OpenStreetMap is the human-made map of the world. But how can one tiny human still make a difference in a project used by megacorps and crucial to millions of app and website users every day? How does OSM retain its individualism in a world that wants it to be consistent, orderly and predictable? Is it game over for the experimental, iconoclastic, independent map? Richard Fairhurst offers a challenging but upbeat look at the changing landscape for the OpenStreetMap mapper, user and developer.

2004: A crazy hobby project. One street mapped. One small mailing list. 2013: Edited by thousands every day. Beloved by hobbyists. Trialled by a few adventurous companies. 2022: The world's map. Worth billions. Used by everyone. What happened? Is there still a place for the individual in OSM, as mapper, user, or developer? How do you build with OSM when your competitors have free money on tap? Can OSM retain its iconoclasm and individualism when the Silicon Valley behemoths are involved? Richard Fairhurst is still as idealistic as in 2004 (but maybe a little calmer) and thinks that corporate OSM and independent OSM can co-exist, and better still, benefit from each other. In a wide-ranging, rollicking and occasionally factually accurate talk, he'll look at the OpenStreetMap economy in 2022 and how individuals can still make a difference. Expect: the secretive Kindred of the Kibbo Kift, situationists, books about pubs, bouncing phones.

First there were DJs and VJs. Enter the MJ (map jockey). Carto-OSC leverages open source libraries, data, and protocols to activate performance spaces – theaters, galleries, nightclubs – with projected, real time cartography. The Open Sound Control (OSC) protocol couples with a touch surface to control layer coloring and patterning, zoom/pitch/bearing effects, label typography, transits along road networks, and a variety of transitions purloined from cinema and visual music. Written in modern JavaScript, Carto-OSC would be unthinkable without a foundation of Open Stage Control, MapLibre, chroma.js, and OpenStreetMap data. This presentation describes its architecture, the impulses behind its creation, and includes documentation of its use in performance.

MapRoulette was first announced at State of the Map US in 2012 as a tool to solve the many errors introduced by the import of TIGER road data in the United States. Since then, MapRoulette has been used for map improvements and guided data imports around the world. In this talk, MapRoulette creator Martijn van Exel will look at some of the achievements, lessons learned, and the evolution from a single purpose tool to a micro-tasking platform.

[MapRoulette](https://maproulette.org), the open source web-based micro-tasking platform for OSM, was first announced at State of the Map US in 2012 as a tool to solve the many errors introduced by the [import of TIGER road data](https://wiki.openstreetmap.org/wiki/TIGER) in the United States. After a successful and quick cleanup of over 60.000 common problems found in the TIGER data, it was clear that the idea of a micro-tasking tool was worth developing further. Over the years, MapRoulette gained a lot of functionality while staying true to its original goal: supplying the OSM communuty with quick, easy to solve tasks that help fix or improve the map. Nowadays, anyone can create tasks [using Overpass](https://learn.maproulette.org/documentation/using-overpass-to-create-challenges/#content) or GeoJSON, there are [new task types](https://learn.maproulette.org/documentation/creating-cooperative-challenges/#content) that make fixing problems in OSM even easier, and there is support for working in teams. In this talk, MapRoulette creator Martijn van Exel will look at some of the accomplishments and lessons learned in 10 years of MapRoulette, and highlight some interesting uses of MapRoulette over the years. If time allows, he will also show some of the newer functionality that may not be as well known even to experienced users.

Having made your first edits with JOSM, there are a couple of tips and tricks to learn to make your daily mapping life in this JOSM easier. JOSM, considered an advanced mappers tool, is an easy-to-use OSM software that makes mapping in OSM easier and more interesting using plugins and various mapping tools.

This workshop aims to introduce those with JOSM for beginners skills to advanced editing techniques in JOSM. We will provide help with your first steps to plugins and mapping tools on JOSM,, introduce tips and tricks working with complex shapes, background imageries settings, to do list plugin among others. If you’re a newbie to OSM, I encourage you to go through ID for beginners and advanced ID tutorials first before this workshop. This will give you the chance to compare ID and JOSM during the workshop and get to appreciate JOSM and the techniques you will learn from it. All workshop attendees are required to download the latest version of JOSM prior to joining the workshop. See https://josm.openstreetmap.de/wiki/Download for an installation and troubleshooting guide. In addition, please install these plugins: buildings_tools, todo, utilsplugin2. See https://josm.openstreetmap.de/wiki/Help/Preferences/Plugins for how to add plugins. Don’t forget a mouse.

By 2025, HOT aims that communities in 94 countries vulnerable to disaster or experiencing multidimensional poverty are equipped and able to map the locations where they live and work. We believe that accessible mobile mapping tools are key to this effort. Since I started working for HOT in January 2022, I have done informal interviews, observations, focus groups and experiments with more than 100 regional users, primarily in East Africa, looking at the accessibility of current OSM mobile editing tools. Sharing this research with the wider community will help everyone build technology that fits the needs on the ground.

For 3 months, with the support of OpenMap Development Tanzania (OMDTZ) and the State University of Zanzibar (SUZA) Youth Mappers, I did a variety of informal interviews, observations, focus groups, and experiments with individuals and local OpenMapping organizations, primarily in East Africa. My research included professional data collection campaigns, as well as entry-level community members whose first encounter of OSM was during one of my workshops. While the majority of my research focused on 5 main Open Source applications that are already in widespread use (StreetComplete, OsmAnd, Organic Maps, Vespucci & ODK Collect), many of the insights gained from this research, including data about hardware availability and current phone use, are applicable to anyone building mapping tools, especially those that will be used in low-resource environments. The HOT _tech team aims to do more than just talk. Analysis of the research will be followed by specific suggestions for those doing mobile OSM mapping, especially at the entry-level, as well as technical proposals for tooling improvement. We will be working with the existing OSM ecosystem to design and implement these proposals in a way that is inclusive and sustainable. Feedback is most welcome.

Presentation of the work we've done to adapt the OSM Carto style to vector tiles. We will take you through the making-of the cartography, step by step, scale by scale. Available on MapTiler Cloud (https://cloud.maptiler.com/maps/openstreetmap/), the style will be integrated into the next version of the OpenMapTiles project. We will also show you how to use this style in QGIS and how to display it on 3D maps with MapLibre.

The MapOSMatic web frontend allows to create printable maps from OSM data interactively. This is not the only way to use its rendering backend, it is also possible to directly use its ocitysmap Python library to render maps from your own Python code and a local stylesheet and database setup, or to use the REST-like API of the web frontend to send automated render requests to a MapOSMatic web instance from almost any programming language without any local setup effort. The presentation will give a short overview of both API variants, showing the different options to interact with the MapOSMatic render infrastructure programmatically. As example applications an alternative neighbourhood

Usability testing can be done without hordes of users to observe, in fact just three people is likely to give very useful hints. And it is almost certainly more useful than expected, and your software is likely not as good as you expect. This is based on my experience with using user testing while developing StreetComplete.

