Welcome to SotM 2020!

OSM Foundation board chairperson Allan Mustard offers his personal assessment of challenges facing OSM and how he thinks the community and the OSM Foundation Board could deal with them.

Last year, HOT collaborated with OSM Liberia and iLab Liberia to complete the mapping and perform quality assurance in four counties in Liberia. The objective of this program is to update OpenStreetMap data to assist with a Social Registry data collection in four counties in Liberia: Bomi, Bong, Nimba and Maryland. Buildings and roads are the entities to map for this program.

Drone technology is an evolving industry used in multi-disciplinary fields ranging from agriculture, marine conservation to real estate and films. There’s so much potential and possibilities on what drones could help people making work faster and more efficient. In mapping, aerial imagery uploaded to Open Aerial Map can be used as basemap for OSM editing. Example cases are in Batad Rice Terraces, UNESCO Heritage site for mapping tangible changes in the community over time and create a tourism map and other small urban communities in the Philippines, aerial imagery was used for mapathons and community mapping done in OSM.

The talk is to basically share the experience of working with Imports of Health Facilities in India (OpenGovernmentData). We planned to go briefly through the background of Open GovernmentData and the countries following the OGD, along with the compatibility of OdBL for the datasets they provide to the public.

The main purpose of the import is to provide accessible data of accurate health care information from the Open Government Data directories for Hospitals, Health facilities, Blood banks, Health Centers and Health Clinics information which can be useful for all the people and also the Humanitarian team in India.

The primary focus of the talk is the import process from data preparation to the execution which includesImports Guidelines , Data Cleanup, Data transformation, Data Execution. The talk shares the detailed stats of the - Indian Health facilities OSM map data coverage before & after Imports and our survey experience for collecting the health facilities records in our region - Telangana.

We also line up with the Survey experience to collect the Health facilities records and conducted OSM awareness programmes. Conclude the session with the future plan and local community support.

This talk will present an evaluation of different OSM routing software and its impact on the journey. Several popular OSM routing software results will be evaluated on its route-cost (distance and or time) and different modes of transportation (from walking to motor-vehicle). Additional evaluation on the ground will also evaluate which route is a good (or bad) one and what may cause this impact.

This talk is based on the experiences I faced while working with the public sector on mapping and try to identify some of the impacts that made and answering 3 questions which arise:
* How much Money should I spend?
* How much Accuracy do I need?
* How much Human Involvement?

Separation of features by their importance is a core technique in cartography.
But what happens if features of the same feature class (e.g. train stations)
have a varying importance? A manual cartographer can choose the important features
based on other knowledge. Howerver, rule based cartography which is dominating in
the OpenStreetMap environment cannot work this way.
A computer programme rendering a map needs selection rules. Someone has to
implement them.

This talk presents some examples showing how to add lacking relevance information
if the importance of features within one feature class ranges span between extreme
values. It will show how train stations and airports can ranked using other OSM data
and external datasets.

Crowd2Map Tanzania is a volunteer run crowdsourced project that has been mapping rural Tanzania since 2015. This talk will give an overview of some of the lessons learnt, particularly in building mapping communities in remote rural areas with first time smartphone users.

Lightning Talk session.

Mobile mapping is the process of collecting geospatial data from a mobile vehicle using a 360º camera, laser scanner, GPS/IMU positioning system, and other sensors. This is one of the most time and cost effective methods to collect geospatial data, but the required equipment can be expensive. An alternative approach to mobile mapping brings the opportunity to the OpenStreetMap community to "Map in 360" using a wide range of consumer devices compatible with Mapillary. Instead of capturing a frame of street-level imagery in a single direction, a 360º camera can capture the entire scene simultaneously. 360º street-level imagery provides the OpenStreetMap community a more comprehensive understanding of the map space and more accurate machine-generated map data. In this talk, we will review the workflow of data collection with 360º cameras, look at how to upload 360 street-level images to Mapillary, and compare the impact of different 360º camera models in terms of map data extraction accuracy. OpenStreetMap communities can use this knowledge to coordinate their own street-level imagery collection with 360º cameras to contribute to Mapillary and improve local maps.

This talk will present the results of a survey done on the State of the OpenStreetMap, the unique challenges and success of OSM in Africa and how the different communities are working together to grow the map and the community on the continent.

What are the perspectives and challenges around the new wealth of building data in OpenStreetMap?

Le Togo, l’un des plus petits pays de l’Afrique de l’Ouest abrite depuis 2013 une communauté OpenStreetMap. OSM Togo a mise en œuvre de nombreux projets mais a connu également des difficultés. Cette présentation a pour objectif de faire un aperçu sur la vie de la communauté OpenStreetMap Togo.

We built open-source infrastructure that allows the community to integrate open data reviews of POI into the OpenStreetMap ecosystem. This enables any application or website to make use of a reviews layer, and to benefit from the shared data pool that is created by a combined user base of participating applications. We built it to ensure that people all over the world can freely share their insights about things that matter to them without being confined to proprietary data silos.

