding focused interventions such as tree planting, drip irrigation, and composting workshops.\n\nThe findings show that participatory open mapping not only improves data coverage in otherwise \"invisible\" rural areas but also builds agency and digital literacy among community members. Young people and women, who were previously excluded from decision-making, gained valuable skills in geospatial technologies and were able to identify previously unrecognized resources and hazards in their locality. Mapping products were also used in a municipal government climate roundtable to advocate for inclusive budgeting and farmer support. Significantly, integrating OSM data into post-displacement planning allowed humanitarian organizations to better map aid delivery to evolving community structures and risk zones.\n\nAcademically, the project contributes to nascent research on community-driven cartography, climate resilience, and data justice in geospatial science. The project demonstrates how the combination of high-resolution open-source mapping technologies and participatory action research can expose spatial inequalities and enable bottom-up climate adaptation. Furthermore, the project confirms that community data\u2014when digitized and mapped\u2014can be powerful evidence for humanitarian response and development planning. The model has replicable potential for other conflict-displaced or climate-stressed agricultural zones in sub-Saharan Africa.\n\nThe practical implications are numerous. For OSM communities, the project illustrates how intentional inclusion of displaced and marginalized communities can strengthen the mapping ecosystem and expand use cases beyond urban-focused projects. For scholars, it offers an empirically tested model for the integration of open data in climate resilience planning, particularly in resource-constrained settings. For government and NGOs, it provides a low-cost, scalable example of bottom-up geospatial data capture that can fill holes in national land-use and cadastral systems.\n\nReproducibility of the research is ensured through the publication of the complete mapping dataset on OSM under the Open Database License (ODbL), with supporting materials\u2014like training manuals, map CSS stylesheets, and dashboard templates\u2014published on GitHub under a Creative Commons Attribution-ShareAlike license. Mapping forms and backend ODK configurations are also shared to facilitate replication in similar settings.\n\nLastly, this study bridges the gap between geospatial science and community development, employing OSM as an empowering, documenting, and planning tool. The study highlights the role of open mapping in building agroecological resilience and enhancing the visibility of the hidden communities, who are typically marginalized by traditional mapping processes. Through the use of participatory methods and open technologies, the project amplifies voice, increases preparedness, and co-produces knowledge that is both locally embedded and globally reproducible. This paper encourages more collaboration between universities, grassroots movements, and the OSM community to continue to explore the nexus of open geodata, climate justice, and rural livelihoods in Africa.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "WGFN3L", "name": "Kitgak Simon", "avatar": null, "biography": "Kitgak Simon is a climate resilience researcher and renewable energy advocate with a background in Electrical and Electronics Engineering.

Standard static routing methods, even those leveraging regularly updated OpenStreetMap (OSM) data, often fail to quickly adapt when a critical bridge collapses overnight or a newly flooded road blocks previously safe routes. Thus, lacking the flexibility to integrate rapidly evolving, mission-critical information from humanitarian organizations and local communities. Our approach addresses this gap by dynamically incorporating real-time, external operational data directly into mobility analysis.\n\nOpenStreetMap provides a foundational role in disaster response, empowering local and remote volunteers to rapidly update map features like road accessibility, infrastructure status, and community resources. Active OSM mapping efforts, such as those coordinated by the Humanitarian OpenStreetMap Team (HOT), continuously enhance the accuracy and timeliness of geographic information available to humanitarian responders. Community-led mapping initiatives ensure that routes, landmarks, and hazard areas are promptly updated, directly benefiting routing decisions during crisis operations.\n\n**In this talk, you will learn about multiple aspects:**\n\n- How does your mapping in OSM directly influence humanitarian mobility analysis, and what can you do to enhance this during mapping.\n- How do we close the gap between OSM data, which is updated at a slower but steady pace during disasters, and the need for current mission-critical ground truth within the mobility analysis.\n\nThe approach we are exploring allows integrating additional critical information such as precise flood extents, infrastructure damage assessments, or security conditions provided by humanitarian responders, satellites, or other data sources. This closes the gap between steady OSM changes and information that may not be suitable for OSM or just too temporary. The unique strength of our system lies in incorporating these external data sources into routing decisions in near real time, significantly improving the relevance and timeliness of route planning. You will discover how our innovative streaming method updates routing graphs rapidly, maintaining high performance and dynamically adapting to changing conditions without the need to do time expensive routing graph rebuilds.\n\nImplemented within the open-source Openrouteservice (ORS) platform, this solution leverages a robust API that can be publicly accessed or self-hosted, ensuring broad interoperability and no technology lock-in. The development is in preview and access is still provided for humanitarian actors on demand only. This allows us to slowly roll out this functionality by still providing enough resources specifically for crisis-affected areas.\n\nThe practical humanitarian benefits are substantial. During major disasters such as Cyclone Idai in Mozambique (2019), and the 2023 Turkey\u2013Syria earthquakes, which destroyed critical infrastructure impacting access for millions, responders urgently required flexible routing reflecting rapidly changing ground realities. Our dynamic routing system enables humanitarian organizations to adapt quickly, improving response speed, safety, and efficiency, thus optimizing limited resources.\n\nLooking forward, the integration of predictive analytics based on accumulated operational data can further enhance humanitarian logistics.  Such advancements could proactively identify routes at risk, enabling a shift from reactive to anticipatory routing.\nThis talk presents the state-of-the-art integration of dynamic mission-critical data and active OSM mapping efforts into humanitarian routing, highlighting its current implementation, practical impact, and future potential for proactive, resilient humanitarian logistics.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "8RD9TG", "name": "Julian Psotta", "avatar": "https://pretalx.com/media/avatars/8RD9TG_zduuiGb.webp", "biography": "Hi, I'm Julian.

These platforms are especially valuable in regions where conventional mapping tools and data are either outdated, inaccessible, or prohibitively expensive. In underserved and resource-constrained communities, however, significant challenges persist in ensuring that the map data is current, detailed, and reflective of local realities. Limitations in infrastructure, digital skills, financial resources, and access to high-quality imagery all contribute to gaps in spatial data coverage, particularly in rapidly changing urban and peri urban environments\nTo address these challenges, this proposal introduces a cost-effective, scalable methodology that leverages street-level 360-degree imagery to enhance open mapping efforts in resource-limited contexts. By utilizing affordable consumer-grade 360\u00b0 cameras, smartphones, and community-led data collection techniques, we propose a practical approach that can be deployed in diverse environments with minimal technical barriers. The use of Mapillary  platforms as allows contributors to upload and share imagery openly, supporting global OSM editing and validation activities.\nAt the heart of this approach is the principle of community participation. Local volunteers, especially youth and members of existing mapping communities, can be trained to capture 360\u00b0 imagery by walking, biking, or driving through their neighborhoods. These community members are uniquely positioned to access areas that might be unreachable or unsafe for outsiders, while also bringing contextual knowledge that enhances the interpretation and annotation of collected imagery.

This flexibility is key to its richness and success. However, it also generates a high degree of data heterogeneity, which is often cited by its detractors or those seeking to minimize its value.\nSome services, such as dashboard.ohsome.org and github.com/hotosm/osm-analytics, have attempted to address these concerns about heterogeneity, but they seem to have been discontinued.\nThis presentation introduces a new approach that analyzes not territories as a whole or a particular theme, but rather the various components that comprise the backbone of homogeneous OpenStreetMap (OSM) data. These components include named places that are linked together and have a known extent. They are also provided with a road grid, essential points of interest, and main buildings. Finally, there are complementary points of interest.\n\nTo analyze cities and towns, this approach evaluates what defines their urban areas, such as land use zones and street networks, according to various indicators, such as age of update, geometric accuracy, and coverage. It also provides a quality or completeness index ranging from 1 to 10 with six colors ranging from red to dark green.\nBased on these urban areas, the approach also provides a completeness index for the points of interest located there. This index is categorized by type (health, education, other amenities, shops, offices) and surface of the urban area.\n\nThese indices highlight significant contrasts between regions and between small towns in the same region. The visual approach to analysis is complemented by the ability to enhance data for objects that can be edited using imagery\u00a0: a click on the map provides an opening link to JOSM. For objects that require completion in the field, we will present a workflow that uses these analysis layers and OSM applications for Android.\n\nTechnically, this approach does not use a dedicated backend served by a separate web service on the frontend. Instead, analyses are automatically produced and shared as thematic maps by country via a spatial data infrastructure (SDI) based on geOrchestra. Each produced analysis takes the form of freely accessible OGC layers (WMS/WFS) and can be used by any OGC client or downloaded in various GIS formats.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "HGCMWV", "name": "S\u00e9verin M\u00e9nard", "avatar": "https://pretalx.com/media/avatars/HGCMWV_3lvzhik.webp", "biography": "An OSM contributor (SeverinGeo) since January 2010, S\u00e9verin has been implementing programs to create and support OSM communities in the South, training in OSM and free geomatics, and mapping territories in over 20 countries since 2011, first with HOT and then through the collective that has become Les Libres G\u00e9ographes, of which he is one of the founders.

Anticipatory Action (AA) presents a paradigm shift by enabling early interventions based on forecasts and risk analysis. In Malawi, the Malawi Red Cross Society (MRCS) piloted an anticipatory approach ahead of a forecasted cyclone, demonstrating that timely action can save lives and reduce response costs by at least 15%.\n\nA critical element of the AA process was the pre identification of at risk and vulnerable populations. Using OpenStreetMap (OSM) basemaps overlaid with historical flood extents from 2015 to present, maps were generated and printed for community validation. Recognizing the limitations of satellite data, particularly in capturing flash floods, Participatory GIS (PGIS) was employed. Communities mapped flood prone zones based on their lived experience from the past decade. These hand drawn maps were digitized, returned for verification, and finalized.\n\nDue to limited resources, MRCS could only support 1,034 households. While Unified Beneficiary Registry (UBR) data was initially considered, gaps in coverage led to the adoption of the Joint Emergency Food Assistance Programme (JEFAP) approach. Communities identified the most vulnerable individuals through participatory methods. These individuals were registered using KoboToolbox, and a secondary door to door georeferenced verification exercise was conducted to refine the beneficiary list and confirm household locations in flood risk zones.\n\nWith the beneficiaries identified, MRCS worked with financial service providers to preposition cash resources. Once a formal trigger was issued by the Department of Climate Change and Meteorological Services (DCCMS), funds were disbursed in advance of the cyclone.\n\nPost distribution monitoring revealed that recipients used the cash to relocate, strengthen shelters, and protect key belongings.

In this talk, I will share my journey and lessons from working directly with local communities in Tanzania on a range of mapping projects each driven not just by data, but by people.\n\nFrom the litter assessment project in Dar es Salaam to school feeding mapping and infrastructure digitization in over 15 regions, I\u2019ve seen firsthand how mapping becomes more meaningful when communities are fully involved. My role often included training local volunteers, many of whom had never interacted with digital tools like OpenStreetMap, ODK, or QGIS to map their own surroundings. We didn\u2019t just collect data, we built relationships, encouraged curiosity, and created opportunities for people to take part in shaping their environment.\n\nThe process starts with trust, listening to the community, understanding their needs, and respecting their knowledge. This ensures that the data collected reflects lived realities not assumptions. In many cases, community members pointed out features or issues that would have otherwise gone unnoticed. Whether it was identifying informal waste dumping sites, mapping roads that never appeared on digital maps, or recording school locations accurately, the local input made the map more complete, more honest, and more useful.\n\nWe\u2019ll also discuss the importance of building capacity.