Join the Local Chapters Congress to learn about what other chapters are doing. Even if you are not on a Chapter but are a local organizer, feel free to join! We will focus on: - how to turn actions that work locally in projects that can be ran globally - how local groups can best help each other

Join the Local Chapters Congress to learn about what other chapters are doing. Even if you are not on a Chapter but are a local organizer, feel free to join! This session is organized by the Local Chapters and Communities Working Group, which is is tasked with finding and implementing ways for the Foundation to support the growth of local communities and potentially encourage established communities to further organise themselves and eventually formally affiliate with the Foundation as one of its Local Chapters. Aside from that, the LCCWG facilitates a global exchange of ideas and support among Local Chapters and communities and review and suggest improvements to the Local Chapters affiliation scheme. Local Chapters are not-for-profit legal entities to be established within different territories around the world which can act as official local representatives of the Foundation when dealing with local government, business and media. OSMF is an organisation is incorporated in Great Britain. It wants to support the OpenStreetMap project (and other free mapping projects, where applicable) in the whole world. But it can't be everywhere and reach everybody, especially people speaking languages other than English. Local chapters can extend the reach of OSMF, foster local communities, help with legal and financial matters in their respective countries and generally promote OSM in their local areas. Some of these goals (such as handling financial matters or providing a point of contact for government or media) can also be handled by totally independent organisations supporting OSM but not associated with OSMF in any way. But working together helps OSM and makes it clear that we are all part of the same community.

OpenStreetMap consists of tagged nodes, ways and relations. Many use cases of geographic data, however, need a tabular dataset of points, lines and polygons. Processing OSM into derivative datasets is a crucial task that can benefit from new tools and formats. This talk will cover several topics around this theme, including: * Existing approaches such as the Export Tool * Why FlatGeobuf is a suitable forwards-thinking format * Computational challenges for processing global-scale relations * A new open-source program, Protoshapes, to generate admin polygons in FlatGeobuf format * Efficient approaches for global datasets such as coastlines, oceans, and road connectivity * Frequently updating datasets using the open-source OSM Express database

Understanding the limitations of data is hard. Some tags are missing, and some tend to be present only when others are. Is the missing tag saying something, is it just unknown? When tags take yes/no values, is a missing tag an implicit "no", maybe the tag "does not apply", or something else…? This talk doesn’t have answers. It’s the journey we took through an investigation of road data in London. What we found, what we think about what we found, and ideas of things to compute and visualise, before performing an analysis - or to decide if the data is just not suitable for this analysis.

We would like to share our feedback on facilitating OSM participatory mapping workshops for climate change adaptation projects with OSM local communities Since 2015, CartONG has been expanding its work into the domain of participatory mapping, first by partnering with the international Missing Maps project, and then by working to develop a wider set of tools and methodologies. Over the last 12 months, we had the opportunity to support two climate change adaptation projects, one in Tajikistan for the German Corporation for International Cooperation (GIZ) and the other in Madagascar in the Morombe region for Secours Islamique France.

For these projects, we used geographic data and open source technologies, especially OpenStreetMap, and based on a participatory approach by mobilizing and fully involving local communities. We also worked to promote cooperation between the different actors in the region. At this conference, we want to share our field experience and approaches to increase the production and availability of geographic data in the concerned regions and initiate new groups of local contributors to enhance and maintain the OpenStreetMap database.

Through open mapping, we hope to inspire local youths and leaders to use technology to improve and create sustainable local governance system. We engaged 44 youths from 3 municipalities to participate in open mapping in first phase. In second phase, we gathered 10 IT officials from province 2 and highlighted OSM to connect geospatial elements for better local-level administration. Here, we will discuss our methodological framework, challenges, how we gained support from local units to coordinate with community youth, and impacts we successfully created. This talk will be relevant to those interested in laying a strong foundation not only for better governance but also for engaging youths.

The success of local governments in meeting development targets is crucial for the goals of federalism in Nepal. The local governments have a colossal opportunity to set the course of development based on people’s aspirations, as citizens have increased power and responsibility to choose and act on their agenda in the federal system. However, these governments face daunting challenges in human, capital, and other resource constraints. Innovative citizen-centric approaches are necessary to navigate these challenges to achieve the development goals. It is also imperative to note that properly achieving the development goals and measuring their progress is contingent on decision making and planning, driven by data. Geospatial data is valuable to the local economy and community in various aspects. The openness of the information, or more specifically the freedom to access and use such open data, is crucial to achieving such multiplier effects of taxpayer-funded data generation processes. So hereby, our interest lies in training and encouraging local youths and leaders to leverage technology for good governance through open mapping in coordination with local administrative units. Our initiative looks beyond the myopic vision of training a handful of youth on digital mapping to create a limited number of outputs, i.e. maps. We implemented a mechanism in which we created a batch of OpenStreetMap (OSM) leaders, who in their regions, can inspire and enable such processes beyond the life of any particular project. As such, we wanted to set in motion a process that can beget far-reaching, longer-term benefits in the form of active citizenry (on the youths’ part) and data-driven development (on the local governments’ part). This will be in addition to the immediate, short-term outputs such as up-to-date maps and enhanced mapping skills of the mappers. In the first phase, KLL trained 44 citizens from 3 local bodies in the use of OSM and mapping in coordination with the municipality. The trained youths were also involved field data collection. Simultaneously, we started remotely mapping the municipality. Based on the need, we collected field data to complete the map. On mutual interests and availability of resources, the mapping of the local governments included points of interest like: Roads, Settlements, Educational institutions, Health facilities, Government offices, Banking institutions and others as agreed upon by the municipalities. Using the data hence collected, we created softcopies and hard copies of ward (smaller administrative unit of government in Nepal) level and municipality level maps and handed them over to the municipalities for their use. In the second phase, to ensure better understanding of OSM within the local governments, we trained 10 IT officers from Province 2 on OpenStreetMap, its uses and applications in local governance. We also led a focused group discussion on how open mapping can be utilised by municipalities, what features need to be mapped for the integration of OSM in local governance and challenges they foresee in this process. Hence, we will be discussing our methodological framework and challenges in involving local youths and leaders in open mapping and in contributing to develop more promising local level governance. We will also share how we gained needed support from the local units to coordinate with the youth of the community and the impacts we successfully created. This talk will be relevant to those interested in laying a strong foundation not only for good governance with the core idea of open mapping and its application at its center but also for involving local youth in the process.