Humanitarian Openstreetmap Team (HOT) is an international team focused on humanitarian action and community development through open mapping. Since 2010, the organization has managed activations to attend multiple events such as understanding hazards, public health, refugee response, among others. However, when we think about organizing large-scale efforts it can be complex, due to the necessary logistics, volunteers involved, and also assuring that the data collected is meaningful. MapCampaigner, is a tool which monitors progress, view metrics on the quality and completeness of collected data and users engaged. The goal of this talk is to present the latest features included in the latest update of the tool, the goals that MapCampaigner accomplishes and many humanitarian and non-humanitarian examples through a demo.

Current presentation aspires to contribute to an overall assessment of the OSM map in Athens, Greece. The OSM content is assessed in terms of completeness and precision. Various official mapping sources and ground truth data are employed in order to measure the current state of the map.

When people come to OpenStreetMap for the first time, their expectations are sometimes at odds with what the OpenStreetMap community is doing. If you have been puzzled by an OSMer telling you that OpenStreetMap is not a map, that openstreetmap.org is not aiming to compete with Google Maps, or by their stubborn refusal to remove a private trail from the map, then this talk is for you. It will explain the basic tenets of the OpenStreetMap community and how they apply in practice.

This talk with survey the bright and dark history of companies and professional involvement in OpenStreetMap, lay out the challenges that we face now, and chart steps forward to figuring this out together. I want to reset the vision of the position of companies in OSM, starting by connecting back in time to when it was all more fluid in our community. Only later did some draw a sharp distinction between volunteer and professional activities in our project. The reality of the relationship of companies and professionals in OpenStreetMap from the very earliest days until today is ... complicated. There's incredible mutual benefit and purpose. There are super hard issues to address when large amounts of resources are mustered, among the constellation of many kinds of actors and motivations in OpenStreetMap. The reality is that OpenStreetMap is transformative, and that companies in OSM first come for the data, may fumble along the way, and stay for the shared mission to change how maps are made in the open.

The talk will focus on the Turkish law egulating the acquisition, collection, dissemination and trading of spatial data falling within the responsibility matrix of Turkish National Geographic Information System, effective since February 20, 2020. With the law, acquisition, collection, dissemination and trading of spatial data which is defined within the National Spatial Data Responsibility Matrix by third party individuals or legal entities are subject to prior application fees and approval of the Ministry of Environmental and Urban Affairs. The talk will reflect and report the developments in Turkey after the law, effects and implications drawn focusing on the national spatial sector, OSM, and the Turkish OSM community.

Map Kibera has been working for the past two years with some of Kenya’s county governments to create maps of their primary features and funded projects. After implementing a Participatory Budgeting process, these counties realized that without good maps it was difficult for people to not only allocate resources, but to work with citizens to identify needs and prioritize funds. Map Kibera has been assisting counties to map key features and projects in OSM by working with youth from the local communities. The maps not only serve to connect citizens to the budgeting process and hold county government accountable for the funded projects, but, they have also become central to county functions in all areas. This talk will share all about the process used and outcomes.

How I used OSM data to visualize gender disparity in street names for all of Brazil. The result shows how women are underrepresented in street names in the country, and raises questions on who is chosen to be commemorated in street names.

Want a postcard? Looking for somebody to send a postcard to? Me too! Let's discuss how people in OpenStreetMap come together, which pleasant and otherwise experiences we had meeting other mappers, and how to express gratitude and make people feel a bit closer to each other — with postcards.

We have seen an explosion of OSM mapping in the last few years around maps for development and humanitarian uses, particularly in Africa. During this time it has also become clear that sustaining this essential mapping work, and keeping maps up to date, was going to be a primary concern. Building a healthy mapping ecosystem around mapping for development will not necessarily be able to follow the same model as it has in more developed countries. In this talk, I will share the culmination of my research on sustainability with the World Bank’s Global Facility for Disaster Reduction and Recovery and their Open Cities Africa project, and some ways that we can best support mappers and grow a healthier global OSM ecosystem.

Do you get together with other mappers in your town? Would your group benefit from a bit more support? In this talk you will learn about the newly reformed Local Chapters & Communities Working group and our effort to support mapping groups all over the world.

In Cusco, Peru, during the last 2 years, GAL Center worked with students using OSM and associated tools, such as Kobo as educational tools, mainly for research into social problems that the students themselves identify in their locality. Projects such as “Sexist advertising mapping”, “Sexual health” and “Garbage mapping in Larapa” were the result of this work.

This year, MapImpact is one of the HOT Microgrants and we will work with high school students and YouthMappers Chapters that we help to create in universities. In this talk, I will tell you more about how we work MapImpact in GAL: our objectives, our methodology, our results and why we would like it to be replicated in other places.

OpenStreetMappers are a diverse group of people. This short segment will introduce you to another person that makes the project what it is.

The Philippines is to be considered one of the most-LGBT friendly countries in the World. In 2019, it was able to host the largest pride celebration in Asia. Amidst all this, crimes against LGBTQ+, discrimination, and bullying is still rampant in the country.