Yet, in many parts of Africa, spatial data on childcare facilities remains sparse, outdated, or completely unavailable.\nThis talk will present a community mapping initiative that aims to address this data gap by identifying and mapping daycare facilities in a Nairobi neighbourhood using OpenStreetMap tools. Through a participatory process involving local youth and community groups, the project collects geolocated data on operational daycare centers, including their names, services, capacity, contact information, and safety features.\nTo achieve this, the project utilizes QGIS for planning, digitization, and visualization of the data layers, while QField is used for efficient, mobile-based field data collection. With the JOSM plugin in QGIS, the cleaned and verified datasets are uploaded directly to the OSM platform, ensuring that the information becomes globally accessible and contributes to the growing body of open data supporting African communities.\nThe use of these open-source tools enables community members, including those with limited technical backgrounds, to engage in the full mapping workflow. The project ultimately empowers local mappers, supports better decision-making for parents, and enables local leaders and planners to identify service gaps and allocate resources more effectively.\nIn alignment with the conference theme, this initiative showcases how grassroots open mapping can connect communities to essential services, promote gender equality, and foster sustainable collaboration among residents, developers, government officials, and open data advocates.\n\n________________________________________\nKey Learning Outcomes:\n\u2022\tHow to use QGIS and QField to implement a local community mapping project\n\u2022\tPublishing collected data to OpenStreetMap using the JOSM plugin\n\u2022\tEngaging local stakeholders\u2014especially women and youth\u2014in a participatory mapping approach\n\u2022\tPractical lessons from mapping social infrastructure that serves vulnerable populations\n\n\n________________________________________\nSpeaker Bio:\nMaurine Oyugi is a Geomatics Engineer and GIS Consultant passionate about using geospatial data to address community needs.

(Darko et al., 2021). Among these vulnerable communities is Dutch Komenda in the Central Region of Ghana, a town situated along the Sosu Lagoon and the Atlantic coastline. \nIn our ongoing commitment to leveraging open data for community resilience, the YouthMappers chapter at the University of Cape Coast spearheaded a project focused on mapping coastal vulnerability in Komenda, a coastal town in Ghana increasingly threatened by climate change-induced disasters such as sea-level rise, erosion, and tidal flooding. A proposal was submitted to the Open Knowledge Foundation as part of the activities marking the 2025 Open Data Day celebration and a grant was awarded, allowing the team to collaborate with residents, community elders, and key stakeholders at Dutch Komenda to gather indigenous knowledge about previous flood events, areas most affected, critical infrastructure, and vulnerable populations. Rooted in our academic training and community-centered approach, this initiative reflects our mission to give back through actionable geospatial solutions. Using open-source tools like OpenStreetMap and SWMaps, the team engaged local stakeholders and mapped at-risk infrastructure, enabling data-driven adaptation planning. This project underscores the critical role of youth-led, open-data initiatives in addressing climate vulnerabilities and building sustainable, locally informed resilience strategies\u2014an effort we hope to share and expand through the State of the Map Tanzania platform.\nAs part of the participatory mapping methodology, a drone was used to acquire high-resolution aerial photographs of the neighbourhood, which were then used during focused group discussions and transect walks to enable community members to reference their experiences spatially.  SW Maps, an open-source mapping platform, was also utilised to collect field-based geospatial data, including floodwater depths indicated by watermarks on buildings, the locations of critical community resources, and temporary flood shelters.  According to qualitative data from the study, flooding in Dutch Komenda is mainly caused by prolonged rains, the Sosu Lagoon's insufficient drainage capacity, and choked waterways exacerbated by indiscriminate trash disposal. Floodwaters were reported to reach chest level in low-lying portions of the neighbourhood, particularly near the community centre and along key roadways, causing damage to homes, kitchens, fishing equipment, and food supplies.  Women, children, and older people were among the most vulnerable demographic groups.  The participation sessions also revealed the absence of a functional health facility, the inaccessibility of a new resettlement site, and the lack of institutional emergency preparedness procedures in the community.\nOne notable effect of participatory mapping was the creation of a composite flood risk and vulnerability map that combined qualitative insights with quantitative geospatial data.  This map identifies flood-prone locations, vital community assets, and potential safe zones, making it a valuable tool for local planning and advocacy.  \nThe project's outcomes aim to contribute to broader discussions on participatory disaster risk reduction, climate adaptation, and community resilience in Ghana's coastal context. The mapping exercise further raised awareness among the community members on the need to practice basic environmental management strategies. These include ensuring the cleanliness of the Sosu Lagoon and utilising communal labour exercises to expand the channel of the Lagoon. With this initiative, the chapter showcased its passion for using geospatial technologies to address environmental issues related to climate change. Apart from empowering the residents of Dutch Komenda, the project also provided evidence to make suggestions to NGOs in disaster management and government officials. The project's outcome highlights the importance of open data and the necessity of an inclusive approach in disaster management and adaptation planning, where the knowledge and skills of those who will be affected by the plans are taken into account. \nIn summary, the participatory mapping on flood hazard and vulnerability in Dutch Komenda serves as a perfect example of how indigenous knowledge, coupled with open geospatial tools, can help drive positive change in communities under constant pressure from climate change impacts. This approach is recommended to other YouthMappers chapters and geospatial associations in Ghana and beyond to collaboratively assist local communities in finding scalable means to analyse and address their environmental challenges. By fostering collaboration, community members appreciate their efforts and take ownership of the project's outcome, laying a solid foundation for future interventions aimed at protecting sustainable livelihoods and ultimately building resilience. \nKeywords: Participatory Mapping, Sosu Lagoon, Flood Vulnerability, Geospatial Tools, and Community Resilience.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "SGQMQF", "name": "Andy Asamoah Bimpong", "avatar": null, "biography": null, "public_name": "Andy Asamoah Bimpong", "guid": "bd96022d-48c5-58df-87e6-32c2b66898c5", "url": "https://pretalx.com/state-of-the-map-africa-2025/speaker/SGQMQF/"}], "links": [], "feedback_url": "https://pretalx.com/state-of-the-map-africa-2025/talk/HV7NPZ/feedback/", "origin_url": "https://pretalx.com/state-of-the-map-africa-2025/talk/HV7NPZ/", "attachments": []}, {"guid": "f55e016e-ab02-5e19-9664-e692fd81559e", "code": "LYHZDE", "id": 75016, "logo": null, "date": "2026-06-26T12:40:00+03:00", "start": "12:40", "duration": "00:20", "room": "Audition Room - 2nd Floor -80", "slug": "state-of-the-map-africa-2025-75016-the-role-of-osm-data-in-enhancing-cycling-an-environmentally-friendly-means-of-transport", "url": "https://pretalx.com/state-of-the-map-africa-2025/talk/LYHZDE/", "title": "The Role of OSM Data in Enhancing Cycling, an Environmentally Friendly Means of Transport", "subtitle": "", "track": "Humanitarian", "type": "Talk", "language": "en", "abstract": "Cycling is increasingly recognized as one of the most environmentally friendly, affordable, and inclusive modes of transport. In the African context, it holds great potential to address challenges such as urban congestion, air pollution, rising fuel costs, and limited access to public transportation, especially for low-income populations. However, the adoption of cycling in many African cities and towns remains low due to inadequate infrastructure, poor safety conditions, and a general lack of data to inform planning and policy.\nThis talk explores how OpenStreetMap (OSM) data can be leveraged to support and promote cycling as a sustainable mode of transport across Africa. As a free, editable, and community-driven mapping platform, OSM provides a powerful tool for collecting and visualizing data on road networks, bike lanes, terrain, traffic conditions, and services such as bike shops or repair points. In many African contexts where government data is outdated, incomplete, or inaccessible, OSM offers an alternative source of geospatial information that can be used by a wide range of stakeholders, from urban planners to cycling advocacy groups.\nDrawing from real-world experiences in African cities such as Accra, Dar es Salaam, and Nairobi. This presentation highlights how local mapping communities are using OSM to identify gaps in cycling infrastructure, map existing routes and conditions, and create open datasets for routing applications and transport planning. The session will also examine the role of youth-led and community-based mapping initiatives, which are not only contributing valuable data but also raising awareness about non-motorized transport and its environmental benefits.\nThe presentation will demonstrate how tools built on OSM, such as CyclOSM, Mapillary, etc., can be applied in African settings to support safe cycling navigation, infrastructure development, and public participation in transport decision-making. It will also address key challenges such as limited internet access, low mapping literacy, and data quality concerns, and propose strategies for building local capacity and fostering collaboration among cyclists, technologists, urban planners, and policymakers.\nUltimately, the talk will argue that enhancing cycling through open data is not just a transportation issue, but also a pathway to climate resilience, health equity, and inclusive urban development. By harnessing the potential of OSM, African communities can drive locally relevant solutions that promote sustainability, reduce emissions, and make cities more livable for all.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "JCYKQZ", "name": "Bapaala Alhassan Zuliatu", "avatar": "https://pretalx.com/media/avatars/JCYKQZ_9xFGTXR.webp", "biography": "Bapaala Alhassan Zuliatu is a student at Kwame Nkrumah University of Science and Technology (KNUST), Ghana, pursuing a BA in Geography and Rural Development.

It brings together territories, stakeholders, projects, useful documentation resources, and, crucially, a powerful mapping space enriched with highly relevant spatialized indicators.\n\n*Design and Planning*\nThe initial phase involved laying a solid foundation for the project. The first step was to clarify the objectives: what problem will the GeoPlatform solve, and who are its target users? From there, we established a detailed list of required functionalities, ranging from interactive map visualization and place search to more advanced tools like spatial queries and data export (GeoJSON, etc.).\n\nIn parallel, essential work was carried out on user experience (UX) and user interface (UI). The goal is to create intuitive user journeys and design visual mock-ups for an interface that is powerful, simple, and pleasant to use, centered on fluid interaction with the map.\n\n*Technical Architecture*\nFor flexibility and scalability, the GeoPlatform is built on a microservices architecture. This approach allows for decoupling the different components of the application (e.g., data management, map display, authentication), facilitating updates and maintenance.\n\n*Development and Testing*\nDevelopment proceeded in agile sprints, allowing for rapid deliveries and continuous adjustments. The backend team sets up the database, develops OSM data import scripts, and builds the APIs. Simultaneously, the frontend team develops the user interface, integrating the map and connecting it to the APIs to display the data. Throughout the process, unit and integration tests are automated to ensure code quality and stability.\n\n*Deployment and Maintenance*\nOnce developed, the application has been deployed on a cloud infrastructure to ensure high availability and optimal scalability. Regular updates will ensure continuous improvement of the GeoPlatform's functionalities and security.\n\n*Each OpenStreetMap community will have full autonomy to manage and customize its own platform.*", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "78M7RL", "name": "WILLY FRANCK SOB", "avatar": null, "biography": "En tant que Pr\u00e9sident de l'association   GeOsm, je pilote le d\u00e9veloppement et la mise en \u0153uvre de solutions g\u00e9ospatiales innovantes.