The OSM data model with its nodes, ways, and relations has done an amazing job for us over the years. It has seen very little changes since relations were introduced 15 years ago. But there are some real problems with the data model. With the experience of those 15 years behind us, its time to tackle some improvements. This talk will outline the problems with the data model, show ideas for improvements, and discuss possible ways that can move us forward step by step.

The OSM data model is quite different from the "Simple Feature" data model used by most "geo" software. It has some great features, like the open tagging model, which has proven to be a great enabler for all sorts of innovations. But the data model also has its problems. Most often named are the missing area data type and the cumbersome geometry building needed for ways and relations based on their member nodes. This makes use of the OSM data more difficult, more expensive, and slower than it needs to be. There has been some discussions on these topics over the years, mostly after my talk in 2018 at the SotM in Milano, but work on this has stalled. Recently the OSMF Engineering Working Group has taken up this topic and payed me to do a study on the problems with the data model and possible ways forward. This talk will present the findings and should jumpstart the discussions around this in the OSM community.

OSM has an unrestricted tagging model. Mappers can invent and use any tags. While this is part of OSM's success story, it has lead to a database where the globe is described in ever greater detail. In this talk we want to explore how users of OSM data handle a tagging model with so few constraints. Richard, the owner of cycle.travel, and Sarah, maintainer of Nominatim, team up to share their experiences of a decade of working with, and occasionally fighting against, OSM's ever evolving tagging schema.

The OSM tagging model has significantly evolved since the first streets of London were put into the database. Not only are more and more different objects in the database, we also capture more of their properties and want to model ever finer nuances. This clashes with our goal to have one database for the entire planet. The closer we look the more differences between different regions there are. And to capture those the tagging has to become even more complex. Using the examples of the cycle tour planning site cycle.travel and the search engine Nominatim, we explore the evolution of OSM tagging from a data user's point of view. Looking at questions like * where do data users get their information about tagging * what kind of tagging can be practically used in software * how to handle local defaults and assumptions * how should OSM ideally document its tagging

Christopher Beddow takes us on a journey of how to map a small town using a variety of tools. The goal was to test and prove how much OpenStreetMap can be enriched using RapiD buildings and roads, and Mapillary map features, traffic signs, and imagery. He evaluates a small town in the western United States that is far from any mapping community and has very little data, and demonstrates how a vivid dataset can be added to OSM. In addition, he compares this to a small town in Switzerland, demonstrating how new details can still be added to a place that is heavily mapped by a strong local community.

Mapping is a time consuming task, and challenging for an individual to do without a community or a team. However, many tools exist to enhance the capabilities of any lone map contributor, and also multiply the mapping power of a team. Christopher Beddow takes us on a journey of how to map a small town using a variety of tools. The goal was to test and prove how much OpenStreetMap can be enriched using RapiD buildings and roads, and Mapillary map features, traffic signs, and imagery. He evaluates a small town in the western United States that is far from any mapping community and has very little data, and demonstrates how a vivid dataset can be added to OSM. In addition, he compares this to a small town in Switzerland, demonstrating how new details can still be added to a place that is heavily mapped by a strong local community. Leaving this talk, you will understand how to use RapiD, Mapillary, and your own creativity to adapt your own locality into a comprehensive part of OpenStreetMap.

Mapping is time-consuming and requires a high workforce when it comes to keeping maps up-to-date. Mapillary brings a different approach to geospatial data collection with street-level imagery. This approach allows communities to collect geospatial data faster and cheaper. But can Mapillary-generated data be useful for enriching OpenStreetMap? In this study, Mapillary-extracted map data will be examined against ground truth to assess data quality on contributing to OpenStreetMap.

In this case study the positional accuracy and completeness are assessed by benchmarking Mapillary-generated data against ground truth for street light provided by Ordu Metropolitan Municipality in the borough of Altinordu, which covers an area of 9 km2. A total number of 323 street lights were recorded in the authoritative dataset. Completeness and positional accuracies are evaluated for each street light for different camera setups. In order to compare the impact of camera type on positional accuracy, street-level imagery was collected with three different cameras: iPhone 11, GoPro Hero 7 Black and GoPro Max. Collected street-level imagery was uploaded to Mapillary by using the Desktop Uploader. Imagery which are captured from different cameras is isolated during the upload to compare map data accuracy, completeness and correctness comparison based on camera type. In this experiment, we validate the effectiveness of Mapillary extracted map data by focusing on streetlights by evaluation results based on completeness and positional accuracy key performance indicators. The best result of completeness is achieved with GoPro Hero 7 Black with 87.57% in the working area and it is followed by GoPro MAX with 77.30% for Mapillary extracted street light data . Lastly, the completeness of iPhone 11 acquired data is 71.89%. In terms of positional accuracy, our experiment shows GoPro MAX captured street-level imagery can be extracted with 2.02 m of positional error and it is followed by GoPro Hero 7 Black with 2.17 m of positional error. The average positional error of street light which is extracted from iPhone 11 captured street-level imagery is 2.21 m. This positional error is close to the precision of a single frequency GPS receiver. This experimental study shows that positioning accuracy is highly related to the GPS accuracy of the capture device, and in general, a large part of the final positional error can be attributed to this. Mapillary's 3D reconstruction is able to mitigate some of these effects. Additionally, capturing with a large field of view has a positive effect on accuracy. In this study we also validate that positional accuracy depends on various factors of the capture process; precision of GPS receiver and additionally positioning hardware, resolution and quality of the images, image capture frequency of the camera, imagery density in the working area and type of photo such as flat or 360. The overall positional accuracies are under 5m which can be a promising solution for enriching street lights data on OpenStreetMap and collecting streetlights inventory for the municipalities and governmental bodies if this data will not be used for surveying purposes or reference data, however Mapillary-generated data can be useful and time effective as complementary data with low cost collection expenses.

Digital maps are ubiquitous tools in our everyday life. In the early 90s, the idea of browsing the world digitally and visiting any place was groundbreaking. The first solution to this problem is known as "TerraVision", which was breathtaking. Today, the idea of exploring your surroundings using digital maps has become normal. But how do these maps work? In this talk, I want to provide an overview of the foundations of digital mapping solutions. Differences between maps which use vector data and rasterized satellite imaginary will be outlined. Furthermore, a new and open-source map renderer called maplibre-rs will be presented, which is created using Rust and WebGPU.

