What we have is good enough, and there are options for everyone. But 15 years on, the same problems persist in OSM: while it's very easy to draw things, to add a road, a building, or an amenity, updating the map is so hard virtually nobody does that for free. That can only be fixed by tailoring editors to the task, because general-purpose editors cannot help. That is the future: thematic editors. In this talk we'll take a look at existing specialized OSM editors, like OSM Contributor, MapSwipe (I know), or StreetComplete. We will also note when an editor doesn't need a map to operate. And finally we'll imagine a few editors that could simplify maintaining the map, both on desktop and on mobile. The speaker, Ilya Zverev, has made the well-known Level0 editor which doesn't need a map to function, but also isn't strictly a thematic editor. Recently he's made a Telegram bot for a POI directory, which also featured an optimized POI editor. It enabled Ilya to collect ~500 shops and amenities in 10 days, and to keep the data recent. It didn't provide an interactive map, obviously.

Based on this use case, we started enhancing the OSM data using GPS probe based detections and satellite imagery. After the success we saw with the ETA and routing quality that we could achieve with OSM in Singapore, we started dabbling with the idea of piloting Navigation quality maps on OSM. Our journey on this started with researching the local traffic rules, signboards and restrictions that are relevant for Navigation. As Singapore is one of the countries in SEA which is well marked with all signs in SEA, we then moved on to solve the next level of challenge which is adding street level imagery across the country with the help of different cameras we could lay our hands on for the pilots. At times we used mobile phones with KartaView app and others we managed to add using better quality Go-Pro like cameras. Few interesting learnings along the way; Rain can play a spoilsport to your plans at the last minute; Government, building authorities would need time to give you permits for collecting imagery and you will need to plan those into your collection efforts; Roadworks, Road closures, congestion do not let you cover all streets fully. Despite all the planning, sometimes you may not get permissions, Eg: Private condos. For such situations, you can work with the local community to help add more imagery. Interesting learnings while mapping Singapore: Tunnels, Underpasses, etc. criss cross on multiple levels. Oftentimes mappers get confused, despite the availability of imagery. Road name abbreviations are sometimes not standardised and will have inconsistency when showing on maps. Maps are never perfect even in a well mapped country like Singapore as the physical world around you is changing. Instead of trying to be perfect, you can aim to be very agile and responsive, making the real world changes reflect in the map data as close to realtime as you can get. What can help you in doing this well is working closely with local transport authorities (SLA, LTA, etc. in case of SG); Other major realtors and establishments which run several malls, office buildings, tech parks, etc. And last but not the least - community. Both the OSM community and our driver partner community helped us immensely here. The journey to making the map for Singapore was quite arduous and needed the continued support of OSM community mappers, driver partners, local map operations teams. Everyone constantly keeping the map updated and improved helped us make the navigation to be best suited for the needs of Grab driver partners. We engaged these communities through various activities such as Geo*Stars, mapathons with organisations such as GeoWorks and hosted in-house mapathons to enable understanding and contribute to the amazing OpenStreetMap data. For our driver partner community, we started off with a whatsapp group to gather feedback and then proceeded to an in-app collection mechanism to make this reporting of road updates, map changes, a lot faster and seamless. This coupled with our on-ground map operations teams which run road tests of the navigation helped us ensure our map stays as updated as possible. Working closely with the community ensured that they also could see the impact they were making on the maps every day. This made Grab Driver partners to like Grab Navigation even more as it empowered them to build it together with us. This journey doesn’t end here, and we will be working even more closely with the community across South East Asia as this is the best way to scale these efforts on building maps for everyone.