With 17 YouthMappers chapters, Nigeria fosters geospatial expertise among students, yet volunteer mobilization faces significant hurdles. Limited funding creates a great barrier to effective volunteering, restricting access to essential tools like laptops and smartphones while high mobile internet  data subscription cost and unreliable internet connectivity impede data collection and uploads, particularly as students\u2019 upkeep does not cover cost of internet for volunteering projects. Low awareness of OSM\u2019s societal impact, coupled with economic pressures and a weak volunteer culture, discourages consistent participation. Gender imbalances and insufficient leadership further challenge community engagement, limiting the initiative\u2019s scalability. During Industrial Training with Unique Mappers Network in Port Harcourt, I experienced these obstacles firsthand. The prohibitive cost of mobile data curtailed contributions to OSM due to lack of funding and donation to provide free internet access at the mapathon center,where student volunteers mobilized to be engaged with various humanitarian response mapping projects.   Mobilizing volunteers was daunting, as many prioritized income-generating opportunities over unpaid mapping efforts. Despite these setbacks, open mapping remains vital for youth geospatial skill empowerment as well as addressing geospatial data gaps in  local challenges, such as flood mapping and urban development. To surmount these barriers, increased funding of Local community NGOs like Unique Mappers Network, targeted OSM data awareness campaigns and mapping projects ,as well as collaborations with academic, government agencies and international agencies  i are essential to bolster volunteer engagement and elevate the quality of Nigeria\u2019s geospatial data, unlocking its potential for transformative impact using the OpenStreetMap. \n\nKeywords: OpenStreetMap, Unique Mappers Network, Geospatial data, volunteer mobilization, Nigeria", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "L9BPDF", "name": "Victor N.Sunday", "avatar": "https://pretalx.com/media/avatars/L9BPDF_HF8EG0w.webp", "biography": "Dr. Victor Ndubuisi Sunday, Ph.D.\nSenior Lecturer | Geospatial & Environmental Consultant | Founder, Unique Mappers Network | Fellow, Institute of Certified Geographers of Nigeria\n\nDr. Victor Ndubuisi Sunday is an internationally recognized leader in Geospatial Information Science, Environmental Resilience, and Citizen-Led Mapping.

Yet, a common challenge persists across NGOs and humanitarian networks: while Information Management (IM) staff may have data and reporting skills, many lack the geographic information system (GIS) knowledge needed to fully harness spatial data and to understand which data sets are of best fit. The IFRC GIS Training Platform was developed to bridge this critical gap\u2014making GIS accessible, practical, and relevant to humanitarian practitioners and beyond.\nIn this lightning talk, we will introduce the IFRC GIS Training Platform, a collaborative and open source platform that was developed in close partnership between the Heidelberg Institute for Geoinformation Technology (HeiGIT), the International Federation of Red Cross and Red Crescent Societies (IFRC), the British Red Cross, the German Red Cross and the Netherlands Red Cross\u2019 data and digital team (510). The platform provides a modular and hands-on GIS training curriculum specifically designed to match and support humanitarian use cases. It enables learners with basic IM or data skills\u2014but little or no prior GIS experience\u2014to start creating, using, and analysing spatial data effectively.\nEach training module on the platform has been created and refined in close collaboration with Red Cross and Red Crescent field and technical experts. Their feedback and real-world challenges shaped the content, ensuring it addresses genuine needs, such as mapping flood-prone areas, tracking outbreaks, or planning logistics in disaster response.\nThe platform includes interactive tutorials, real-world data exercises, a Wiki and practical examples that resonate with humanitarian professionals. From using QGIS for the first time to conducting spatial analysis with open data, like Open Street Map data, learners can walk away with skills they can immediately apply in the field.\nBeyond individual learning, the platform is designed to scale. We offer \u201cTraining of Trainers\u201d (ToT) sessions for institutions, networks, communities or teams who want to not only build internal capacity but also run their own training events. These ToT sessions, led by members of the platform consortium, equip participants with both the technical content and the pedagogical tools needed to confidently facilitate trainings themselves.\nThis training model has already been adopted by several National Red Cross and Red Crescent Societies, resulting in a growing network of GIS-savvy humanitarians who are also empowered to pass on their knowledge to others. The modular structure of the platform allows for localised adaptation and integration with ongoing capacity-building efforts, including integration with OpenStreetMap-based workflows.\nAnd for sure, the training materials are freely available online (Creative Commons Non-Commercial) and have a strong focus on open data, while not being limited to it. The materials are easy to integrate into workshops, university courses, or humanitarian training programs.\nWhat can participants expect from the talk?\nIn this talk, we will share not only the platform and its content but also stories from those who have used it: from IM officers in Red Cross and Red Crescent Societies to humanitarians discovering GIS for the first time. We'll also share partnership opportunities\u2014either by joining our upcoming ToT programs or adopting the platform in own contexts.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "7QYFKD", "name": "Melanie Eckle-Elze", "avatar": "https://pretalx.com/media/avatars/7QYFKD_QaXAjSq.webp", "biography": "Melanie Eckle-Elze is an experienced OpenStreetMap (OSM) contributor, humanitarian mapper, and Research Assistant at the Heidelberg Institute for Geoinformation Technology (HeiGIT).

Case study: Maric\u00e1 (Brazil)", "subtitle": "", "track": "Mapping: Data production", "type": "Lightning talk", "language": "en", "abstract": "The city of Maric\u00e1, in the state of Rio de Janeiro (Brazil), is historically affected by natural disasters, which mainly hit the less affluent areas of the city, where people who have fewer resources to deal with risks and damage. On the other hand, city halls in small and medium-sized cities don't always have a spatial data infrastructure or a Web mapping platform that allows for the integration of data layers related to disaster risk reduction (DRR). Given this panorama, a collaborative mapping platform is proposed, with layers related to DRR infrastructure. Seven areas vulnerable to disasters (neighbourhoods: Jardim Atl\u00e2ntico, Itaocara, Cajueiros, Mumbuca, Centro, Bananal, Jacon\u00e9), have been adopted as areas of interest (AOI) for this pilot project, which is an initiative of the Virtual Institute for Sustainable Development - IVIDES. org, in cooperation with the YouthMappers UFRJ chapter (Rio de Janeiro, Brazil), chaired by Dr. Raquel Dezid\u00e9rio Souto, chairwoman of IVIDES.org and associated researcher of the Laboratory of Cartography of the Federal University of Rio de Janeiro (GeoCart-UFRJ). Throughout 2024 and 2025, various training sessions have been carried out in order to map the seven AOI collaboratively. In order to execute the project and provide interactive data visualization, two Web maps were created, one for the acquisition an initial mapping of data in OpenStreetMap (OSM) and the other for the display of validated data in a private environment, where changes by others can be controlled. The first Web map (for raw data mapping and visualization) shows layers with data retrieved dynamically from the OpenStreetMap database using Overpass API queries, which were included in the dynamic layers of a structure developed with uMap. In this first Web map [1] it is possible to check the coverage of existing data related to the research topic in OSM and the two more used editors for OSM - iD and JOSM, can be accessed to collaborate with data missing in these AOI. The second Web map [2], developed with the Leaflet JavaScript library and the WordPress content management system (CMS), with the \u201cLeaflet map\u201d plug-in installed and active, containing the layers with OSM data that have already been validated, plus the static layers that have been added with data from the public authorities, such as data on the sirens at the hydrological or geological warning and alarm stations, which issue alarms to evacuate areas before a disastrous event occurs. A total of 16 layers are being considered initially: Areas subject to flooding; Areas subject to mass movements; Classification of the coast as its vulnerability to the coastal erosion; Schools (public and private); Geological alert and alarm stations; Hydrological alert and alarm stations; Hydrological monitoring stations; Meteorological monitoring stations; Hydrants; Hospitals (public and private); Clinic centers (public and private); Hotels; Churches; Pluviometers; Villages and towns; and Localities. For the Web map project developed with the WordPress CMS, custom icons were designed, which can be found on the GitHub [3]. The icons were designed with a black border to make them more visible on the map. The files were formatted in  Scalable Vector Graphics (.SVG) and Portable Network Format (.PNG). The second format was adopted for the Web map in WordPress, as it was better for visualization. The Web map project developed with uMap adopted simple symbols, which are present in its standard collection of symbols. Some aggregations are made for layers with a lot of data (with the clustering resource provided by uMap), in order to improve visualization and navigation on the map. The strengths of this methodology, developed for the city of Maric\u00e1, but which could be adopted by other municipalities, are that it relies on the collaborative effort of anyone minimally trained to map on the OSM and the socialization of information on disaster-prone areas with the population. However, some difficulties have been encountered, such as: i) some people have difficulty using programs and equipment needed to interact with the map; ii) weak Internet signals in locations far from large urban centers; iii) a lack of data for certain categories, such as data on the vulnerability of areas to disasters. All these difficulties have been encountered by many other researchers carrying out collaborative research and mapping. This initiative is related to the United Nations 2030 Agenda [4] and the Sustainable Development Goals (SDGs) [5], especially: SDG 3 - Ensure healthy lives and promote well-being for all at all ages; SDG 11- Make cities and human settlements inclusive, safe, resilient and sustainable; SDG 13 - Take urgent action to combat climate change and its impacts; and SDG 17 - Strengthen the means of implementation and revitalize the Global Partnership for Sustainable Development. With the progress of this research, we hope to collaborate in providing information support, not only for prevention and mitigation operations, but also for consultation with the resident population, in order to contribute to DRR in the areas covered.\n[1] http://u.osmfr.org/m/1013950/\n[2] https://ivides.org/infomarica\n[3] https://github.com/raqueldeziderio/leaflet_wp\n[4] https://sdgs.un.org/2030agenda\n[5] https://sdgs.un.org/goals", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "NYSUH7", "name": "RAQUEL DEZID\u00c9RIO SOUTO", "avatar": "https://pretalx.com/media/avatars/NYSUH7_pJoOijs.webp", "biography": "IVIDES DATA Owner (IT Consulting) - https://ivides.org/servicos.