Last year I had a lot of spare time and decided to kick-start a project which combines different areas of interest: Rust, 3D rendering, Geo data This project was adopted recently by the [MapLibre](https://maplibre.org/) project and is now known as [maplibre-rs](https://github.com/maplibre/maplibre-rs). The maplibre-rs library is a proof of concept which showed me the complexity of mapping solutions. It takes a lot of steps until edits from OpenStreetMap contributors are finally rendered in consumer applications. With this task I want to take listeners on a journey from drawing changes in the OpenStreetMap editor all the way until vectors are uploaded to from memory to GPUs. Like outlined in the abstract, I want to cover multiple topics: * Foundations of digital maps (How to determine which data should be loaded? What are vector and raster tiles?) * Show the technology stack which allows us to design and develop a cross-platform map renderer (Web, Mobile, Desktop)

Coverage of `maxspeed` data in OpenStreetMap is very sketchy (about 12%). This situation is unlikely to change because the limits are often not signed explicitly. So, data consumers such as router software need to compensate huge holes in the data with more or less rough estimates based on other data. This talk shall explore a method how to infer default speed limits for different vehicle and road types more precisely for each country.

The geospatial world is moving to cloud-first and cloud-native approaches. Movements like STAC and COG have transformed how people use raster data in the last couple of years. OpenStreetMap has much to gain from thinking about different cloud infrastructure architectures. This talk will discuss what it takes to run the OpenStreetMap ecosystem in the cloud and present the history and work on a project called [OSM Seed](https://github.com/developmentseed/osm-seed/). We learned so much while building OSM Seed and think it can be a blueprint for running OpenStreetMap on cloud infrastructure.

The OpenStreetMap ecosystem contains many open source software projects beyond the Rails application. This includes tools that are used by mappers on a daily basis, like, Overpass, Tasking Manager, iD, JOSM, tile servers, data processing applications, Nominatim and so on. It’s a complex ecosystem of growing tools. These are maintained by different individuals and organisations. OSM Seed started in 2018 after several attempts to containerise OSM software for easy installation. [I talked about this vision](https://2015.stateofthemap.us/openstreetmap-software-for-more-than-openstreetmap) in 2015 at State of the Map US. Since then, OSM Seed has grown to be a mature and heavily tested software project that now powers projects like OpenHistoricalMap and data projects at Humanitarian OpenStreetMap Team. We learned so much while building OSM Seed and think it can be a blueprint for running OpenStreetMap on cloud infrastructure. OSM Seed uses cloud agnostic approaches through Kubernetes to bring together projects that make up what OSM is today. These projects continue to get updates and are maintained how they always have been. OSM Seed provides an interface to bring the ecosystem a little closer through better infrastructure orchestration. In this talk, I’d like to discuss a brief history of OSM Seed, some of our lessons trying to move OSM software to the cloud, and open a conversation on what could be useful for OSM going forward.

RapiD is the OpenStreetMap editor that enables users to access a wide variety of shared open data and a machine learning generated predictions that can bring new detail to the map. In 2022, the team at Meta upgraded RapiD to enable users to validate and verify Mapillary detections from images and add data to OpenStreetMap. Join us in an instructional workshop and mapathon where we will learn how Youthmappers in Sierra Leone are using Mapillaryto map the power grid across the country, and how the same workflow can be applied to map electricity availability and lighting around the world, anywhere users capture Mapillary and utilize RapiD to enrich OpenStreetMap.

Goals: - Introduce the project for utility pole/power line mapping in Sierra Leone - demo how to capture Mapillary imagery - walkthrough on how to use RapiD for adding utility poles and street lamps - guided mapathon with focus on Sierra Leone and option to replicate anywhere the participant wants, such as their hometown Logistics: - projector screen - classroom environment good for lecture + laptop work - bring your own laptop + mobile phone - access to wifi needed (we can try to hotspot via my phone) - we will try to provide a few laptops, but if the venue can provide any it will be helpful for using OSM iD/RapiD

Open data is a trend in Taiwan, and some community members of OpenStreetMap or Wikidata are importing or merging information they obtain from government sources into the corresponding OpenStreetMap and Wikidata Database. The village dataset is available by sharp file and detains metadata with reference numbers, and the river dataset covered big rivers in Taiwan. In this talk, I will talk about the process of importing data, maintaining data, and linking each data not only with the government source but also to OpenStreetMap and Wikidata.

I will not only talk about dealing with the village and river datasets but also with other import project in Taiwan, like Taichung address dataset import, schools, kindergarten, etc. And I will also have a short introduction of Taiwan community activities, both OpenStreetMap and Wikidata. Recently OpenStreetMap Taiwan got funded by Wikimedia Foundation to improve Taiwan mapping data and also Wikimedia related projects like Wikidata, Wikipedia, Wikivoyage, Wiki Commons, etc.

Across OpenStreetMap there are ways to get involved from working groups to events to boards. How can we increase and deepen participation across the world? What is the current state of engagement/governance in OSM? What do we need to do to improve? What are some of the lessons from other open organizations?

Proposed Outcomes -Inspire people to join play a bigger role in OSM - working groups, boards, governance -Engage a larger discussion about diversity, equity, and inclusion with a shared leadership approach -Infuse the OSM network with insights from other ‘open projects’ on their insights Notes We want to make this as accessible and inclusive as possible. Thus - calling it ‘governance’ won’t build participation. For years, there has been sessions on ‘working groups’ and ‘meet the board’ or meet ‘weeklyosm’. These are valuable, but we need to go wider and deeper. How can we learn about our shared network and build momentum in participation /engagement and leadership?

Boundary conflation is a sensitive and difficult problem to solve. When administrative boundary data is available from authoritative sources for OSM, it is imperative that we have the ability to analyze boundaries for import and deduce if conflation with OSM ways can be done hopefully in a semi-automatic fashion. "Admin Boundary Conflation" is a special-purpose tool made for the purpose and this talk will introduce the workings of the tool to the audience along with the various output statistics available during the process. Currently, the tool is utilized for reporting geometric area differences of 0.01% in the 99th percentile of 5000 municipalities in Serbia within 20 minutes.

Since twelve years OSM has become a database that is heavily used around the world by various actors for various goals. We can mention navigation through mobile GIS application, map production, Geoportal deployment and others. In Togo, OpenStreetMap by its data and its tools were increasingly used in the framework of the national social and economic facilities Census project. This presentation will show how OSM was useful in this country-scale mapping project.

As part of the implementation of Togo’s Government roadmap 2025, it is planned to implement, among other initiatives, the project to map the social and economic infrastructure of municipalities and districts of the country. The final goal of this mapping project is to develop tools for analysis, management and optimisation of decision-making based on geospatial technologies and data for the central administration, technical services of the State and local authorities. OSM tools have been very helpful in several steps of the project. OSM tools have been very useful in the implementation of the project. Our presentation will highlight the steps and how OSM and open geospatial tools were used for the success of this national mapping project of Togo.