CartONG is one of the implementing partners for mapping and information management (IM) projects of the UNHCR, a UN agency dedicated to protect refugees, forcibly displaced communities and stateless people. Getting data on refugee sites has always been a challenge given their fast evolution and the diversity of situations around the world. Therefore CartONG has been promoting OpenStreetMap as a complementary resource and sharing platform to produce accurate and recent data that can complement UNHCR’s existing database while also benefiting other actors (in particular local ones). From remote mapping to OSM-based analytical tools for decision making, CartONG would like to share its experience on building and implementing step by step since 2017 an overall strategy to support humanitarian response in refugee sites with UNHCR. We will focus on specific technical challenges, like dealing with accurate and precise data on a large number of sites at world scale as well as at site level. The implementation is still ongoing and the strategy also evolves as it moves forward to better fit the requests of the partner as well as evolution of the OSM landscape: we will present where we stand and what is planned for the next steps. Step 1/ Improve the consistency of the refugee sites’ tagging model on OSM (wiki documentation/ mapping data model) Step 2/ Promote refugee site mapping on OSM (training/mapathons/data integration/ cooperation among actors) - Improve the availability and quality of OSM data on refugee site around the world - Facilitate contribution and use of OSM data. Step 3/ Build a dedicated OSM replica for UNHCR specific use cases Step 4/ Monitor activities on OSM camp mapping - Complement UNHCR’s database and compensate for lack of data on specific sites. Step 5/ Generate a specific map rendering Step 6/ Feed a web application for spatial analysis - Create analysis products (including maps, sector indicators visualization, etc) using OSM as well as other data sources, and make them available to UNHCR’s team and other actors for field operations PUBLIC CONFIRMED Talk https://pretalx.com/sotm2021/talk/XLDXW9/ Track 1 - Talks Martin Noblecourt Manon Viou Olivier Ribiere PUBLISH TPKBQ9@@pretalx.com -TPKBQ9 MapaTanda: Mapping for and with the Ageing Population en en 20210709T121500 20210709T123500 002000 MapaTanda: Mapping for and with the Ageing Population In a nutshell, MapaTanda seeks to improve both the quantity and quality of data in OpenStreetMap that is important and relevant to members of the older adult and ageing population (60 plus years old) in the Philippines. This involves adding and cleaning features in OpenStreetMap such as nursing homes, hospitals that provide specialized care for the elderly, retirement homes, local offices for senior citizen affairs, community centers and other facilities that cater to or provide perks and services to older adults, etc. These data can then be used by local and national organizations for policy-making, planning, and implementing projects and interventions. SmartCT's goal as an organization is to put citizens and data at the heart of developing smart cities and communities in the Philippines. We believe in an open, inclusive, holistic, and citizen-centric approach to building smart solutions. To do this, we partner with actors such as local government units to ensure that they have access to quality open data that they can utilize for planning their programs and services. We believe in the power of open data and consider OpenStreetMap as a great amplifier of that power. This talk will focus on community building and openness as foundations of age-friendly cities and communities. Our main goals for its talk are below: 1. Recruit new OSM volunteers 2. Engage the older adult population to contribute in OSM 3. build stronger relations with the local and global OSM community as well as foster partnerships with more local government units and national agencies. 4. call to institutionalize openness through policies PUBLIC CONFIRMED Talk https://pretalx.com/sotm2021/talk/TPKBQ9/ Track 1 - Talks Kris Libunao PUBLISH ZVL93H@@pretalx.com -ZVL93H 3D Rendering with OSM2World en en 20210709T130000 20210709T132000 002000 3D Rendering with OSM2World The mission of OSM2World is to build a realistic 3D representation of the physical world using open data and open-source software. This is made possible by two trends: The increasing level of detail captured by the OpenStreetMap database, and the growing availability of open technologies for high-quality 3D rendering. Creating 3D models from OpenStreetMap wouldn't be possible without the impressive effort of the mapper community. One of the goals of OSM2World is comprehensive support for the rich landscape of tagging, such as Simple 3D Buildings and Simple Indoor Tagging. Besides the outside and inside of buildings, the rendering displays lane mapping for roads as well as a large number of other OSM features – likely more than any other open-source 3D renderer. In addition to the ongoing work to support a larger share of the OSM data model, OSM2World is being updated to make good use of modern technologies, including physically based rendering (PBR), the glTF format, and WebGL. These make it easier than ever to export visually appealing 3D models for use in many modelling tools or engines, and to display them on the web. This talk introduces the capabilities of OSM2World, with a particular focus on features which were added recently. As such, the session is intended to be suitable for visitors learning about OSM2World for the first time as well as those interested in staying up-to-date about new developments.

For this talk, I want to combine both worlds and discuss: * 0) How OSM already today is beneficial for the privacy of OSM consumers? * 1) Which personal data is in the OSM public database (spoiler: behavioural data of contributors)? * 3) Which potential privacy risks stem from the data for OSM contributors? * 4) What are the GDPR compliance issues? * 5) What is the outlook? I open the discussion (Q&A) with some ideas to mitigate privacy risks. They involve likely changes to the current data governance, OSM database structure and OSM data itself. Problems that are already evident that I plan to mention: 1. transparency on the processing of personal data of contributors 2. tracking of contributors, e.g. via - [https://resultmaps.neis-one.org/oooc](https://resultmaps.neis-one.org/oooc) - [https://overpass-turbo.eu/](https://overpass-turbo.eu/) with search "user:username" - [https://hdyc.neis-one.org/?username](https://hdyc.neis-one.org/?username) 3. sharing of OSM data with third parties, see [https://wiki.osmfoundation.org/wiki/Registered_data_controllers](https://wiki.osmfoundation.org/wiki/Registered_data_controllers) For the purpose of the discussion, I want to introduce the audience to a few core data protection concepts: - purpose limitation - data minimisation - definition of personal data in the GDPR - concept of anonymous and pseudonymous data PUBLIC CONFIRMED Talk https://pretalx.com/sotm2021/talk/RJZRZ8/ Track 1 - Talks Robert Riemann PUBLISH QUHKNR@@pretalx.com -QUHKNR Boundaries, Places and the Future of Tagging en en 20210709T154500 20210709T160500 002000 Boundaries, Places and the Future of Tagging Nominatim is the search engine that powers the search box on the main OSM site. One of the fundamental steps of preparing OSM data for searching is the extraction of information about their location, commonly known as their address. This is not a simple task because OSM data is much less structured than traditional databases and many users revert to using external data for this reason. However, the data is there and should therefore be usable. In the course of the last year the address algorithm of Nominatim received a major overhaul to improve how addresses are generated from OpenStreetMap data. The first part of the talk introduces the new algorithm and how it came to be. We'll look into the current state of tagging of boundaries, the problem of the urban/rural divide and the difficulties of country-specific mapping. The second part of the talk deals with the more general question what the evolving tagging schema of the OpenStreetMap database means for data users. The free-form tagging is one of the big strengths of OpenStreetMap. But the lack of rules does not necessarily have to mean lack of order. Using the example of address extraction, I'd like to discuss the future of the tagging schema from the point of view of a data user.