Latest technological developments and data-driven concepts are enabling us to capture the world in unprecedented detail- with ever-growing volumes of data, promising greater resolution and coverage. But can we truly trust global models that lack local insight?\n\nResearch and real-world project examples from around the globe send a clear message: when communities on the ground are not involved, estimates, assessments, and decisions often miss the mark. This can lead to misguided \u2014 and sometimes even harmful \u2014 outcomes, with serious consequences for the very people and landscapes affected.\nSo why not turn to those who know the terrain best? Local insights and validation isn\u2019t optional \u2014 it\u2019s essential. And the good news? There are practical tools and approaches that make it easy to involve local communities in meaningful ways.\nOne of them is the Sketch Map Tool (SMT): an open-source web application developed by the Heidelberg Institute for Geoinformation Technology (HeiGIT) and the GIScience Research Group at Heidelberg University to bridge the gap between expert geospatial analysis and community-based knowledge. Driven by the aim to develop a low-tech approach to capture local insights, that does not require previous training or tech knowledge and equipment, apart from map reading and access to a phone or camera. \n\nSMT offers a low-barrier, intuitive platform for communities, NGOs, and responders to express local knowledge, risks, needs, and perceptions through freehand sketching \u2014 even in places where formal mapping data is sparse or incomplete.\n\nInspired by and building on fieldpapers, it allows users to draw spatial information directly onto a paper map using pens, to then scan or photograph the marked Sketch Maps, upload the pic/scan to the SMT website and download the pen drawn markings of the Sketch Maps in different geodata formats (raster data as GeoTIFF, vector data as a GeoJSON file). Through the use of paper maps, accessibility is enhanced and engagement is possible even in offline or analogue settings. This access is further supported through the multi-lingual setup of the SMT website, which currently contains German, English, French, Spanish and Czech, with more languages being planned.\n\nBeyond capturing tangible features like buildings, roads, waterbodies or landmarks, SMT also enables the collection of soft or intangible data \u2014 such as community concerns, perceived risks, flood-prone areas, informal settlements, and community assets or locally relevant landmarks \u2014 that are again mainly missing from conventional datasets. These maps, therefore, serve not only as a tool for data collection but also support participatory discussion processes that drive inclusion and empowerment.\n\nWhat role does Open Street Map play for the SMT?\nWhen the Sketch Maps are generated by users, they can choose from a variety of basemaps, including OpenStreetMap (OSM), satellite imagery, or other custom layers. As these base maps serve as orientation, the better and more detailed the base map, the better and more accurate marking with pens can be. \n\nSMT is integrated with the ohsome (OpenStreetMap History Analytics) dashboard, enabling users to visualise OSM data coverage and quality over time for specific regions. When a user selects an area of interest in SMT, it is automatically transferred to the ohsome dashboard, where an analysis of the completeness and recency of data in that area is performed. All analysis parameters can be adjusted to suit the specific use case.\nThis integration provides valuable insights into the suitability of OSM base map data for field data collection, helps identify existing data gaps, and supports targeted mapping efforts to improve data quality. Such analysis is crucial for ensuring reliable map-based orientation in the field, as outdated or incomplete map data can lead to misorientation, which in turn can negatively impact the accuracy of collected field data.\n\nIn previous use cases, these insights have helped ensure that the OSM database is improved directly by local communities or by organising mapping events such as mapathons to engage additional contributors.\n\nAnd how does AI support the SMT users?\nHeiGIT is making use of AI-based feature detection to support automatic recognition and digitisation of drawn features. Machine learning models are utilised to interpret both hand-drawn maps and scanned paper sketches, converting them into structured geospatial data while preserving the original community input. The models have been improved and trained with thousands of Sketch Maps to ensure that the drawings are captured as realistically as possible. \nThis fusion of low-tech data collection with high-tech processing empowers local actors without placing technical demands on them. The Sketch Map Tool is further publicly available at https://sketchmaptool.heigit.org and is designed to function well even in low-bandwidth or offline environments. \n\nWhat other developments are down the line?\nCapturing local data and ensuring that community insights are collected sustainably \u2014 without reliance on external data providers \u2014 requires bottom-up approaches.\nIn this spirit, SMT will soon integrate OpenAerialMap (OAM), enabling the use of recent satellite and, importantly, drone imagery as background layers for sketching. This integration allows users to upload their drone imagery to OAM and access it directly within SMT, supporting more detailed, timely, and locally targeted mapping efforts.\n\nAs development continues, we invite the OSM Africa and humanitarian mapping communities to test, contribute to, and collaborate on real-world applications of SMT. We especially welcome partnerships with local mapping groups, Red Cross and Red Crescent societies, and anticipatory action actors working in climate-vulnerable regions.\n\nWhat can participants expect during the workshop? \nThe Sketch Map Tool demonstrates the power of pairing inclusive, analogue-friendly community engagement with the latest advances in AI and geospatial technology. By enabling local actors to capture what they know, see, and experience \u2014 and by supporting them with powerful analytics behind the scenes \u2014 SMT fosters more relevant, representative, and timely geospatial information. It empowers communities to make their voices visible and ensures that their insights inform real-world decisions in humanitarian and development contexts.\nWe look forward to sharing this work with an intro talk followed by step-by-step walkthroughs using real-world examples of previous and current SMT users, from humanitarian, risk and vulnerability mapping to mapping of cultural landmarks, and enabling participants to directly conduct the steps themselves.\n\nWe would love to have this opportunity to enable us to learn about the ideas and challenges of the community and strengthen collaboration with the OpenStreetMap Africa network.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "7QYFKD", "name": "Melanie Eckle-Elze", "avatar": "https://pretalx.com/media/avatars/7QYFKD_QaXAjSq.webp", "biography": "Melanie Eckle-Elze is an experienced OpenStreetMap (OSM) contributor, humanitarian mapper, and Research Assistant at the Heidelberg Institute for Geoinformation Technology (HeiGIT).

It keeps people on the map, connects them to lifesaving aid, and fosters improved coordination between humanitarian responders and local players. In this panel discussion, I share first-hand experience and learning from ongoing research and mapping activities using OpenStreetMap (OSM) and GIS technologies to support internally displaced persons (IDPs) in Northeastern Nigeria, a region that is home to one of the longest-running humanitarian crises on the continent.\n\nSince 2009, the insurgency and related violence by Boko Haram have displaced over 2.5 million people in Nigeria's northeast. It is where most reside in camps or host communities that have limited access to basic healthcare, clean water, and infrastructure. There, open and collaborative mapping have played a critical role in bridging the information gap connecting humanitarian responders with populations whose needs are likely to be opaque in government data systems.\nDrawing from my experience of creating the Community Positive Health (CPH) Index and previous work of promoting spatial data initiatives with the input of OpenStreetMap contributors, GRID3, and ArcGIS platforms, I present to present three crucial issues during this panel:\n\n1. Mapping as Visibility: Making Displaced Communities Count\nIn crisis environments, invisibility too often equals exposure. The majority of IDP camps and informal settlements are not represented in national data sets, so they are underrepresented for aid access. By participatory data collection and open street maps contribution, we've been able to trace the physical size of camps, health centers, road accessibility, and water points so that frontline responders can visualize gaps and intervene.\n\nOur project combines field data gathering with Survey123 and ArcGIS Field Maps leveraging OSM basemaps to identify where services are and aren't. In Borno and Adamawa States, for instance, it helped local NGOs understand how far women in IDP camps have to travel to access maternal health care, which in turn influenced the placement of mobile clinics.\n\n2. Local Mapping Networks as Connectors\nOpen mapping is not about maps; it's about people. One of the most powerful lessons learned in the field is the role that local YouthMappers chapters, humanitarian volunteers, and displaced persons themselves have in initiating mapping projects. These mappers are intermediaries between communities and organizations translating needs into spatial data, and spatial data into action.\n\nFor example, Nigerian indigenous mapping communities assisted in mapping roads, trails, and facilities in areas where satellite data could not fully represent. Their contextual knowledge was essential in confirming OSM data and pinpointing informal health facilities not included in government records. In others, young displaced people were taught to collect spatial data, not only giving them a voice but also providing them with a skillset and returning them to society.\n\n3. Ground and Coordination Challenges\nEven within the rich tool set and talent pool of the open mapping community, coordination challenges between the global actors and grassroots base become very real. Global organizations bring resources without context, while local mappers do not necessarily lack technical tool access or organized support.\nI will present descriptions of working in this nexus overcoming data interoperability challenges, access constraints, language barriers, and ethical issues. For instance, while collecting geospatial data about vulnerable populations like women or children, community consent, privacy, and data protection norms had to be diligently observed, especially in areas of conflict.\n\nWe also had the issue of preparedness of data. When there are floods or an outbreak, time is of essence. Mapping initiated during a crisis is already too late. This is where pre-crisis mapping gains importance\u2014having ready OSM Basemaps of camps, roads, and facilities means responders aren't spending valuable hours on orienting themselves.\n\n4. Long-term Resilience Through Open Data\nPerhaps the most important lesson from the frontlines is that open mapping builds resilience after disaster. The maps don't just guide emergency response they inform policy, planning, and investment far beyond the news cycle's duration. For example, the CPH Index project is being developed as a reusable platform for governments and NGOs to find underserved populations, track change over time, and model interventions (e.g., location of new health facilities or road upgrades).\n\nTherefore, mapping is an empowering process. It creates a lingua franca across communities and institutions. It surfaces unarticulated suffering. And it generates accountability.\n\nPlanned Contributions to the Panel\nThroughout this roundtable, I'll share the following:\nField experiences of IDP camp and health facility mapping in Northeast Nigeria\nCase studies of OSM-based coordination among local mappers, humanitarians, and government partners\nPractical lessons and solutions in data collection, ethics, and multi-stakeholder engagement\nA demonstration of how mapping outputs (dashboards, maps, story maps) were leveraged to inform humanitarian response\nReflections on scaling and sustaining open mapping networks in low-resource settings\n\nClosing Reflection\nAs co-founder of Agape Global Health and Education (AGHE), a nonprofit focused on mapping health vulnerabilities and improving access for underserved children and families, I have worked directly with local stakeholders to co-create spatial tools that guide humanitarian action and strengthen community resilience. In times of humanitarian crisis, mapping has been more than a technical feat it has been an enabler, a facilitator, and a tool for justice. When people map their own lives, and when agencies value and respond to the data, we begin to build collaborative systems able to act to crisis and plan for recovery.\n\nI would like to use this panel discussion to promote a greater appreciation of the effort that goes into building those systems, and to be able to relate to others who are working to plot a more equitable future for Africa's poorest.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "AC8DSR", "name": "Olumide Stephen Ogungbemi", "avatar": "https://pretalx.com/media/avatars/AC8DSR_2QeVrJz.webp", "biography": "Olumide S.

Traditional top-down approaches often fail to address the unique, hyperlocal realities of waste generation, disposal behaviors, and service gaps. This presentation explores how OpenMap Development Tanzania (OMDTZ) with the funds from the World Bank, has implemented community-driven data collection approaches in Tanzania, Mozambique, and Kenya to fill this knowledge gap and build more responsive, inclusive waste management systems.\nThrough the integration of OpenStreetMap (OSM), mobile data tools like OpenDataKit, OsmAnd,  and participatory mapping techniques, communities have been engaged in mapping informal waste collection points, illegal dumping sites, transfer stations, and service coverage areas. By centering local knowledge, these projects have produced actionable geospatial data that informs city-level planning, supports environmental health interventions, and amplifies citizen voices in waste governance.\nParticipants will gain insights into how grassroots data collection not only improves the quality of open data but also reshapes power dynamics in urban planning placing communities at the forefront of building cleaner, more sustainable cities.\n\nDescription:\nUrban waste management systems across many African cities face severe capacity challenges. Waste collection services are often inconsistent, infrastructure is unevenly distributed, and data on where and how waste is generated and handled is largely missing or outdated. This session shares lessons from community-centered mapping initiatives implemented by OMDTZ and partners in Dar es Salaam, Nacala-Mozambique, and Mombasa-Kenya, where local residents have played a central role in generating critical waste-related datasets.\nInstead of relying solely on municipal audits or high-tech surveys, the approach engages community members, youth groups, and local organizations to map and monitor solid waste dynamics in their own neighborhoods. Equipped with mobile tools, participatory maps, and training, local data collectors document:\n\n1. Community perception and attitudes on the solid waste management\n2. Waste handling modes, disposal methods, and payment behavior\n3. Informal dumpsites and hotspots for illegal dumping\n4. Waste collection service routes and gaps\n5. Types and volumes of waste generated in residential areas\n6. Proximity of vulnerable communities to un-managed waste zones\n\n\nThese datasets are then analyzed and shared with the responsible authority, allowing governments and funders to create the city-level strategic plans for solid waste management. While researchers access real-time, location-specific information for designing targeted interventions, from optimizing collection routes to deploying behaviour change campaigns.\n\nThis talk will cover:\n1. The methodology for engaging communities and collecting waste-related geospatial data\n2. Case studies from Tanzania, Mozambique, and Kenya that demonstrate impact\n3. Tools and platforms used for data collection, visualization, and decision-making\n4. How local knowledge has influenced waste policies and infrastructure planning\n5. Challenges and solutions for sustaining community engagement and ensuring institutional uptake of data\n\nBy leveraging community knowledge and open technologies, these projects have helped cities move toward more resilient, inclusive, and evidence-based solid waste systems. The session will also highlight how this approach contributes to climate resilience, youth empowerment, and the democratization of urban data ecosystems.\nIdeal for practitioners, urban planners, open data advocates, and local government officials, this session will offer replicable strategies for harnessing community-driven data to transform waste governance and sustainability in rapidly growing urban areas.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "AB9QXF", "name": "Emanuel Kombe", "avatar": "https://pretalx.com/media/avatars/AB9QXF_FgHzeJd.webp", "biography": "Emanuel Kombe is a highly skilled professional in geography and environmental studies, specializing in OpenStreetMap (OSM) as an advanced-level contributor, head of the GIS unit, and tech.