This talk will cover the growing New York City OpenStreetMap community and our efforts at coordinating mapping our cities’ quirks into the OSM data model. New York City (and much of America) has sidewalks that end abruptly, intersections without proper pedestrian control, uncontrolled slip lanes, bike paths that lead into stairways, crossings without curb cuts. Mapping these features helps NYC pedestrians analyze conditions, report and advocate for changes.

he New York City community is interested in keeping track of pedestrian features throughout the five boroughs. Both to improve routing and to keep track of dangerous or poorly designed infrastructure. While NYC is required by law to create accessible conditions, our sidewalk mapping today helps find areas that do not yet meet those standards. OpenStreetMap contains the most up to date resources for the city’s bike lane network, including planned projects. Discussions helped standardize when to draw bike lanes separated from the road lane (when there is a barrier) and coordinate responses to new construction (the race to survey the new Brooklyn Bridge bike lane.) While the city may consider a certain segment protected, OpenStreetMap’s “on the ground rule” brings our maps closer to reality. In 2021 the community came together to focus on completing sidewalks in Flushing, Queens. In 2021 and 2022 the community mapped bicycle racks using fieldpapers. These efforts show how to organize support to improve a single area, and bring in new mappers with an activity focused on a single goal. Completed areas can then drive analysis. I will share examples of areas that have been mapped and where they brush up against the guidelines for bike and pedestrian mapping. I will also share analysis driven by this mapping. Finally there will be anecdotes having reported issues to the city and keeping track of progress with OpenStreetMap.

Every day hundreds of people sign up for OpenStreetMap. We have several active OpenStreetMap communities, communities that are struggling to sustain themselves and at the same time, there are countries with no existing OpenStreetMap communities despite having contributors from those countries. This idea of a community playbook is to act as a guide for persons interested in starting up an OSM community and sustaining OSM communities with lessons drawn from existing communities. The community playbook is based on 4 themes; Identifying local community issues, attracting and engaging students, Connecting contributors motivation to mapping and Training

OpenStreetMap has proven to be a really interesting and valuable classroom instrument. Making students work with OSM allows them to develop the soft skills entailed in cooperation, to interact with something bigger than their class or school and to give their contribution for the sake of the collectivity. In this particular experienced, we worked on the local area of Bari with a class with 17 female students of a "Liceo Economico-Sociale", a school not particularly engaged in the STEM field. Thus, we also wanted to help them get more confident with the STEM field, which desperately need more diversity. Furthermore, focus has been on accessibility.

During the talk, we will explain what we did during the project and the outcomes. The activities involved: * an introduction to OpenStreetMap, ID editor, licenses, but also Wikimedia projects * a phase of physical mapping, in which we visited the city centre of Bari using field papers and StreetComplete to map shops/restaurants/cafes and their accessibility status, accessibility ramps and other useful information to add both on OpenStreetMap and on Wikivoyage * the editing of OpenStreetMap and Wikivoyage to add the information gathered. In addition to what explained in the abstract, we would like to underline how the experience benefited equally the territory, thanks to the improved geographical information and also tourism information, the students, because of the worthwhile experience they have gained and the rediscovery of the STEM field, and the community, not only because of the new information added but also due to the increment (even if little) of diversity in contributors. As explained, we did not contribute only to OpenStreetMap, but also to Wikivoyage, the official, non-commercial and freely-licensed (CC-BY-SA) sister site of Wikipedia for tourism guides, and to Wikimedia Commons, the free multimedia database of Wikimedia projects. The two of us, Ferdinando Traversa and Rosa Colacicco, are respectively the regional coordinator for Apulia and the OpenStreetMap coordinator for Apulia of Wikimedia Italy/OpenStreetMap Italy, so the project was endorsed and sponsored by the organisation. This project is consequently also an example of synergy between OpenStreetMap and Wikimedia projects, strenghtened by the fact that in Italy chapters for WMF and OSMF coincide. Rosa Colacicco is also the president of the YouthMappers@UniBA, the local group of YouthMappers which collaborates with the department of Geology of the University of Bari. In conclusion, we would like to present this experience as a case study in order to enable others to try a similar pathway.

Every day millions of users experience delightful features on Bing Maps. Each user, regardless of their technical background, possesses a wealth of local knowledge that can help improve map data which for many country regions comes from OpenStreetMap. The common OSM editorial tools iD & JOSM are far too advanced for our users. Hence, we embarked on a mission to build a very simple tool - MapBuilder - that can guide users to volunteer their local knowledge to update map data via a set of guided screens. This talk will focus on the following: - First features - Building community engagement - Identifying data gaps - Potential risks and mitigations

OpenStreetMap is a huge repository of geographic information – but how accessible is it? This panel aims at enlighting existing educational activities and platforms around OpenStreetMap topics, including editing, data usage and community governance, with the goal of exploring how new users and data consumers can approach OpenStreetMap in an easier way, and eventually widespread its adoption. During the panel we will discuss and share educational practices, experiences and tools and challenges.

During the panel, we will discuss existing educational activities and platforms around OpenStreetMap topics, including editing, data usage and community governance. When first approaching OpenStreetMap, learning tools and activities may prove to be highly beneficial for new volunteers in several aspects as well as for expert mappers to improve their knowledge. Education around editing may lead to higher quality of data both during collaborative events or, in general, over all the mapper’s lifetime. Mappers may have knowledge on OSM editing and complete lack of understanding on how the data can be used for software or cartographic applications. On the other hand, many data consumers may not know editing practices and how the tagging schema is refined and discussed in the OSM community. Understanding how the OSM community is interacting and governing the project, including exposure to the guidelines related to good editing practices, organised editing, imports and licensing, may have companies and professionals better understand how to behave in this environment. The goal of this discussion is to enlist and explore all the tools and activities that organizations and communities are developing around education on OSM, with particular focus on the audience covered by those as well as the languages this material is offered through.

The last 10 years were quite turbulent for the iD editor: After the initial idea from Richard Fairhurst was quickly picked up by a developer team at Mapbox, the editor became OSM’s default map editor almost exactly 9 years ago today. Since then, different Maintainers have managed the project, constantly enhancing its functionality and data models like iD’s built in tagging presets. This talk will present a condensed overview of the evolution of the iD editor since 2012 and, more importantly, showcase what still lies ahead of it: Small and large improvements to the user interface, performance, data validation, customization, integration of external services and more.