It tries to be just as simple as StreetComplete while offering per-topic views and presets just as MapContrib. In this talk, I present the editor I've made. I will talk about the editor itself, how it grew in the past year and a half, some technical background and give some statistics on edits made with it and which themes proved to be interesting. I'll also touch upon the possibility to create your own theme (but I'll do an Q&A-session specifically for that). Furhtermore, a comparison with other editors in the OSM-ecosystem will be made and differences with StreetComplete and MapContrib will be highlighted, as those two editors were key in inspiring this editor - yet there are some important differences with MapComplete in it's goals resulting in a fundamentally different approach and different use cases. I'll also zoom in on how the user journey is and how a few small features become available when the time is right for them to appear. Finally, I will have a look to where MapComplete could be headed and which projects and technical innovations will be made in the future.

Makina Maps is new Vector Tile Server build using Docker and based on Imposm, OpenMapTiles, TileServer GL and NGINX. The stack can be easily and quickly set up. The components allow to import OSM data into a Postgres database and server tiles on request. The tile caching is included. Using Imposm the OSM data can be update and the tiles cache invalided. This stack can be used as tile server for on request query and support fast update after many improvement was done and still in progress to OpenMapTiles. Fist, it requires to speed up the OpenMapTiles data layers query to server pretty quickly new tiles while users browsing the map. Secondly, it need to be able to update the database as fast the OSM diff update are coming and without locking the database. In complement of building and serving vector tiles, Makina Maps can hosts vector tile styles and is able to build and server raster version of these tiles. There is also the possibilities to server stored tiles from MBTiles like raster or eg. RGB dynamics light hill shading.

We found significant issues that impact auto navigation, and variance depending on past editing activities of the community and corporate members in each country. We began our work in each place in conversation. Sometimes we were met with friendliness, other times skepticism. We learned to respect local language conventions, which sometimes meant using machine translation, and this did help greatly. The preferred and active communication channels varied as well, from mailing lists, to forums, to IRC and Slack, to the Wiki and GitHub issues. For documentation, we took an “all of the above” approach, making sure to reflect adaptations in approach in all the spaces. Technically we worked on 10 categories of mistakes: crossing highways, crossing highway bridges, impossible angle, island highways, impossible oneways, mixed layer and 4 categories connected with turn restrictions. We used all available ground truth sources to determine if an edit was needed, and tracked those edits with a changeset comments hashtags for our team and each country. So far we have reviewed more than 26,000 issues and fixed almost 55% of them. Hoping that this is just the beginning of coordination with communities and the Data RAVE team.

Coastal communities are among the most vulnerable and face a range of unique flooding hazards including storm surge, wave impact, and erosion causing damage to homes, businesses, and infrastructure. Timely emergency response relies on high quality spatial datasets to support 911 calls, disaster planning, and response & recovery efforts. It is imperative that road network and water feature (ocean and inland) quality be as accurate as possible when used to support emergency operations. Our team has selected a few coastal cities to run a subset of relevant map error checks to identify the location and density of key errors that would impede response activities. With these data our team uses the Map Quality Measurement process to generate a heat map and narrow down the most problematic areas for communities to focus and improve data.  Map Quality Measurement (MQM) is an analysis and visualization tool revealing the distribution of errors within a given geography. MQM works by running a series of checks, referred to as Atlas-checks, that identify geometric, topologic, and attribution errors. Atlas-check outputs show the density of data errors, the types of errors they are, and assign priority to critical fixes. The checks are written to review core map features such as roadways, buildings, waterways, coastlines, and their relationships with one another.

Another aspect that can be evaluated as well as the data coverage. This analysis aims to evaluate how's the good coverage of OSM data, whether OSM has been covering all the area, specifically on the road network data coverage. A good map data ideally can cover the whole area. Thus, the results from this analysis, hopefully, could help the mapper to get an insight into the quality of OSM mapped road network data and identify where are the unmapped areas. There are two methods offered in this analysis. First, OSM data will be compared with the official road network data from a trusted source, such as a dataset released by the government. Second, OSM road network data will be compared with the population distribution to know whether all the populated areas have access to the nearest road network. In the ideal world, all populated areas should have close proximity to the road network, ensuring them having access to public services such as transportation and public facilities. The closer population to the road network, the easier it is. The analysis will be using open-source GIS software, which is QGIS, and a publicly accessible dataset.

This panel will discuss ethical issues that should be considered while mapping with and for communities living in vulnerability. Potential lines of inquiry for the panel will include: What is the best practice around balancing a need for good and quick maps and the potential for exploitation? How is ethical mapping with vulnerable populations the same or different from responsible data, or other kinds of ethical frameworks? Who participates in the planning and execution of mapping exercises in vulnerable locations, and who decides who should participate? Who decides what is important, and whose voice is left out? How do we obtain consent from a community, and who provides consent? Who controls the use of information? Who owns the output, the maps, and the resulting data? What is left with those who generated the information and shared their knowledge? In whose interest are projects in vulnerable locations conducted? How do we address privacy concerns related to the use of aerial and satellite imagery, and how can we prepare vulnerable communities? How can we be sure that the benefits of our mapping will outweigh the risks or harms? Questions are from “The GeoEthics in Vulnerability Principles” document.