The project is promoting STEM and climate education, problem-solving skills, knowledge sharing, and managements for a period of one year. The project's primary goal is to integrate STEM into environmental education, allowing young people to understand the importance of using STEM to create climate solutions at a young age and aligning with global climate initiatives. The project has partnered with the ministry of education, ministry of climate change and natural resources, Youth Mappers and University Environmental Clubs. The emphasis is on collaborating and co-creating knowledge with local leaders, teachers, community-based organizations, and young people in rural Lilongwe to derive environmental solutions through geospatial skills. \n\nObjectives and project justification\n\nYoung people, particularly girls and young women, are disproportionately vulnerable in Malawi, to climate change due to limited access to environmental education and awareness, particularly regarding the potential of STEM in climate action. While developed countries take bold steps to address climate change issues using STEM related approaches, Malawi lacks coordinated capacity to explore and utilize strategies that utilizes STEM, one of which being geospatial science. The project concentrates on educating 300 Young people from three marginalized communities in Lilongwe on how they can identify environmental challenges, work as teams, learn from others and fully utilize mapping skills to come up with sustainable climate solutions that work in their contexts.\n\n\nOverall objective: To train 300 young people aged between 11-20 in 3 underserved communities in Lilongwe on STEM for climate action by December 2025. \n\n\nProject Action Points:\n\n\n1. STEM and Environmental Literacy: The project is integrating STEM and environmental concepts into project activities, curriculum materials, and hands-on experiments with students. \n\n2. Implementation of 3 Youth-led climate action projects: The project is encouraging students to identify local environmental issues and design their own projects that are aided by geographic information tools to address these challenges and provide guidance and resources to support their project development, implementation, and evaluation.\n\n3. Encourage teamwork and collaboration among students: By organizing group activities, workshops, and competitions where they work together to solve environmental problems. The project emphasizes the importance of collective effort and diverse perspectives in finding innovative climate solutions.\n\n4. Establish 3 STEM for climate action hubs: Climate Education hubs have been established in all 3 communities with toolkits and documentation of the project for replication as well as knowledge sharing and management for the communities.\n\n\nImplementation Strategy\n\n1. STEM training sessions for students\n\nThe project begins with hands-on trainings in three areas of STEM and climate action, providing an overview of environmental conservation and climate change, as well as the role of young people in climate action. This is followed by lessons on technology and climate action led by Youth Mappers by teaching GIS and its integration with climate action, teaching youth how to develop solutions to climate change in Malawi.\n\n2. Action Projects\n\nFollowing the trainings together with youth mappers, environmental challenges are identified that are specific to their communities and students develop STEM-based solutions tailored to their local contexts, resulting in solutions that work in their contexts. These solutions are monitored and supported throughout the implementation of the action projects. \n\n\n3. Knowledge Sharing and Management\n\nFollowing the completion of the projects, each community conducts exchange visits to see what they have accomplished and to learn and share their experiences. The peer learning is aimed at enhancing sharing of their experiences, successful approaches, and challenges. Further areas of learning include a knowledge exchange workshop that is organized, where students discuss collective strategies for addressing Malawi's climate change issues in Lilongwe through mapping. \n\n\n4. Establishment STEM for Climate Action hubs.\n\nLessons are documented by compiling toolkits for knowledge management and establish a climate change hub in each community to facilitate easy sharing of information and learning for youth who were not part of the project.

The proliferated use of the internet and social media has escalated and ramped up the speed of misinformation-sharing, contributing to offline violence. Many communities routinely face threats from misinformation online, as well as from other sources such as television, radio, and word of mouth. Information deficits and this link between misinformation and violent conflict urgently need to be addressed, especially in conflict-prone settings. Since 2013, the Sentinel Project has been developing and expanding initiatives to manage misinformation in unstable environments, to prevent and mitigate violence. These projects have become effective mobile phone-based participatory information services for engaging communities in monitoring, verifying, and countering the spread of harmful rumours and misinformation that contribute to conflict. The inspiration for these projects was the Una Hakika pilot project, first developed in the Tana Delta, Kenya. Participants report rumours, which are investigated by the project team and a network of trained volunteers and stakeholders. Once a rumour has been verified, the facts are reported to the affected communities. The most common communication channels are SMS, voice calls, and the engagement of volunteer community ambassadors. This intake and verification process involves gathering a large amount of information from various sources, such as open mapping, open data, and GIS, and attempting to make sense of it. The next step involves mapping reports of rumours to see how they develop and spread through the area. The interface then profiles rumour reports according to the risk levels posed and provides an analysis that reinforces and determines responses and interventions. Additionally, the existing Una Hakika system can also provide real-time information on increased volatility in its operational area. More broadly, Una Hakika supports positive behavioural change among citizens by establishing, training, and equipping a broad community of practice focused on countering misinformation and other forms of harmful online content.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "U8AXWM", "name": "John Green Otunga", "avatar": "https://pretalx.com/media/avatars/U8AXWM_AOIcwyi.webp", "biography": "John is the East Africa program manager for the Sentinel Project.

As the most trafficked mammal in the world, they have faced increasing threats from habitat loss and illegal wildlife trade. In response to this crisis, the Tanzania Research Conservation Organization (TRCO) emerged as a national leader in pangolin conservation through research, education, policy advocacy, and community engagement. To complement these efforts, Geospatial Technology and Environment (GeoTE) initiated a collaborative project aimed at integrating OpenStreetMap (OSM) into the conservation landscape.\nThe initiative, titled \u201cMapping for Pangolins,\u201d brought together GIS professionals, students, conservationists, researchers, and local communities in a coordinated mapping campaign. The primary objective was to produce open, accurate, and up-to-date geospatial data to support pangolin protection, habitat monitoring, and community-based conservation planning. Using the OSM platform, participants successfully mapped key features within TRCO\u2019s focus areas such as roads, settlements, water bodies, forest boundaries, and land cover types that are often underrepresented or missing from existing datasets.\nBy leveraging OSM\u2019s collaborative and open-access nature, the project empowered local communities and students to actively contribute to environmental conservation through citizen science. Participants were trained to use OSM tools, including iD Editor, Field Papers, and GPS-based applications such as OsmAnd and Organic Maps. These efforts enabled the creation of actionable spatial data that helped TRCO identify high-risk areas for pangolin trafficking, assess human-wildlife interactions, and enhance planning for habitat protection.\nThe initiative also contributed to a broader goal of promoting geospatial innovation for environmental sustainability in Tanzania. Ensuring that the generated data remained open and accessible to stakeholders including government agencies, NGOs, researchers, and local communities, enhanced collaboration and informed decision-making at multiple levels. Follow-up sessions were conducted to validate map quality and to maintain the engagement of newly trained mappers, particularly from YouthMappers chapters across the country.\nThis project demonstrated how OpenStreetMap can serve as a vital tool in modern conservation strategies, especially in regions where data scarcity limits effective planning. The collaborative effort between TRCO, GeoTE, and the open mapping community provided a scalable and replicable model for integrating spatial data into wildlife conservation.\nIn conclusion, \u201cMapping for Pangolins\u201d showcased the power of open geospatial data and citizen participation in addressing critical conservation challenges. The initiative emphasized that protecting species like the pangolin requires not only scientific research and policy but also accurate, community-driven mapping to reflect real-world conditions on the ground. As a result, the project made a significant contribution to pangolin conservation and highlighted the transformative role of OpenStreetMap in supporting biodiversity and ecological resilience.\nThis presentation will offer valuable insights into how OpenStreetMap can be effectively applied beyond urban and infrastructure mapping, showcasing its critical role in conservation and biodiversity protection. By highlighting a real-world case from Tanzania that combines youth engagement, community participation, and geospatial innovation, the session will inspire similar collaborations globally. It will also provide a replicable model for how OSM data can support endangered species protection and habitat monitoring.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "XZPVYM", "name": "Ezekiel Edgar Kiariro", "avatar": "https://pretalx.com/media/avatars/XZPVYM_MVeXmQy.webp", "biography": "A passionate and experienced GIS and Remote Sensing expert with a strong background in open mapping, environmental analysis, and spatial data science.

We wanted to understand how food prices shift over time and space, so instead of trying to cover all 774 LGAs at once, we took a more strategic approach. We grouped local governments based on shared characteristics like urban-rural layout, population density, and building distribution, and selected 20 representative LGAs as a starting point.\n\nFor this work, we\u2019ve been using our own mobile data collection tool, WeCollect, which allows us to coordinate and manage field contributors across different parts of the country. These contributors gather price data from grocery stores, traditional markets, and even farms capturing the true range of price points across different communities and market types.\n\nThe results have been both insightful and encouraging. We\u2019ve been able to visualize food price shifts on a map, showing spatial disparities across LGAs and how urban centers often record higher prices than surrounding rural communities. These maps, created by integrating our cleaned datasets into QGIS and Leaflet.js, offer a layered view of market access, price volatility, and geographic trends. Visualizations highlight, for instance, how the cost of tomatoes in one rural LGA can be 30% less than in an urban LGA just 40km away insights that can inform public policy and targeted interventions.\n\nThis experience not only showcases how open-source mapping tools and mobile data platforms like WeCollect can work together to create usable, community-driven datasets it also underscores the importance of methodology in mapping. We look forward to sharing our technical process, challenges with contributor validation, lessons from our testing of offline tools, and how this data can integrate with OSM layers to support future socioeconomic mapping projects.

These are vibrant and dynamic neighbourhoods of varying size, recency, and characteristics. The residents of these settlements move between their neighbourhoods and other parts of the city for economic and social reasons, but also to access services not available where they live. \n\nAs informal settlements often evolve without formal planning processes, the entry and exit points that connect them to adjacent neighbourhoods are not optimised. This means that some parts of informal settlements are very well served by access routes and some are poorly served. \n\nFor persons living with disabilities in informal settlements, a lack of proximate entry/exit points or inaccessible entry/exit points can greatly exacerbate the already challenging process of accessing essential services, economic opportunity, or social networks.\n\nUsing recently acquired high-resolution drone imagery, OpenStreetMap data, and community-driven mapping approaches, the Humanitarian OpenStreetMap Team (HOT), Freetown City Council (FCC), National Commission for Persons with Disabilities \u2013 Sierra Leone (NCPD), and OpenStreetMap Sierra Leone (OSM SL) are collaborating to develop analytical methods aimed at evaluating the current state of accessibility in seven informal settlements for persons with disabilities.