Almost exactly 9 years ago, the iD editor became OSM's default editor. But its core idea was first presented even a year before that. Looking back at the past 10 years history shows that the project has undergone quite a few different phases: The initial sparks and the coining of the name by Richard Fairhurst were followed up shortly by a rapid development phase by a team of Mapbox engineers resulting in iD being ready to stand in as OSM’s default map editor. Since then, different Maintainers have managed the project, constantly enhancing its functionality and data models like iD’s built in tagging presets.. In the last couple of years, the iD editor has also seen some usage outside of the main OSM website, for example in the form of Forks like the RapiD editor, advancing the applicability in their own specialized use cases and scenarios. This talk will present a condensed overview of the development of the iD editor since 2012 and, more importantly, showcases what still lies ahead of it: Small and large improvements to the user interface, performance, data validation, customization, integration of external services and more. All with the goal to make iD fit for next 10 years and more to come.

OpenStreetMap is a collector's dream. While there is a finite set of stamps or coins, there are millions of shops and beauty salons, and new ones are opened every day. Yay, collect them all for the map! (And make the map better in the process, of course.) Alas, this task was made tedious, virtually impossible by our current tools. Not as much for adding — but for updating the data we've already collected, and finding what's missing. I've talked many times of this problem, and this year I think I've fixed it. This year changes everything for how POI are handled in OpenStreetMap.

Last year I presented the idea of making cartography apps without a map for the central UI element. And added a couple drawings of a better editor for POI. Well, it is finally out there, and hundreds of mappers have already surveyed... a lot. So one part of this talk is a typical OSM editor talk: I'll walk you through the design decisions, show some statistics, and elaborate on how writing a new OSM editor is akin to writing a new browser these days: an enormous task, but with a lot of open source code at hand. But what is different, is that this editor is not a toy and not a general-purpose tool. It is very focused (well, on three things at once, but still). Meaning, you don't play with the map in it, and don't get lost in menus. You survey. Lots and lots and lots of shops and amenities are going to get added or confirmed. This editor does not just "allow" anything. It changes the landscape of OpenStreetMap. Before it shops were an afterthought — now people would seriously consider using OSM for searching. Here's where my experience in working with commercial places data comes in handy. Let's see what can we get out of this, and why "fun" is still as important in OSM mapping as always.

Our digital champions project in Tanzania has transformed the lives of 353 women who had never used a smartphone before into confident advocates of mapping in their extremely marginalised communities. They have delivered training to over 9000 women in these villages and reported over 470 cases of gender based violence in their villages to the police and social services who have then used the maps to find and protect these women. Giving local women and youth the digital tools to protect their sisters in their communities is an extremely cost effective, long term solution to build up our mapping community and make it more inclusive, and share lessons learnt

This workshop is aimed at everyone interested in using OpenStreetMap (OSM) to support sustainable transport planning, in professional or advocacy contexts. The focus will be on getting started, identifying, visualizing, and analyzing key tags and identifying gaps in walking, cycling, and wheeling networks. Participants will place OSM data in the context of other data sources to identify its unique advantages. The workshop will be practical and get users started with key ‘tools of the trade’ in the areas: R (used for live demo), Python, A/B Street, and osm2streets. By the end of the workshop, you will know how to add value to OSM data to support sustainable transport planning.

OSM data has been used in various public-facing transport-related contexts, such as routing services and navigation. However, the potential of OSM data in transport planning has yet to be fully realized. This workshop will provide insight into how OSM data, when combined with new and open source ‘tools of the trade’, can support more evidence-based and sustainable transport planning activities. OSM can also support citizen-led bottom-up approaches to understanding, prioritizing, and designing active travel infrastructure. This workshop, developed as part of the OpenInfra project at the University of Leeds, aims to address this gap and encourage OSM users to help release the full potential of OSM data for decision-making in the transport sector and beyond. Based on the ‘learning by doing’ ethos the bulk of the workshop will be practical, enabling participants to see how OSM data can be used to support better walking, cycling, and wheeling infrastructure and policies. Participants will be introduced to methods for getting started with OSM for transport planning, focusing on practical steps that can answer the following questions with live demo and practical in R (we will also discuss how to achieve the results in Python, A/B Street, and osm2streets): - What gaps in transport evidence can OSM data fill in different countries? - Which elements and tags are most important for transport planning (and how to get the data in reproducible data science environments)? - How to filter based on different tags and their values? - How to use OSM datasets to visualize transport systems in static and interactive maps? - How to add value to OSM data and communicate results using R, Python and A/B Street, and osm2streets? Besides practical examples, participants will be encouraged to think critically about the advantages and disadvantages of OSM data in sustainable transport planning with a particular focus on accessibility. By the end of the workshop, you will be able to apply the methods introduced in the workshop to your own unique contexts, potentially going beyond transport planning. Participants are not expected to be familiar with Python, R, A/B Street, osm2streets or active travel planning but experience with programming and an interest in active travel (walking, cycling, wheeling) will be advantageous. Before the workshop, everyone will be sent out installation instructions to complete before the start of the workshop.

The Amazon Forest, its traditional peoples, and riverside communities represent an immense challenge for official cartography, due to scale and extension factors. This presentation aims to show the experiences of the Unificar Ações e Informações Geoespaciais (UAIGeo) chapter of the Brazilian YouthMappers in mapping riverside communities in the Amazon rainforest region, focusing on the city of Tefé and its islands. Due to its female leadership role and the goals of empowering young women in geospatial and technical skills, the presentation emphasizes the importance of engaging and encouraging female students to link mapping and female empowerment.

In Brazil, it is still an immense challenge to produce official cartography on the regional and local scale due to the extension of the territory, the number of municipalities (5,568 plus the Federal District), and the expensive cost of producing the mapping. Such factors are more significant in the Northern Region of the Country, where an important part of the Brazilian Amazon Forest and many traditional peoples and riverside communities are located. Many of the riverside communities do not have records in documents about their ancestral knowledge, cultures, territories, etc. Their knowledge and stories are transmitted orally and, despite the importance of this legitimate source of data, an important amount of information can be lost over time [1] The distances between riverside communities, in addition to the small geographic space the built infrastructure occupies, make them invisible in many official mapping. The riverside buildings have about 70 m² and cultivated areas are between 0,2 to 3 hectares. In this context, collaborative mapping through open data platforms is one cheaper possibility to mitigate the lack of maps in Brazilian municipalities. The OpenStreetMap (OSM) platform emerges as promising because it has wide territorial coverage of high-resolution images, which makes it possible to view the communities on the local cartographic scale. This presentation has the aim to show the experiences of the Brazilian YouthMappers’ chapter Unificar Ações e Informações Geoespaciais (UAIGeo), in partner with Centro de Estudos Superiores de Tefé-Universidade do Estado do Amazonas - CEST/UEA, within mapping riverside communities in the Amazon rainforest. In its initial phase, the project received support from the Everywhere She Maps program, due to its women leadership role and goals of empowering young women in geospatial and technical skills. Globally, on average 35% of female students entering the university choose fields in science, technology, engineering, and math - STEM [2]. The Global Gender Gap Report 2020 shows that Brazilian women represent just 18% of employees in technological jobs, a percentage below the global average [3]. Additionally, according to a study that has analyzed OSM users and the manifested gender, by 2019 female participation reached 13% [4]. For this reason, this presentation emphasizes how important it is to engage and incentivize women’s participation both from external and local communities. Gender relations are important components of key forest-related issues, such as climate change and the differences in opportunities facing women in these contexts. However, there is little literature on forest and gender in Latin America, particularly in the Amazon Forest [5] The chapter have been coordinating a series of mapping activities focused on the municipality of Tefé and verified that volunteers have mapped so far 11.082 buildings in the Humanitarian OpenStreetMap Tasking Manager platform since last year. Together with local collaborators from CEST/UEA, chapter members validated some names of communities on one of Tefé’s islands. Chapter members carried out fieldwork in Tefé to know the local reality and some places that they had mapped. They also conducted studies in São Luís do Macari, a community that is located on an island in the middle of the Solimões River. Results of remote and fieldwork activities will be presented while at the same time emphasizing the importance of engaging and encouraging female students to link mapping and female empowerment. * [1] De Magalhães Lima, D.; Ferreira Alencar, E.