Experts estimate that only 2-5% of OSM contributors are women. The results of the 2021 OSM Foundation survey starkly remind us of the drastic gender gap within the project as well as the vicious sexist, racist, and white supremacist attitudes that exist among some individuals within the “community”. While it may be convenient to believe that data are neatly objective packets of information, and that an edit to OpenStreetMap is the same no matter the gender identity of the editing person, countless historical and present-day examples provide clear evidence that data cannot be decoupled from human bias and perspective. At the same time, it is highly encouraging that courageous and innovative groups and members of the OSM community have taken bold steps to increase the participation of women and other minorities. Panelists will discuss how structural inequalities and individual instances of sexist and misogynistic language and behavior present significant barriers to women’s participation. Women experience these inequalities differently depending on their context, privilege, and background, and the panel will address these issues from an intersectional lens. Panelists will also recommend steps that organizations, boards, communities, and individuals can take to be anti-sexist members of the OSM ecosystem.

The plan was to do this together with French organization “Les Libres Geographes” who are experts in this topic. Due to Corona, we were not allowed to enter the city and had to think of a plan B. We will show in this talk how a local team can do the collection of necessary data and how a remote team can do the mapping – organized by a regional partner who at least is nearby. We show how both sides could benefit nearly as much as if we had been there, and why this is in times of CO2 reduction and pandemic might be a wise choice for other cities and mapping projects as well. But we also show the limitations, for example that this would not have worked without a minimal preparation of the local people during the last years.

Our ethos is to “map reality”, and our approach is incremental – one person might trace something from aerial imagery, another person might add a street name from their own local knowledge, and a third person surveys and records a speed limit on a visit to the area. Many paths, trails, and streets have access restrictions that may not be apparent from aerial imagery. These could range from oneway traffic rules to restrictions on certain types of vehicles, to “no dogs allowed”, or something could be entirely private, or in a military danger area. End users of OpenStreetMap based services are often insufficiently informed about access restrictions, leading to a rising number of complaints from land owners or otherwise responsible individuals, and frequent requests to “immediately remove from OSM” a certain object. This can either be due to missing access restrictions in OSM, or due to existing access restrictions not being correctly interpreted by the platform using OSM data. This talk intends to take stock of the current situation in OSM and major data-consuming apps, and make some recommendations aimed at both mappers and data consumers in order to reduce the risk of leading users down the wrong path. The author is a member of OpenStreetMap’s Data Working Group which handles incoming complaints. PUBLIC CONFIRMED Talk https://pretalx.com/sotm2021/talk/GEKXWL/ Track 1 - Talks Frederik Ramm PUBLISH W7FP3J@@pretalx.com -W7FP3J Collection and use of data about entrances of buildings en en 20210710T113000 20210710T115000 002000 Collection and use of data about entrances of buildings True door-to-door navigation requires us to accept that people don't really visit housenumbers, they visit amenities and apartments via specific building entrances. The significance of this difference varies and is greatest in cities with unoptimal address schemes, for people with accessibility needs and for delivery drivers quickly visiting lots of unfamiliar recipients. City of Helsinki in Finland uses OLMap to take photos of each entrance to a building, to correct the GPS location of the entrance, to record the address and other properties of the entrance as well as to facilitate mapping this information and the access paths in OSM. Last year, the city employed some secondary school students as mappers. Over 6000 images including 5762 entrances, 1767 flights of steps, 645 barriers and 241 info boards were contributed to the 30000 entrances mapped in Helsinki. A new batch of students will be employed this summer. Using Gatesolve, delivery drivers can take advantage of the address, entrance, and accessibility data collected and mapped in OSM. To limit visual clutter, the app includes zoom-dependent cartography of the entrances. The search finds entrance-level addresses and the routing function visualises any steps and barriers on the way to the entrances. An entrance typically doesn't have a unique housenumber, so it's important to also map tags such as "addr:unit", "addr:flats" or "ref" when appropriate. When these are not available, the different entrance types, access values etc. can help distinguish between entrances. If a path without stairs has been mapped through to an entrance, we assume there are no stairs, but if there is any gap between the path and the entrance, we communicate uncertainty. Entrances inside as opposed to along building outlines cause troubles for us. For example, there are entrances inside building passages and under hanging roofs. Mapping these entrances along "building:parts" can clarify this, but it's disproportionately laborous as well as prone to topological mistakes which result in inaccurate cartography. We continue to develop the apps. For instance, all the mapping this far has been done in the iD editor, but custom mapping functionality may be necessary to feasibly support explicitly linking amenities to corresponding entrances via the proposed "associated_entrance" relations.