This ecosystem has an important community component and a large set of software resources that serve many different purposes, such as retrieving, editing, validating or converting data, collecting data in the field, routing, geoservices... These programs are increasingly present in the daily lives of OSM users, especially in countries outside the US-Europe axis (such as Latin America and Africa), where new users are becoming interested in OSM and the applications, which\nis reflected in the significant increase in the number of contributions on the map. This research aims to survey the publication profile of the weeklyOSM [1], analyzing the content of the issues published on the last ten years (#272 to 768), since it began to be organized with the OSM Blog Collector [2], a system with free and open source code, designed, programmed and improved by TheFive [3] and which has been used to manage the content of the weekly publishings since its number 272, in September 2015. The weeklyOSM reports news from the reporting week, is produced by mappers and OSM enthusiasts and is independent from organizations and companies [4]. It covers currently 15 languages and has been informing the OSM user community without fail since its release as the German weekly OSM-Wochennotiz [5], whose initial issue was published on July 23, 2010. Its workflow naturally favors sampling OSM-related topics from a wide variety of sources, such as social networks, blogs, OpenStreetMap Foundation channels or institutional news sites. Thus, by analyzing their content, it is hoped that the results will serve as a proxy for understanding the interest in certain categories and the usage of certain software by OSM users. The methodological flow started with the initial export of the articles stored in the OSM Blog Collector (OSMBC), in a file in .CSV format. The records were then imported into a PostgreSQL database and analyzed using SQL. Of the initial 32,261 records (articles) and 35 categories, the records prior to number 272 were excluded and the categories were standardized to conform to the actual weeklyOSM's categories (About us, Breaking news, Community, Did you know that..., Education, Events, Humanitarian OSM, Imports, Licenses, Local chapter news, Mapping, Mapping campaigns, Maps, Open Data, OpenStreetMap Foundation, OSM in action, OSM in the media, OSM research, Other Geo Things, Picture, Programming, Releases, Software, Upcoming Events). Thus, after the initial processing, 18,672 records (articles) were obtained, classified into the current 24 categories and considered as the initial set for the analysis. In a second stage, queries were made regarding the occurrence of 102 software in the articles (e.g. \u201cPanoramax\u201d), saving the results files in .csv format and making them available on GitHub [6], with its\nsubsequent classification into 14 software groups (3D model, aerial imagery, API, converter, data extraction, data quality, desktop editor, library, mobile editor, notes editor, OSM based service, routing, street level imagery, tagging) and re-importing them into the database in a new table, forming a second set of records. Making the data and results available on GitHub guarantees the transparency and reproducibility of the analysis. The search for software and the design of the categories were inspired by the sources [7-11]. From the starting set for the analysis, the initial and final numbers of the category (e.g. \u201cMapping\u201d) were collected, and the total number of articles in the category was calculated, resulting in a ranking showing the most popular categories for publishing articles. From the second set (only the records of the 102 selected software), the software' indices were calculated, which correspond to the software's participation in the group to which it belongs. The results found in the first stage of the analysis show that the ten most popular weeklyOSM categories to associate with articles were: \u201cMapping\u201d (2,778 articles), \u201cOther geo things\u201d (2,331), \"Community\" (2,212), \u201cDid you know that...\u201d (1,177), \u201cEvents\u201d (1,153), \u201cMaps\u201d (1,064), \u201cSoftware\u201d (1,060), \"Programming\" (963), \u201cHumanitarian OSM\u201d (821) and \u201cOpenStreetMap Foundation\u201d (782); and the full ranking can be accessed on the GitHub [12]. In the second stage of the analysis, with the set of data which contains only the records of articles that included the 102 selected software, two main statistics were obtained: i) the number of articles for the 14 groups of software and ii) the participation index of a given software in the group to which it belongs. For the first processing (i), the five groups with the highest number of articles were: \u201cDesktop editor\u201d (1,193), \u201cOSM based service\u201d (968), \"Routing\" (524), \u201cMobile editor\u201d (522) and \u201cStreet Level Imagery\u201d (424); and the full results are found on the GitHub [13]. For the second processing (ii), there was a greater variety of software in the \u201cOSM based service\u201d, \u201cDesktop editor\u201d and \u201cMobile editor\u201d groups; the complete set of graphs are found on the GitHub [14]. As a result of the research, we could infer that weeklyOSM, over the last ten years, has expressed the variety of themes and programs related to OSM, with a large representation of content pertinent to \u201cmapping\u201d and \u201ccommunity\u201d, which are at the heart of the OSM ecosystem. Thus, could be inferred that the analysis had a representative result from the point of view\nof reality; and c) in addition to this \u201cpanoramic\u201d view of the content in general, it was possible to observe the participation of the software in their respective group, inferring their relevance in the context of the collaborative mapping with OSM. Limitations of the research include the difficulty in performing queries on very heterogeneous strings, requiring greater attention from the researcher and the static nature of the analysis, making it more time-consuming to carry out the workflow. With the publication of this research, we hope to highlight the wide variety of information resources available to OSM contributors and, in particular, to highlight the role of weeklyOSM as a representative vehicle for information on the OSM ecosystem, freely accessible to the community and which has fulfilled its objective without fail since its first edition on 2010.\n\n[1] weeklyOSM Editorial Team. weeklyOSM. https://weeklyosm.eu\n[2] weeklyOSM Editorial Team.

The Paris Agreement on Climate Change has prompted some countries to enforce institutional reporting of carbon emissions and mitigation actions. Emitters can mitigate their emissions by adopting low-emission technologies or investing in offsetting programs. In 2022, the Malawi Liverpool Wellcome Programme invested in a carbon offsetting program involving tree planting on Mulanje Mountain. This study, we expanded our remote sensing project on mapping plastic waste accumulating in the environment to aid monitoring of these trees and estimating their carbon storage potential. We conducted field surveys using transects to assess tree survival, collecting data with KoboCollect. Field-level pictures of the transects were captured to aid in the identification of vegetation species, which is being conducted by a professional ecologist. Drone images of the planted trees were collected using a DJI Mavic 3M, capturing both optical and multispectral reflectance (infrared and near-infrared). The images were processed with OpenDroneMap to produce a seamless orthomosaic map and a 3-D model of the planting plot. We are training an automatic classifier to identify the planted trees and invasive species from the drone imagery. Field-based monitoring revealed 73 planting stations, with 39 stations having surviving trees, representing a 54% survival rate. The monitored vegetation included grown trees, shrubs, pine trees, weeds, grass, and other invasive species. Drone images from two sites have been processed, and efforts are underway to annotate the data to identify tree planting stations and surviving cedar trees to quantify tree survival. The ongoing study has the potential to enhance the transparency of offsetting programs, particularly tree-planting campaigns. Once the classification model is finalized, it will improve field-based tree monitoring, providing rapid insights into tree survival and facilitating appropriate compensation or replacement actions.

Landsat-7 ETM+ (2014) and Landsat-8/9 OLI/TIRS (2023) imagery were analyzed to classify LULC and extract water indices. Water quality was indirectly assessed using the Normalized Difference Water Index (NDWI) and Modified Normalized Difference Water Index (MNDWI), Over the study period, water bodies declined from 89 to 9 hectares, and vegetation cover reduced from 1,315 to 359 hectares. In contrast, built-up areas expanded from 1,450 to 2,486 hectares, reflecting intensified urbanization.

NDWI values, already negative in 2014 (ranging from -0.3430 to -0.2812), declined further in 2023 (ranging from -0.0101 to -0.0612). These shifts reflect a diminishing presence of strong water signals across both years. Change detection further reveals that NDWI recorded a total water loss of 368.38 ha, while MNDWI showed a smaller loss of 77.21 ha. This contrast highlights that NDWI captured broader, more general water loss including turbid and mixed-pixel areas, while MNDWI, which is more sensitive in urban settings, detected more conservative changes, primarily in clearer water bodies.

The capital, Khartoum, has been particularly devastated with unparalleled destruction and disruption of essential services. In this context, timely, precise, and open geospatial data have emerged as a critical resource for humanitarian response and urban recovery planning. OpenStreetMap (OSM), a worldwide collaborative mapping platform, seems to be a good base for such activities. This paper examines the applicability of using Open Street Map (OSM) data for mapping urban infrastructure and population distribution in Sudan conflict zones.\nThis study offers a systematic methodology to evaluate, process, and leverage OSM data for development planning and decision-making in the context of conflict and post-conflict.\n\nThis study has two main aims, to assess the spatial completeness and reliability of OpenStreetMap (OSM) building versus health infrastructure coverage across Khartoum and neighborhood and to illustrate how OSM building and health infrastructure data can be integrated with population, remote sensing, and conflict event data to inform targeted humanitarian response and reconstruction efforts. A second objective is to assess how community-led mapping activities and workshops contribute to enhancing the quality and capacity of local mapping activities and operations.\nWe adopted a methodology that combines spatial analysis, empirical evaluation, and participatory mapping practices. First, we extracted OpenStreetMap (OSM) building footprints and health-related features (e.g., hospitals, clinics, and pharmacies) using the Overpass API and the Humanitarian OpenStreetMap Team (HOT) export tool. We then compared these datasets with historical pre-conflict basemaps and third-party authoritative sources, when available. We evaluated completeness, positional accuracy, and attribute quality through visual inspection and quantitative spatial metrics.\nA central component of our approach was organizing local mapping workshops. In partnership with universities, humanitarian NGOs like Khartoum Reconstruction Initiative (KRI), and volunteer mappers in Sudan and the diaspora, we held these workshops, which focused on mapping missing infrastructure in OpenStreetMap (OSM), validating existing features, and training participants in using geospatial tools for crisis mapping. There was a strong response from local mappers, particularly youth and university students. We documented how this participatory model contributed to data enrichment and capacity building in digital cartography and open data literacy.\n\nOur analysis revealed key results, including over 150,000 building footprints and more than 500 health facilities tagged in OSM within Khartoum state. While urban centers showed relatively high completeness, peri-urban and rural areas exhibited considerable data gaps, particularly in the classification of public infrastructure and emergency services. Spatial overlays with conflict zones showed that many high-density residential areas had significant infrastructure damage, which was corroborated by satellite imagery. Our analysis also showed that many previously mapped health facilities were now inaccessible or damaged, highlighting the urgent need for updated data collection.\nThrough a comparative analysis of raster land cover data from 2019 and 2022 (TIF), we calculated pixel-based change detection using ArcGIS Pro\u2019s Raster Calculator and statistical tools. This enabled us to identify areas with gains (where land cover increased or improved), areas with losses (where land cover or buildings were destroyed), and areas with no change. We visualized these classes through bar charts using Matplotlib and exported them as CSV summaries. The gain-loss-no-change classification communicated spatial trends to decision-makers and humanitarian agencies.\nThis study makes several scientific and practical contributions. From a scientific standpoint, it demonstrates the feasibility of using volunteered geographic information (VGI), such as OpenStreetMap (OSM), in complex, resource-limited, and crisis-affected environments. The study also proposes a reproducible, scalable methodology for evaluating OSM completeness, performing raster-based land change analysis, and integrating multiple spatial datasets to inform humanitarian responses. Our approach emphasizes reproducibility; all scripts, data sources, and analysis tools are openly available under open licenses, and our methodology is documented step by step for replication.\n\nFrom a practical standpoint, this work supports humanitarian organizations by providing them with reliable spatial products and analytics derived from OSM data. It also strengthens local capacity by training communities in mapping tools and geospatial thinking. Training materials, workshop models, and mapping protocols developed through this initiative have been adopted by organizations such as Map4Sudan, HOT, and UN agencies working in the region.\n\nIn terms of impact, the project has demonstrated that open mapping can be an essential component of crisis response and recovery. By enabling community members to participate in data creation and verification, the project has increased trust in open data and promoted civic engagement. The project has also laid the groundwork for a broader digital resilience strategy in Sudan and other conflict-affected African countries, where official data may be outdated, unavailable, or politically sensitive.\nIntegrating scientific spatial analysis with community-based mapping demonstrates the power of OpenStreetMap (OSM) as not just a map, but also as a living, adaptive infrastructure for crisis resilience. Thus, OpenStreetMap should be recognized as a strategic digital asset and integrated into national spatial data infrastructures (NSDIs), urban planning frameworks, and emergency response systems.\n\nFuture work will include more in-depth assessments of OSM temporal dynamics, using artificial intelligence for damage detection based on OSM basemaps and satellite imagery, and developing real-time dashboards for humanitarian coordination. We also recommend that academic and humanitarian institutions collaborate to incorporate participatory mapping into school and university curricula to foster sustainable mapping ecosystems across the continent.\n\nKeywords: OpenStreetMap, Sudan conflict, Khartoum, buildings, health infrastructure, population mapping, humanitarian GIS, urban resilience, VGI, collaborative mapping, geospatial analysis, crisis response, post-conflict recovery.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "FRJZ9J", "name": "Nisreen Mahmoud", "avatar": "https://pretalx.com/media/avatars/FRJZ9J_wfu7XGE.webp", "biography": "Nisreen Mahmoud is a GIS and Remote Sensing Expert with a specialization in environmental analysis, post-conflict assessment, and urban resilience.