QGIS is one of the most used Opensource GIS software with some native functionalities to work with OSM data. Either with raster layer as a basemap, or with vector, QGIS can deal with OSM data. Depending on the amount of data to work with, the need to "refresh" the data (from the main OSM database), the extent of the coverage, different plugins or technologies are possible. This presentation will try to give an overview how it's possible to use OpenStreetMap data according to different situations (Geocoding, TMS/WMS, OverpassAPI, PostgreSQL…). The presentation will show how you can contribute to QuickOSM to add some default « mappreset » to QuickOSM on GitHub.

What is the state of the map in 2022 and how did we get here? Everyone who has used and contributed to OSM knows that the map is constantly evolving: new objects are added, existing data is adjusted and eventually gets deleted. In this workshop we want to explain and show hands-on how you can analyze mapping activity over time through the ohsome framework and how you can interpret the changes, e.g. in respect to data quality, and by combining the ohsome approach with other tools.

The OSHDB and ohsome framework have been introduced to the wider OSM community at State of the Map 2018 in Milan. Back then the first version of OSHDB has been released as open-source on GitHub. Here we want to give an update what has happened since then when it comes to uncovering the spatial-temporal dynamics of OSM mapping. Although other software tools like overpass(query language), iOSMAnalyzer(reports), osm2pgsql(database), osm2orc(amazon service) address this problem partially, none of them is able to provide the following range of functionality in one single integrated tool: easy reconstruction of historic geometric and semantic states of the data as well as spatial, temporal and tag queries. We want to provide an introduction how the ohsome stack (ohsome API, ohsome-dashboard, ohsomeHex, qgis/r/python-plugin, oshdb) can be used for such questions. Based on practical examples and hands-on exercises we've collected over the past years we want to enable the participants to understand the practical usage and enable them to run their own analyses. In this workshop we will show the various endpoints of the ohsome API and we will explain how we've used them in the past. Participants will learn how they can filter for OSM data based on tags, OSM data types (node, way, relation), geometry types (e.g. point, linestring, polygon) or changeset ids. As the OSHDB provides the full spatial and temporal access of the underlying OSM data set, from the state of a single point in time (snapshot) or down to the full edit history of single elements, data can even include indirect contributions and lossless geometric access. (So if you are interested in "broken" geometries we can provide these as well. (wink)) We want to prepare 3-4 hands-on examples. For these it would be good if participants can install QGIS in advance of the workshop. Example (1) will provide an easy entry point towards understanding how OSM changes over time. First, we want to explain how you can count the number of OSM objects, e.g. buildings, on a monthly basis for a given region based on the snapshot view. In Example (2) we want to investigate "re-tagging" activities. Re-tagging can be described as the systematic change of tag values, e.g. highway=unclassified to highway=residential. The example will show how we can detect such activities in OSM using the "groupByTag"-feature and will underline the resulting challenges such activities can have on OSM based metrics. Example (3) will focus on the so-called "contributions". These can be understood as the changes between two version of an OSM object. For instance, through this concept we can investigate how many new objects have been added to OSM. Maybe even more interesting will be the analysis of further contribution types such as "geometry changed", "tag changed", "deleted". Putting all this together can give us a good understanding of how OSM is expanding and maintained.

Across OpenStreetMap there are ways to get involved from working groups to events to boards. How can we increase and deepen participation across the world? What is the current state of engagement/governance in OSM? What do we need to do to improve? What are some of the lessons from other open organizations?

Proposed Outcomes -Inspire people to join play a bigger role in OSM - working groups, boards, governance -Engage a larger discussion about diversity, equity, and inclusion with a shared leadership approach -Infuse the OSM network with insights from other ‘open projects’ on their insights Notes We want to make this as accessible and inclusive as possible. Thus - calling it ‘governance’ won’t build participation. For years, there has been sessions on ‘working groups’ and ‘meet the board’ or meet ‘weeklyosm’. These are valuable, but we need to go wider and deeper. How can we learn about our shared network and build momentum in participation /engagement and leadership?

During the 2019-2020 pilot supported by Microsoft, 18 million building footprints were automatically extracted from satellite imagery for all of Tanzania and Uganda. HOT found that on average, mappers working without AI assistance could map between 1000-1500 buildings per working day. For areas with high-quality AI output, providing mappers with AI-generated building footprint suggestions increased this rate to up to 2500-3000 buildings per day approximately doubling the rate at which building data could be added to OpenStreetMap, which is the crucial link for making it available to the humanitarian information management community.

While doubling mapping efficiencies (100% efficiency gain) are promising, one of the greatest challenges is making sure data is converted from AI/ML to OpenStreetMap in a rapid yet responsible community-centric way (respecting existing data contributions already in OpenStreetMap). This project enabled us to take the ‘next step’ after receiving the building predictions from Microsoft by building better tools for data conflation. This is expected to dramatically reduce manual intervention. By doing this, human mappers can focus their time and skills on value-added activities: ground-truthing and validating predictions and adding local knowledge to the map not visible from satellite imagery (such as place names, location of key lifeline infrastructure, etc. We’ll describe our mapping workflow and progress updates for Kenya and Nigeria, and the specific challenges met with this dataset extracted through machine learning will be explained. Considering the growing availability of such AI-related datasets, we’ll review common errors and how we adapted to them and to other issues such as imagery offsets, heterogeneity of existing data and other context specific challenges. Eventually we’ll propose recommendations regarding this type of editing and aspects to consider before starting such imports and how to get the community involved.