It consists of participants such as hobby cartographers, academics, local governments, university student clubs and local NGOs. According to OSMstats, the community, which has an average of forty active mappers daily, has added more than 1.3 million buildings and more than 200,000 km of highways to the OpenStreetMap since 2018. Active OpenStreetMap contributors identify community problems and needs are listed as following; language barrier and the inexperienced local community. According to the EF English Proficiency Index, Turkey ranked in 79 out of 100 countries/regions. Lack of having OSM documentation in Turkish is one of the biggest barriers to growing a mapping community in Turkey. Insufficient OSM documentation in Turkish adversely affects participants of all levels. It causes a lack of technical knowledge about OpenStreetMap data structure among experienced mappers. Even if they make an outstanding amount of contribution, it can cause a decrease in data quality. From the newcomers' point of view, it significantly reduces the pace and motivation of learning. In order to tackle these problems and needs, Yer Çizenler and Youth Season NGOs are teamed up and kicked off the Open Source Volunteering Programme. The main goal of this programme is building and enlarging the OpenStreetMap Turkey community. The objectives of this programme are to train volunteers to get to know more about OpenStreetMap, to translate OpenStreetMap related documentation and tools and to map unmapped towns in Turkey. This programme consists of three phases; training, translation of OSM tools and mapping unmapped towns in Turkey. 8 OpenStreetMap training, four mapathons, three online public experience sharing events and 18 weekly meetings were organized during the programme. Twenty volunteers were selected to be part of the Open Source Volunteering Programme. These volunteers were trained on the following topics; fundamental of OpenStreetMap, OSM data model, OSM tag schema and OSM editing tools such as iD Editor, JOSM, Vespucci, GoMap! and RapiD. With the workshops and hands-on webinars, the participants got familiar with OSM data structure and gained the ability to use OSM editing tools. Additionally, the Open Source Volunteering Programme helped the Turkish OSM community to be connected with international OSM communities to learn from their experiences. As an example, we hosted Geoffrey Kateregga, Community Programs Manager at HOTOSM shared his learning and valuable community growth experience in Uganda as well as in Africa (1). As the second phase of this program, the volunteers translated OSM iD Editor Vespucci, MapRoulette and uMap tools into the Turkish language. In the third phase of the programme, volunteers mapped 120 unmapped towns in Turkey. Unmapped towns are exported from Pascal Neis's Unmapped Places of OpenStreetMap (2). These towns are mapped as points but do not have any roads in a radius of 700m. The MapRoulette and OpenStreetMap iD Editor are used to map unmapped towns. MapRoulette task was used to coordinate collaborative mapping efforts and monitor the progress (3). As a result, 11.838 map changes were made by 15 mappers. There are 10.295 unmapped towns in Turkey. As Yer Çizenler and Youth Season NGO, we're aiming to enlarge the active OpenStreetMap Turkey community and complete a map of unmapped towns in Turkey by the end of 2021. Overall, this talk will highlight key elements of building and enlarging OpenStreetMap communities in developing countries and learnings from Open Source Volunteering Programme. The proof of concept of mapping unmapped towns methodology will be shared with other communities to encourage them to implement similar activities in their local community. * (1) [https://www.youtube.com/watch?v=fD4fvmJ3Wmk](https://www.youtube.com/watch?v=fD4fvmJ3Wmk) * (2) [https://resultmaps.neis-one.org/unmapped#5/47.100/9.800](https://resultmaps.neis-one.org/unmapped#5/47.100/9.800) * (3) [https://maproulette.org/browse/challenges/15901](https://maproulette.org/browse/challenges/15901) PUBLIC CONFIRMED Talk https://pretalx.com/sotm2021/talk/EHQ7GH/ Track 1 - Talks Said Turksever Oğuzhan Er PUBLISH ZLK9X9@@pretalx.com -ZLK9X9 Lightning Talks II en en 20210710T130000 20210710T132000 002000 Lightning Talks II ## The Boundary Puzzle *ark Arjun* | *[arkarjun](https://www.openstreetmap.org/user/arkarjun)* The story of OSM Kerala community in developing the administrative boundaries of Kerala, a southern state of India. The Mammoth effort of volunteers made the different level of administrative boundaries of the state created a large impact in recent times including the pandemic management.

The simple interface could make it appear that the technical implementation is equally simple. It is maybe a common misconception that things that look easy to the user are also lighter in terms of code complexity. But under the hood, it is anything but. For example, amongst other things, the app has a unique way to avoid and to automatically resolve conflicts when uploading data to OSM. For an app that promises its users to work completely offline and thus automatically stores unsynced edits for any duration before upload, this is very useful to have. Furthermore, it comes with the ability to undo edits in any order (not just the last) and even undo most edits after they have been synced with OSM already. This talk shall give you an architectural overview over how StreetComplete enables its users to do these things. It could serve other editor developers as inspiration, however, most technical concepts in this app are probably not well applicable to be used in a general OSM editor, as StreetComplete vastly limits its users what they can do and therefor we can make certain assumptions about how the app is used.

Since 2006 it is used to import OSM data into PostgreSQL/PostGIS databases for rendering and other uses. In the last years there have been a lot of improvements to osm2pgsql. With the new "Flex" output, osm2pgsql is now much more versatile which allows new applications. The talk will be about the new developments in osm2pgsql und show how to use the new features. Osm2pgsql is used for rendering bitmap tiles for many maps, including the main OSM map and many others. But it can also be used to import OSM data for generating vector tiles and for many other use cases. It is now possible to tell osm2pgsql exactly what output tables with what fields to create in the database. Transformations from the OSM tags to more or less any format you need in your database can be defined in Lua code. Together with the powerful SQL query language in PostgreSQL and the geometric algorithms in the PostGIS plugin, this makes all sorts of analytical processing possible. Osm2pgsql can be used to import small OSM extracts quickly for one-off processing or run a minutely updated planet-wide database on a reasonably-sized machine making OSM data processing accessible for everybody.