These challenges are exacerbated by infrastructural gaps, limited access to spatial data, and a lack of locally informed decision-making tools. While traditional mapping often fails to capture the dynamic nature of community vulnerabilities, open mapping\u2014especially via OpenStreetMap (OSM)\u2014offers a participatory and scalable alternative for resilience planning. Despite its potential, there remains a gap in systematically integrating artificial intelligence (AI), machine learning (ML), and community-centric data into open mapping workflows to generate real-time, actionable insights.\n\nMain Aim and Purpose of the Study\nThis study presents a methodological framework that integrates AI-assisted image classification, open geospatial tools, and community-driven data collection to improve spatial awareness, resource allocation, and emergency preparedness in vulnerable regions. The research specifically evaluates how open mapping, powered by AI and community collaboration, enhances flood response, healthcare delivery, and environmental monitoring in under-resourced areas of Nigeria, South Africa, and Kenya.\n\nMethodology\nOur approach combines multiple methodologies:\n\nData Acquisition: Using drone imagery and Sentinel-2 satellite data over targeted regions, including flood-prone and informal urban settlements.\n\nAI/ML Integration: Applying convolutional neural networks (CNNs) and supervised classification models (e.g., Random Forest, U-Net) to extract features like road networks, buildings, vegetation cover, and flood extent.\n\nCommunity Validation: Engaging local mappers and community leaders in YouthMappers chapters to validate automated outputs via MapSwipe and Field Papers.\n\nToolchain: Leveraging QGIS, JOSM, Google Earth Engine, and the OSM iD editor alongside custom Python scripts for model deployment.\n\nQuality Assessment: Performing intrinsic and extrinsic quality assessments using metrics such as positional accuracy, semantic accuracy, and completeness based on ground truth surveys and authoritative data sources.\n\nKey Findings\nThe integrated workflow improved map coverage in three pilot regions by over 70%, while reducing the time required for feature mapping by 60% compared to manual-only methods. In areas with recurrent flooding, risk zones were identified with 92% classification accuracy, enabling proactive community evacuation planning. Engagement with community mappers increased map validation rates and fostered digital inclusion, especially among women and youth. The framework also demonstrated the capacity of AI-augmented mapping to support real-time decision-making during emergencies, with significant potential for scalability across other African countries.\n\nScientific Contribution and Practical Benefits\nThis research contributes to the growing body of knowledge on AI-enhanced participatory mapping by:\n\nPresenting a reproducible, open-source mapping workflow that integrates machine learning with local knowledge.\n\nDemonstrating how AI can complement rather than replace human mappers in producing high-fidelity, inclusive spatial data.\n\nProviding insights into the sociotechnical challenges of implementing such systems in low-resource settings (e.g., power outages, digital literacy gaps).\n\nHighlighting how open mapping can bridge the gap between geospatial technology and humanitarian resilience planning.\n\nAll scripts, data, and trained models will be published in a GitHub repository under an open-source license to ensure reproducibility. Data outputs will be uploaded to OpenAerialMap and OSM for community use, while metadata and evaluation protocols will be documented in the Zenodo repository.\n\nImplications for the OSM Community\nThe results show that AI-assisted mapping, when combined with inclusive community practices, offers an effective pathway for increasing the utility, adoption, and sustainability of OpenStreetMap in Africa. The approach provides a scalable solution to both routine and disaster mapping in settings with limited resources. By fostering knowledge exchange between researchers, local mappers, and humanitarian actors, this study opens new directions for collaborative geospatial innovation and ethical data governance in Africa\u2019s mapping ecosystem.\n\nKeywords: OpenStreetMap, AI-assisted mapping, disaster resilience, participatory mapping, satellite imagery, YouthMappers, QGIS, open geospatial science, humanitarian response, African data innovation", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "EM8PYM", "name": "Nwosu Obinnaya Chikezie Victor", "avatar": "https://pretalx.com/media/avatars/EM8PYM_v6e9lNu.webp", "biography": "Nwosu Obinna Chikezie Victor is a multidisciplinary researcher and geospatial technology enthusiast with expertise in geophysics, environmental science, artificial intelligence, and open mapping.

Understanding location and travel accessibility affects how a person can travel to access primary healthcare \u2013 as areas that are further away from a facility strongly benefits from a telehealth initiative.\nGeographically identifying under-reached populations and applicable population segments to target interventions, understanding where current health system delivery gaps in facility and service availability and poor geographic/physical access to health facilities and low performance. The Lagos Innovation portfolio, a geospatial analysis performed by members of the Geospatial Insights Support Team (GIST) from DevGlobal and Dev-Afrique Development Advisors, aimed to analyze and identify underserved communities who could potentially receive telehealth interventions for an interventional research study conducted by Solina Centre for International Development and Research (SCIDaR) and VillageReach.\n\nMethods \nGeospatial datasets were procured from GRID3, OpenStreetMap, and OpenCellID, while tabular datasets were acquired from the Nigeria Federal Ministry of Health, the Lagos Bureau of Statistics, and the Lagos Primary Healthcare Board. \nGRID3 population density data from 2021 (quantified as high, medium, and low), which demonstrates the distribution and intensity of human activity across all 20 LGAs, was overlayed with the coordinates of existing health facilities obtained from the Lagos Primary Healthcare Board. The existing health facilities were mapped with their primary, secondary, and tertiary-level healthcare facility levels. Additional information, such as their operational status, as defined by the Nigeria Federal Ministry of Health\u2019s Master Facility Lists and Health Facility Registry, public/private status, and clinical staffing levels, were also incorporated for each facility.\nA 3km buffer was created around each active healthcare facility to show the estimated coverage of healthcare services, a more conservative estimate compared to the World Health Organization\u2019s 5 kilometers optimal distance for healthcare accessibility. As a result, areas outside the 3km buffer were staked as potential intervention locations for the telemedicine study. These areas of potential intervention were further overlayed with Google Earth imagery and OpenStreetMap road network data to precisely map areas of considerable development and human activity. \nFor each LGA in Lagos state, a set of socioeconomic indicators \u2013 such as gender (male/female), income level (low or high), education level (elementary or advanced levels), housing type (based on building size, rental/ownership costs and luxurious building features), and employment type (high/low) - were obtained from the Lagos Bureau of Statistics, categorized and appended to each LGA.  Potential service points were then overlaid on top of the LGAs with appended socioeconomic indicators. \nAdditional analyses were performed to analyze the effects of travel time and cell signal catchment areas. Travel time catchments were determined in Python using OpenStreetMap road networks (including routing information), and the osmnx, networkx (to Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.), and sklearn Python modules to (1) download, model, analyze and visualize street networks and incorporate speed, travel time, and routing, (2) create, manipulate, and model the complex road network, and (3) analyze the projected graph network. The travel time catchment area, determined as the number of intersections that could be traversed within a 20-minute time, was determined for both driving (using a 30km/hr. speed) or walking (using a 5km/hr. speed) scenarios. These catchment areas were overlaid on the circular buffer areas. Areas selected were typically those with high measures of poverty (e.g., low income, poor housing type and/or employment type) that were outside of the healthcare-accessible buffer areas. \nAnother auxiliary analysis, to map cell signal catchment areas, was performed to help guide potential telemedicine initiatives. Tower location coordinates were obtained from OpenCellID, which contained information about the tower location, the type of transmission (2G, 3G, 4G, and 5G), and other indicators. Each tower location had a buffer mapped around it, equivalent to the radius (\u201crange\u201d) of transmission. The individual tower buffers were merged together for each type of transmission, using dissolve in QGIS, to create a zone for each transmission type. \n\nResults\nA total of 26 potential service points were identified as underserved areas across different local government areas (LGAs) and local council development areas (LCDAs) in Lagos. These locations were found in Ikorodu (6), Ibeju Lekki (5), Badagry (2), Ojo (2), Alimosho (2), straddling Ojo and Alimosho (1), Ifako Ijaye (1), Amuwo Odofin (2), straddling Oshodo-Isolo/Ikeja (1), Lagos Island (1), Eti Osa (1), and Epe (1) LGAs.\nWhen analyzing the distribution of primary healthcare facilities, including community health centers, rural health clinics, paediatrics practices, family medicine practices, etc., about 70 percent of the total healthcare facilities in Lagos state were made of such facilities, with more primary healthcare facilities occurring in higher-population density areas LGAs (e.g., Alimosho, Badagry, Eti-Osa, Kosofe, Ikorodu, and Ojo). Additionally, it was found that private HCFs were more prevalent than public HCFs in the higher-density locations. Our results also suggested a low population of clinical staff occurred across the state. \nWhen using calculated travel time from each underserved point, it was found that the travel time-specific catchment areas often went further outside of the circular buffer zone used to signal healthcare accessibility. When incorporating the travel time buffers into the analysis, the number of communities captured as part of each catchment area were often much higher than those captured solely by the circular healthcare accessibility buffer.\nThe majority of cell signal network types encountered in underserved communities are 2G, according to an analysis of cell signal range and LGA data, with 3G and 4G services available in more population-dense areas of the state.\n\nDiscussion\nBy utilizing a hybrid approach of mapping and spatial overlay of local health facilities, telecommunications access, road networks, travel time catchments and various socioeconomic indicators, our team was able to identify a shortlist of 26 underserved settlements across 11 LGAs in Lagos state that could be potentially be best serviced by a telehealth intervention.\nAfter these initial results were disseminated by the GIST in May 2023, these results were passed to SCIDaR and VillageReach for a telemedicine research intervention study, \u201cImplementation Research to Test Equitable Digital-First Care in Lagos\u201d.