The Sexual Orientation and Gender Identity Expression (SOGIE) Bill is still continuously being delayed. It is intended to prevent various economic and public accommodation-related acts of discrimination against people based on their sexual orientation, gender identity or expression. Despite of being tolerated, the LGBT community is still far from being accepted by society.
Evidence of our community have been written on books, told in stories, presented in movies and yet the community has not left its mark in data. Spreadsheets, research, books have identified spaces where community activities happen but this are not shown on any map online. Our spaces are mere descriptions or addresses on tables and paragraphs.
This talk would be about how we would be more represented on OpenStreetMap so as to provide emphasis on being on the map.

The number of OSM contributors every year tends to increase. But not all are sustainable contributors. For example in Indonesia, there is a lot of OSM training and Mapathon but it is suspected that there are not many local contributors of all time. For this reason, extracting information from OSM accounts that have been registered since a few years ago that classified as a rare mapper. The method is by recording the top 500 accounts in Indonesia, identifying local accounts based on profiles and heatmaps, sending questionnaires, and summarizing them. The results can be used by the Indonesian OSM community to increase the sustainability of the contribution of local people in OSM.

Plenty of research about behavioural differences between men and women for years ago. According to a scientific article in 2013 by Lewis, on average women may have better verbal memory and social cognition, whereas men may have better motor and spatial skills. Moreover, spatial skill is really needed for mapping, especially as a mapper volunteer in OSM that everyone can make their own map. It also has been known that male mappers more dominate OSM mapping than female mappers. Nevertheless, in some mapper communities, the number of female mappers more than male mappers, for example in Humanitarian OpenStreetMap Team Indonesia. 19 from 30 mappers in HOT Indonesia are female, yet does it affect the performance and quality of mapping in OpenStreetMap?

In an ideal map, every point is reachable to another. However, in OSM data for instance, only 98.59% of Singapore’s nodes are reachable to each other by a path. In this talk, we identify OSM map problems by checking the connectivity of the road network using strongly connected component algorithms and introduce a creative visualisation to help map ops pinpoint the fix effortlessly. Using this approach, we have fixed thousands of map problems in SEA.

The collaboration between the Italian Alpine Club (CAI) and OpenStreetMap (OSM) officially began with the signing of an agreement between CAI and Wikimedia Italia, the Italian chapter of the OSM Foundation, in 2016.
The first activity was to define a standard to be used for CAI objects to be mapped using the wiki, and this started the mapping.
Three years after that signature much has been done with a surge in the last year also thanks to the funding of CAI through the project "CONTRACT FOR THE DATA IMPLEMENTATION SERVICE IN THE INFOMONT SYSTEM". This financed one person to carry out different activities:
- the data entry in OSM with the procedure used and the situation region by region
- the development of software released under a FOSS license able to obtain CAI data from OSM and carry out some conversion and reporting operations
- training activities in the different sections of the CAI
During the presentation will be made a history of the activities of the CAI with OSM, the results obtained so far and the various features of the software developed.

Trufi Association NGO offers an open-source journey planner app for formal and informal transport, based on public transport mapped in OpenStreetMap. In this extended talk, I would like to explain, how the participants can be customize the app to their own city, region, and country.

To assess the possible human and financial losses of earthquakes and to estimate the long-term earthquake risk that many people on Earth are exposed to, detailed knowledge of buildings is paramount. This encompasses not only the position, size, and type of buildings, but also the reconstruction value and the number of people inside the building at any time. Using OpenStreetMap data and further open data, we are implementing an open, global, dynamic, purely algorithmic, and reproducible exposure model for the probabilistic description of the aforementioned parameters for every building on Earth, growing and changing with every edit in OpenStreetMap.

Most field program managers have their go-to field preparation checklist - this often includes a data model, their preferred data collection tools, field survey timeline, to name a few. We are often cautioned about the importance of community entry, and it is right, you will not be able to just enter the community and start mapping as people will get curious, ask questions and possibly become suspicious or hesitant to accept your data collection activities. At HOT, we employe participatory mapping methods and encourage local people to map their communities. However, sometimes with even all the correct steps followed, your activities can be hindered due to factors outside of your control. In this session, we will explore one of HOT’s field mapping projects implemented in Kampala in collaboration with the Kampala Capital City Authority that aimed to map community-level flood risk in a local suburb along the Nakamiro Channel catchment area. Despite all the correct steps taken, community entry in a specific jurisdiction felt impossible and field mapping could not be carried out. In this session, our aim is to first discuss what went wrong and how our field team approached this situation and later invite participants/attendees to share similar challenges experienced in the field and how these situations were overcome or addressed.

OSM is more fun and useful with quicker access to fresh data. New web services, tools and file formats enable mappers to download and use edited data within minutes.

Walkability is the foundation for urban life that is sustainable, inclusive, healthy, and dignified. Pedestrians First is a new open-source suite of tools for using OSM data to measure indicators of urban walkability. During this talk, we will examine the nature of walkable and unwalkable cities, we will discuss the opportunities and limitations of using OSM to measure walkability, and we will consider possible avenues for extending Pedestrians First in the future.