As a member of that group, I noticed that the awareness of OpenStreetMap and OpenData is very low in this group and in Ireland in general. One of the excuses often given by these groups is the demographic which is less computer literate than my generation. However, after uploading a few OSM tutorials onto YouTube, I received good feedback and two female acquaintances of that age group started actively contributing to OSM. Motivated by those developments and by looking for something productive to do during the third COVID lockdown, I started a YouTube tutorial series on OSM, uMap, overpass turbo and fieldpapers to show the benefits of OSM to historically interested individuals and groups. Within only a few weeks, I had gathered a small following and continue getting positive feedback from people who discover OpenStreetMap for their personal or group projects. I believe that giving the public concrete application examples of OSM rather than trying to convince them by dropping terms like OpenData and OpenSource into the conversation, is a way to promote OpenStreetMap to an audience that is keen to learn and to apply the knowledge. It is a time consuming process, but necessary for a shift in awareness about OpenStreetmap.

This is how the MapLibre was born. As a group of individuals, we coordinate the effort and synchronize contributions from multiple teams (MapTiler, Amazon, Facebook, Elastic, Stadia, Microsoft, Jawg, GraphHopper, Toursprung, etc) - working on JavaScript and Native code implementation of the renderers and related ecosystem. Multiple releases have been published, the project has CI checks for contribution, regular steering committee meetings, updated support for TypeScript, several bindings such as ReactJS, the Metal rendering on iOS is implemented (as Apple decided to deprecate OpenGL ES), and many issues and bugs has been fixed. There is plenty of ideas what to do next - from implementation of 3D terrain rendering, to support of non-Mercator map projections, or tighter integration with Leaflet, and much more. Let's explore the current status of the project, learn how to use MapLibre in your own software with practical code samples, and how to join and contribute to the collaborative development and participate on a shared roadmap.

The experience for the end consumer has continued to improve, with better map data, more intuitive interfaces, and greater portability. A lot of the developments have focused on in-car navigation, with Google Maps, Apple Maps, HERE Maps, and TomTom dedicating significant resources to the space. Even in our beloved OpenStreetMap, vehicle based navigation claims centre stage. In this presentation we’ll explore the state of pedestrian data in OpenStreetMap, how it differs between cities, why it’s important to think about, and how we might collectively improve the quality of pedestrian data. To begin with, we’ll take a look at data downloaded with Overpass Turbo. The data represents nodes, ways, and areas with pedestrian relevant tags such as highway=footway and sidewalk=both. Our analysis focused on five cities with differing characteristics: - Folsom, USA - Heidelberg, Germany - Melbourne, Australia - Stone Town, Tanzania - Yesan, South Korea These cities differ in population, cultural characteristics, urban planning, history, and topography. We’ll explore what kind of OpenStreetMap tags have been used in each city, how close this matches the state of pedestrian infrastructure, and how the cities compare to one another. We’ll then look at some reasons why pedestrian data has been neglected including the limitations of satellite imagery, commercial incentives, and data collection methods. In the final part of the presentation we’ll propose and hopefully discuss some of the tools that could help including Mapillary, StreetComplete, GoMap!!, and Vespucci.

The OpenStreetMap Standard layer is one of the high profile OpenStreetMap services, but not many people know who uses it, and where. This talk covers the goals of the service, it’s history, how it's designed, and dives deep into how it's used. Using improved logging functionality, we’ll get answers to these questions and more. We’ll cover the policy and technical basics of the service, showing how changes make it to your browser through the various elements of the stack and what we set out to do by running the standard layer, including policy and history. Diving deep into the usage, we’ll look at where people are viewing, where they’re from, daily and weekly usage patterns, and then into what sites and apps people use to view the layer, including the long tail of small sites. You’ll see how different uses put different loads on the OSMF servers, and how load doesn’t come from where people think it is. Many people just want to see their edits on the map, and we’ll cover that too, looking at how they show up and what to do if they don’t. Along the way we’ll learn how to see your changes on the map and see heatmaps, treemaps, and find out just what’s up with the teapots.

Being one of the awardees for the 2020 Community Impact Microgrants by HOTOSM and Facebook, the OpenStreetMap community in Kenya ran a virtual three-month training program for women and girls interested in OSM. While the project was implemented towards the end of 2020, the ideation process began at the start of the year when discussing community health and brainstorming on activities to conduct virtually due to COVID-19 restrictions. This included carrying out a community survey, identifying gaps and challenges, and figuring out what next. Our key focus was community growth, especially in terms of diversity and membership. We had some virtual activities that introduced new mappers to the community but still saw no diversity improvement. We, therefore, designed a women-only training program that would run for eight weeks. We were able to train a group of 35 beginner-level and intermediate-level mappers on all aspects of open mapping. Activities included hands-on workshops, presentations, and mapathons. During this period, we had some successes, learned a lot, but we also had a good share of challenges. We hope that by sharing our experience, other communities interested in implementing similar programs can learn more about the same; we also hope to have discussions that would improve future iterations of the program.