The ever rapid rise and growth of the usage of OSM data in developing countries with diverse cultural and ethnic compositions has called for the need to give attention to the concerns that have been frequently raised about accuracy and reliability of its data culturally. Since OSM data is collected by volunteers with varying degrees of expertise and access to accurate data sources, data quality can vary widely across regions cultural peculiarities of settlements\u2019 place names (toponyms) is inseparable. The purpose of this study is to cartographically analyse the cultural significance of toponyms, and positional accuracy of OSM data. Toponyms are peculiar to culture of people in a particular geographic environment which can be found in various forms such as Oronyms-name of mountain/hills; hydronyms-name of rivers, lakes or ocean; Urbanonyms-names of cities, towns, villages; and Geonyms- names of geographic features such as mountains, valley, or deserts. The study also paid attention to spatial pattern of settlements, and density of road network across the thirty-three Local Government Areas of Oyo State. \nThe study employed the use of mixed method approach to collect qualitative and quantitative data. To this effect, both primary and secondary were collected. Secondary data of OSM for Nigeria was downloaded from OpenStreetMap website, and clipped to the administrative boundary of the study area using Political boundary of Oyo State Local Government Areas (LGA) obtained from State Ministry of Lands and Urban development. Ground truthing of missing and misplaced settlements was obtained with Global Positioning System Garmin 76X device with random sampling of settlements through fieldwork constituted the primary data, and supported with Google Earth Pro map. Research work on Yoruba cultural name of settlements provided the compendium of correct spelling of settlements in Oyo State, as well as their changes overtime (toponymy). The various forms of toponyms as outlined above were verified, and those found to be inconsistent with OSM data were quantified and analysed for each LGAs in the study area. Cartographic visualization and mapping. Average Nearest Neighbour statistics was used to analyze the spatial pattern of OSM settlements (places) for each LGA. Similarly, Network analyst was used to analyze the density of road with the measured area dimension of each LGA using ArcMap 10.8 software. Pearson correlation technique was used in to examine the relationship between incorrect place name (toponyms), and positional inaccuracy of settlements (duplication, missing, and inaccurate locations). Observed duplicate Settlements vary across the LGAs. \n\nThis study observed that duplicated settlement locations exist which varies significantly across the LGAs. High percentage of settlement duplicated in the same location were found in Ibarapa North, Ona Ara, Ibarapa East, Ibarapa Central,  and Saki East LGAs accounting for 33.65%, 28.38%, 27.95%, 25% and 25% respectively. This indicates that a significant portion of settlements in these areas are listed multiple times with different names or data points. In contrast, Ibadan South east, Ibadan North-East, and Ibadan North-West have 0% duplicate settlements, meaning that no duplicate settlement locations were recorded for these areas.\n\nThe findings of this study revealed that there is a statistically significant positive relationship (r = 0.704, p = 0.000) between the number of inaccurate settlement locations and incorrect spelling (toponym). This finding indicates that areas with poor positional accuracy are more likely to exhibit spelling errors, and vice versa. Average nearest neighbor analysis confirms that settlements in Oyo State are significantly clustered, as evidenced by the Nearest Neighbour Index (NNI) of 0.596139, highly negative Z-score (-41.556355), with extremely low p-value. Positional accuracy assessments also revealed that 69.6% of OSM settlement data aligns with ground-truth observations. However, overall positional inaccuracy rate of 30.37% was recorded across the thirty-three (33) LGAs of Oyo State. This points to the fact that, there is a notable variation in OSM data reliability. LGA such as Orelope recorded 100% positional inaccuracy, indicating severe mapping deficiencies. This has negative effects on geospatial mapping and analysis in such area. Similarly, LGAs such as Ibarapa North, Akinyele, and Orire exhibit high positional inaccuracies, while others show lower error rates indicating a high level of accuracy of OSM data. \n\nTo enhance OSM data quality, this study recommends increased local participation in data contributions, integration of authoritative sources, and the use of automated validation tools. These measures will improve data accuracy and usability, benefiting urban planning, disaster management, and infrastructure development for geospatial analysis as well as community development. The study contributes to the broader Volunteered Geographic Information (VGI) quality assessment field by providing a replicable framework for evaluating geospatial data accuracy and reliability in similar contexts.\n\nKeywords: Toponym, GIS, OSM, Positional accuracy, Cartographic visualization, VGI", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "HL3DQK", "name": "Joseph", "avatar": null, "biography": "Joseph Muyiwa Olumoyegun, is a trained Cartographer with National Diploma in Cartography, B.Sc.Geography,  M.Sc.

While some public spaces lack the sense of safety or adequate amenities for women\u2014particularly mothers\u2014other spaces unexpectedly offer women-friendly environments. What are the socio-spatial characteristics that ensure women\u2019s spatial conviviality? And how can public spaces be assessed in relation to women\u2019s lived experience?\nAs part of a Ph.D. thesis (2024), the social project called (Madinatouha) was developed to create an assessment tool that combines an index with collaborative mapping. Sixteen indicators were identified after an extensive literature review, and grouped into four main axes (Safety, Dignity, Functionality, and Comfort), each considering both the cultural and functional dimensions of public spaces in the city of Blida. The index was translated into a mobile application that allows participatory, real-time data collection and visualization tool. \n \tThe app was co-designed by the researcher (an architect with experience in communication and graphic design) in collaboration with a phone developer. After trials and adjustments, the prototype was launched on Google Play. A team of trained young female architects led a five-month field data collection campaign across Blida. A follow-up focus group with the data collectors was conducted to reflect on field challenges, propose improvements to the assessment tool, and identify distinctive patterns in women\u2019s urban experiences.\n \tThe challenges acknowledged, not as weaknesses, but as valuable feedback to refine the collaborative mapping tool. The presentation will outline the development process of the Madinatouha app, share insights from the collected data\u2014analyzed using Microsoft Excel and ArcGIS\u2014and highlight key lessons from this collaborative approach to mapping women\u2019s experience in public spaces.  \n \tOne of the project\u2019s strengths lies in its capacity to generate a wide range of maps and charts, showing the significant importance of participatory mapping and Geographic Information Systems in providing real-time and accurate data about public spaces from a user's view. This participatory method offers a practical pathway for urban planners and decision-makers to better reflect public spaces design.\nThe fieldwork revealed several challenges: unreliable internet connections disrupted real-time data entry; the time-consuming nature of assessments; cultural sensitivities around privacy; varying perceptions of safety; and occasional risks such as phone theft in crowded markets. \nThe focus group recommended involving urban planning institutions and architectural firms in future iterations of the tool. To improve data reliability, it also proposed combining expert evaluations with user input. The project continues to evolve, with the aim of developing a more sustainable and interactive model for mapping women\u2019s experiences in public space.\n \tThe project is believed to foster greater community participation and influence urban policies to be more responsive to women's needs.

Poor waste management, especially open dumping, contributes to environmental degradation, disease transmission, and emerging health risks from microplastics. Despite the UN\u2019s call to end unsafe waste practices, effective and inclusive management systems remain critically underdeveloped\u2014particularly in Sub-Saharan Africa, where less than 50% of MSW is collected and about 70% is openly dumped. In East Africa, Tanzania\u2014and especially its commercial capital, Dar es Salaam\u2014stands out as a hotspot for mismanaged plastic waste. The city generates approximately 4,600 tonnes of waste daily, yet less than 40% is collected, with the remainder being illegaly burned or dumped to later accumulate in streets, drains, and rivers, including the heavily polluted Msimbazi River, a major contributor of plastic waste to the Indian Ocean.\n\nTo address the lack of reliable data on urban waste accumulation, we present a city-scale, open-data-based approach to map visible MSW in Dar es Salaam using deep learning and street-view imagery (SVI). In close collaboration with OpenMap Development Tanzania and HeiGIT, we developed an open-source end-to-end workflow that involves collecting, annotating, and processing 360-degree SVI across 41 wards, training a deep learning classification model to detect solid waste, and generating a high-resolution MSW pollution indicator. This approach provides actionable spatial insights to optimize urban cleaning strategies, reduce health risks linked to water contamination, and support evidence-based planning for more sustainable waste management.\n\nThe Street-view imagery was collected between throughout  2024 by OMDTZ using a Bajaj tricycle equipped with a GoPro Max 360\u00b0 camera. This data collection effort covered major roads across Dar es Salaam. The imagery was made publicly available on Mapillary to enable open access and collaborative research.\n\nTo identify visible waste in street-view images, a two-step image annotation process was implemented using the open-source tool MapSwipe4Web for. Additionaly to manual labeling, we opted for Crowdsourced Pre-labeling: The MapSwipe community reviewed street-level panoramic images and flagged those containing visible waste.  All positively labeled images were manually reviewed by the authors to ensure quality. Further manual labeling was conducted, particularly for underrepresented classes.\n\nImages were annotated into the following three main classes: Waste Piles: Defined as accumulations of waste with horizontal and vertical extent, often indicative of illegal dumping or unmanaged MSW. Trash Bags: Properly packaged waste (typically in plastic or paper bags) that appears to be ready for collection. No Trash: Images with no visible waste.\n\nTo ensure spatial representativeness and reduce redundancy, images were sampled approximately every 10 meters along one-third of the road segments in each ward. In total, over 40,000 360\u00b0 street-view panoramas were annotated. Due to the computational and geometric challenges associated with high-resolution equirectangular imagery, each panorama was segmented into 12 overlapping patches. This approach reduced computational load, minimized distortion effects, and maintained spatial context for classification. Further labelling on the image patches resulted in a final training dataset size of 7378 (with augmented 29605) waste images and 7640 (27410) no waste images for the trashbag model and 1818 (7325) waste images and 1920 (6965) no waste images for the waste model. A classification-based approach utilizing the YOLOv11 architecture was employed to detect visible waste, as it significantly reduces annotation effort by eliminating the need for bounding box labeling. This method was used because conventional object detection offers limited practical benefits and introduces unnecessary complexity to the annotation workflow.. The resulting models demonstrated strong performance, achieving precision scores of 0.87 for trash bags and 0.98 for waste piles, and recall scores of 0.86 and 0.98, respectively. \n\nNevertheless, some limitation need to be considered. For instance, the model occasionally struggled to distinguish between visually similar objects like trash bags and plastic buckets or plastic tarpaulins. For waste piles, materials like rubble or patterned floor mosaics sometimes led to misclassifications..\n\nWe deployed the trained models across the entire city, processing a total of 500,000 panoramic images covering 1300 kilometers of road network. The results were aggregated onto a hexagonal grid to produce a spatially explicit indicator of visible waste pollution. This analysis was further complemented with UAV-derived observations of waste piles along the Msimbazi River\u2014a region largely inaccessible to ground-based street-view imaging\u2014yielding a comprehensive waste pollution map for the entire study area.\n\nUsing this workflow we can show that there are several hotspots of waste pollution in Dar es Salaam mostly located in densly populated informal settlements, while the wards along the coastline show only little waste pollution. Combining the created data with data from OSM, it was recognised that there is a lot of open waste in the immediate vicinity of the drainage system, which can lead to a higher risk of flooding due to clogging. \n\nOur results show the value of street view imagery for open mapping in OpenStreetMap and beyond. The extensive SVI of the entire street-network provides possibilities for other future usa-cases to enhance OSM like building material, blockage of drainage canals, road surface, etc.\n\nThe source data, code, and resulting datasets are publicly accessible, and the entire workflow is transferable to other geographic regions. The required resources are relatively low-cost, and open-source crowdsourcing tools, such as MapSwipe, can be leveraged to efficiently generate comprehensive datasets for model training.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "TZCRJU", "name": "Levi Szamek", "avatar": "https://pretalx.com/media/avatars/TZCRJU_d8FXjoZ.webp", "biography": "Hi im Levi,\nI did my Msc. in Geoinformatics at the University of Heidelberg, Germany.