This panel focuses on the challenges contributors face in building OSM communities in the South and the strategies they adopt to achieve their goals. It brings together active members of selected OSM communities who will share their experiences and make recommendations for building strong OSM communities. Contrary to the North, the South has many challenges to face since most of them are poor countries where people are in constant search of daily bread whether they are students or young graduates. It is therefore difficult to engage youth and even adults in volunteer work. Those who engage in volunteer work expect to earn a strict minimum of money, such as the cost of fuel to get to the activity site. Those who engage in local community building, however, must have little funds to pay for food and drink, to buy internet connection during mapathon activities or training. Nevertheless, some communities manage to move forward thanks to strategies set up internally. This panel will be an opportunity for us to talk about challenges in different countries and to share the strategies adopted by each side to inspire others. At the end of this panel, participants will be better skilled on how to act for strong and inclusive communities with engaged and empowered members.

Introduction (5 minutes): Brief Introduction of Panelists and their involvement in OSM, as quantified in existing work. This includes a very brief overview of paid-editing in OSM and how the scale has increased in recent years, along with the adoption of AI-assisted mapping, and any new datasets made available. This will be positioned within the results of the OSMF 2021 Community Survey and briefly discuss the distinction between corporations as data consumers and corporations as data producers. 2. Formal Panelist Introductions (5-8 minutes each). Each speaker will have a few minutes to describe their company's involvement in and use of OSM. 3. Moderated Discussion (40 - 60 minutes). The audience will have the chance to pose questions in a separate chat / shared document and the moderator will collate questions and ask the panelists. Example questions to the panelists include: - Why OSM? There were likely many possible platforms that your company considered, what was the reason for choosing OSM, and what was this process like? Was there immediate buy-in, or not? - If local volunteer mapping communities are active in the regions you are mapping, how do you communicate and work with them? Are you supporting them directly in any way? - How does your company intend to contribute to OSM? Is it in datasets? technologies? mapping expertise?

The quality of data added to OpenStreetMap is of high importance if we have to keep saving lives and all other things. Data quality can not be ignored, this is very much discussed on various mailing lists, channels and whenever we speak about OpenStreetMap, it is likely to be the first question we expect from our audience who had no idea about OSM in the first place.

This presentation will explore some practices in relation to contributing to OpenStreetMap and focuses on Ghana as the Area of Interest. It will demonstrate some of my observations in Ghana: * how they came about and how I will deal with them or have resolved them and; * how most of these can be improved and avoided in the future. At the end of this talk I hope to have convinced you enough to take full responsibility whenever you make a changeset; Quality or Quantity.

Having to maintain a rendering database isn't. That's where tilemaker comes in. SOTM 2021 will see the release of the [all-new v2.0](https://github.com/systemed/tilemaker) which makes vector tiles speedily, on your own hardware, without a database. Richard Fairhurst explains how it works and how you can use it. ## GeOsm: The first mapping data-based social network to connect and empower communities. *SOB Willy Franck* Our goal is to create a mapping data-based social network for territory stakeholders. We want to work with different actors of the digital ecosystem to facilitate the promotion of our tool to those who need it. And it will be up to each community to appropriate the approach in an innovative way to help states, associations, people, companies and the environment. ## State of The Map Africa 2021 *Sharon Omoja* | *[shazomojah](https://www.openstreetmap.org/user/shazomojah)* The State of the Map Africa conference celebrates the culture of open mapping, open data and GIS and its impact across Africa. In this talk we will give updates and plans for this year's State of the Map Africa conference. ## Presenting New Numbers: Quantifying the Increase in Paid Editing Since 2018 *Jennings Anderson* There are now more than 2,500 active _paid editors_ in the OSM Community. The last time we comprehensively quantified this editing activity involved just 1,000 editors across ten companies. This talk describes the increase in paid editing since 2018 with country-level breakdowns of editing activity and information regarding new editing teams and the growth of the existing teams. ## Tanga Buildings Import and Community Mapping *Antidius Kawamala* | *[KAWAMALA](https://www.openstreetmap.org/user/KAWAMALA)* This is an Initiative for scaling up the OpenStreetMap Project by addition of buildings footprint data for entire region of Tanga,Datasets was developed by Ardhi University Students (ARU) in Collaboration with Tanzania Communication Regulatory Authority (TCRA) in 2021. Furthermore, There are different community mapping activities as micro-works going on in the region, as the mission of enriching and making freely global spatial data as well as capacity building to the local community on how to use free and open source tools in contributing data to OSM. ## Activities performed by IRDP YouthMappers on 2021 *Shabani Magawila* | *[SHABANI MAGAWILA ](https://www.openstreetmap.org/user/SHABANI MAGAWILA)* [IRDP YouthMappers](https://twitter.com/irdp_mappers) is one of the Active Chapter available in Dodoma, under the supervision of the Institute of rural Development Planning - Dodoma.

Rasters, vectors, language and internationalization en en 20210711T163000 20210711T165000 002000 A new map renderer for OSM? Rasters, vectors, language and internationalization OSM's mission is to create a free, global dataset of geodata for diverse applications. A mainstream OSM use case is **web cartography**: the graphical display of geographic features on the standardized browser platform. Cartographers want to make beautiful, labeled, multi-resolution maps; maps need to be loaded progressively for a smooth user experience. The web map status quo centers around two distinct approaches. One approach, used by the OSM Carto project, is server-rendered raster map tiles displayed as images in the browser. Another approach is to use a WebGL framework that consumes tiles of vector features. In the first part of this talk, I will investigate the tradeoffs inherent in these approaches with regards to **multilingual text and internationalization**, as these pose limitations for localizing OSM applications to different languages and cultures. The second part of this talk will introduce new techniques and libraries for rendering OSM data that are a compromise between the raster and vector map ecosystems. I'll demonstrate some of these ideas in protomaps.js, a new Canvas2D and Leaflet-based open source map rendering library.

This is reason enough to compare the OpenStreetMap of then to the OpenStreetMap of now and to show how OpenStreetMap and the Overpass API have changed or not changed over that timespan. For this purpose I will present an overview: With which requests are the public instances of the Overpass API actually used? The Overpass API has been intended for compound queries for the public transit data model of OpenStreetMap, but actually got popular for the simpler tag queries on bounding boxes. The provisions for an area data type have never materialized. How has it protected itself and how does it now protect itself against excessive load? I have always been proud that the service runs on ordinary server hardware and nothing huge, but still can give every user a meaningful amount of computation time. The necessary measures to curb the greedy and the stupid have evolved over time. Which requests for features and questions have been addressed to me as the developer? Basically everything we use now has been requested by users of the service. Probably the best idea has been to change from the longish XML based query language to the now much shorter QL based language.

But it does not mean that they are not using it. I was talking with a pair of tourists using maps.me to navigate. They commented that OpenStreetMap sounds like an interesting project. But it seemed to them to be an unnecessary duplicate of maps.me with its great maps. They were completely unaware that all useful data displayed by maps.me is from the OpenStreetMap. OSM data can be used by anyone, with few requirements. One of them is requirement to clearly and prominently state source of data. Despite this, many companies somehow fail to include a proper attribution. Including ones that are incredibly wealthy and ones that put massive effort into designing their applications. How can we change that situation? Many people who would contribute are unaware that OpenStreetMap exists. We are losing potential contributors. Especially among people not interested already in open data and maps. It is one of reasons why demographics of OpenStreetMap are so diverged from overall population. One needs to be quite unusual to be even aware that it exists and that this data is widely used. Due to obvious conflict of interest between OpenStreetMap community and corporations using this data fixing this problem will not be easy. But we should try.

After first excitement, challenges starts to appear one after another: most of them originating from a need to create a rigid set of rules for the entire world, which is full of diversity due to the variety of nature. We also faced the challenge of lacking international standardization for hiking trails, which is unique for each country (and even on this level with many exceptions and specialities - like oneways, via ferrata routes or even climbing trails). And last, but not least, we have to dig all this information from the OpenStreetMap and turn it into a map understandable for everyone. We managed to create a layer with trails and corresponding points of interest, which can be filtered on hiking or biking in the customize tool. This layer can be overlaid on top of any map. However, we created a specialized map style which combines OpenStreetMap with contour lines and hillshade and highlights things you need for moving around in the nature. The schema of MapTiler Outdoor is based on the open-source OpenMapTiles (OTM) schema and data are processed using OMT stack. MapTiler Outdoor is available via MapTiler Cloud as a service or in a form of a data package for download.

It simulates car, bicycle, foot, and public transit traffic, and runs on Mac, Windows, Linux, and directly in the web browser. A/B Street allows the user to reallocate existing road space between cars, protected cycle lanes, transit-only lanes, and street parking. Users can also modify traffic signal timing and create access-restricted neighborhoods. Individual and aggregate results from the simulation can be compared before and after the changes, creating a simple way to evaluate potential changes. A/B Street has been designed for the general public to easily explore proposals for reducing dependency on cars. This talk will cover some specific cases in Seattle where the software has been used to propose real changes, like opening a shortcut through a gated community for cycle and foot traffic to avoid dangerous roads. We'll discuss how to start using A/B Street in your area, the challenges in finding other open data-sets required, and some options for how to publish results. Finally, the talk will briefly demonstrate how A/B Street's rendering can be used for validating some tags, and how to get involved with the project.

In this workshop, you will learn how you can use a variety of R packages that are ideal to: * acquire relevant OSM data in a vector format * clean and process the data * display it in static and interactive visualisations * share a visualisation with others * export the data to other programs for further editing Most data acquisition, cleaning, processing, visualising and exporting can be done writing an R script. For further refinement of an output, other point-and-click programs (like QGIS) might be required, but storing the bulk of the process in a script allows us to easily reapply the same process on an updated dataset, share the process with others so they can learn from it, and provide supporting evidence when publishing results. Basic knowledge of R is preferred to follow along this workshop. If you want to run the commands on your own computer and learn by doing, please install both [R](https://cran.r-project.org/) and [RStudio](https://www.rstudio.com/products/rstudio/download/#download) prior to attending, as well as the necessary libraries for spatial data processing (see [OS-specific instructions](https://r-spatial.github.io/sf/#installing)).

The focus of the discussion will be on explaining the design of the map and what cartographic and technical considerations stand behind it. The aim is for participants - both newcomers and experienced mappers - to better learn how to read the map, to better understand the cartographic and social challenges of designing a rich, global, real time updated map based on OpenStreetMap data for a truly diverse international and multi-cultural audience and hopefully to get some participants more interested in community map design and to encourage them to either contribute to OSM-Carto or to contribute to or start their own regional or thematic map design projects. Secondary goal of the session is for OSM-Carto developers to better understand where the map is difficult to read intuitively for the OSM community.