Language barrier and the default to English puts non-English speakers at a systemic disadvantage throughout open mapping communities and humanitarian open mapping activities resulting in significant missed participation and impact. We held experimentation on language translations of key resources identified by collaborators coming from local OSM communities and we hope to share the findings in this talk.

We believe that language localization will enable inclusion and participation of underrepresented groups in mapping, dialogues and other humanitarian open mapping activities. We ran small experiments with local contributors to test how localisation of resources could work in the main languages of 3 priority countries (Vietnam, Madagascar, Mozambique) and we hoped its insights would inform a self-sustainable Localization Strategy for these communities and beyond. However, the documented findings are not sufficient due to challenges encountered (including communication and technical barriers, difficulty with monitoring and evaluation, among others) during the course of the research. Hence, opportunities and recommendations will be presented for future work to explore this theme. OSM Diary post on the launch: https://www.openstreetmap.org/user/arnalielsewhere/diary/397844

It’s easy to see how OpenStreetMap could be leveraged to improve the completeness and freshness of government geospatial datasets. So why aren’t all governments using OpenStreetMap? In the US, the ODbL license has prevented government agencies from using the data. Public Domain Map aims to resolve this (and other challenges) by providing a workflow that allows contributions to be used in both OpenStreetMap and public domain US Government databases. We will share the journey of Public Domain Map, how the project is bringing together US federal agencies and open source contributors to meet this goal, and how this might change how governments use OSM around the world.

The United Nations Global Service Center (UNGSC) is developing Virtual Reality applications utilizing OpenStreetMap data. Through a Virtual Reality (VR) pilot project, UNGSC aims to provide UN peacekeepers on the field with 3D digital replicas of the cities in which they are operating, building a sandbox that enhances operational planning with simulations. In order to develop such applications, OpenStreetMap buildings are collaboratively edited, validated and ingested. Field mapping and street-level imagery are also extremely important to add details to the rendered buildings. There could be the possibility to organise a live demo through VR headset.

Through the Virtual Operation Center (VOC) pilot project, UNGSC aims to provide UN peacekeepers on the field with 3D digital replicas of the cities in which they are operating, building a sandbox that enhances operational planning with simulations. Under the umbrella of the UN Mappers community, the areas of interest get mapped by means of Tasking Manager projects. Differently from other building mapping campaigns, those are different, as higher quality of the footprints is needed, as well as better placement at the ground floor level and understanding of tall buildings. Furthermore mapping can be complemented with field mapping with street-level imagery as well as smartphone applications, in order to add details on the buildings characteristics as height, levels, roof shape, color and material. After validation of all the edited data, the buildings are ingested into Virtual Reality software development tools as ArcGIS CityEngine and Unity to develop the sandbox application accessible through VR headset. Buildings get eventually rendered utilizing OSM tags which define the 3D model of each object. The activity has been already tested and developed in Mogadishu, Somalia, and Tripoli, Libya, where the mapping took place engaging with the local communities (OSM Somalia and OSM Libya). At the end of the talk, there could be the possibility to organise a live demo through VR headset.

Human factor is one of the most crucial elements in crowdsourced mapping. This research explores how human bias affects the mapping process and whether such effects can be mitigated through targeted training with a behavioral experiment. The experiment uses a two-group randomized design. The treatment group receives more advanced training than the control group. There are two goals for the experiment. First, we aim to identify the common types of bias that amateurs from a specific demographic community have when using OSM. Second, we plan to explore whether training is helpful for reducing those biases and improve the quality of mapping.

OpenStreetMap (OSM) is one of the VGI platforms that has been curated primarily by volunteers, which indicates that the demographic differences of the backgrounds of volunteers might affect their understanding of mapping and their mapping behavior. For example, contributors with varying skills and experiences of mapping and GIS software might choose different objects to map and trace them in different levels of detail. There is a wide range of factors that could have an impact on how and what individual contributors choose to map: age, gender, expertise, education, income, etc. This study focuses on digging into the mapping behavior of a specific demographic community - residents from Singapore. We have observed changes in terms of tagging and editing behavior in OSM before and after different levels of training. This study has important implications for OSM mapping, especially platforms such as HOTOSM which largely rely on faraway amateur curators to provide up-to-date geographical information of a specific area in case of events such as wars, natural disasters, crimes or humanitarian emergencies.

OpenStreetMap has many details about streets, but applications rendering or simulating lane-level detail face many challenges: determining lane properties along one street, calculating geometry of streets and junctions, handling motorway entrances, dual carriageways, dog-leg intersections, placement tags, and parallel sidewalks and cycleways. osm2streets is a new effort to produce a cleaned-up street network graph with geometry. It's a Rust library, designed to be integrated with browser apps like iD or native/Java apps like JOSM. The goal is to consolidate community efforts to solve these data transformation problems, and to produce high-detail vector maps and apps for improving lane tagging with immediate visual feedback.

RapiD is the OpenStreetMap editor that enables users to access a wide variety of shared open data and a machine learning generated predictions that can bring new detail to the map. In 2022, the team at Meta upgraded RapiD to enable users to validate and verify Mapillary detections from images and add data to OpenStreetMap. Join us in an instructional workshop and mapathon where we will learn how Youthmappers in Sierra Leone are using Mapillaryto map the power grid across the country, and how the same workflow can be applied to map electricity availability and lighting around the world, anywhere users capture Mapillary and utilize RapiD to enrich OpenStreetMap.

Goals: - Introduce the project for utility pole/power line mapping in Sierra Leone - demo how to capture Mapillary imagery - walkthrough on how to use RapiD for adding utility poles and street lamps - guided mapathon with focus on Sierra Leone and option to replicate anywhere the participant wants, such as their hometown Logistics: - projector screen - classroom environment good for lecture + laptop work - bring your own laptop + mobile phone - access to wifi needed (we can try to hotspot via my phone) - we will try to provide a few laptops, but if the venue can provide any it will be helpful for using OSM iD/RapiD

What must be mapped to make routing for prams and wheelchairs practical? Three years ago, the local meet-up in Dortmund, Germany, started a campaign to make step-free routing available for the general public. The lessons learned mean that such routing is possible, but there is a lot missing to map - both in Dortmund and in all other parts of the world. Map the essential where fellow mappers are sparse. And codify the full ground truth where the passion allows it. I hope to encourage mappers for the quest to get their neighbourhood ready for wheelchairs, prams and all the other pedestrians!

Routing for pedestrians is a much broader challenge than the well-known car routing. Cars all over the world are mostly uniform, but pedestrians vary widely in their capabilities. This means that a lot of details that a sportive person might not even notice can be literally a roadblocker for people with prams, for wheelchair users or simply lesser-abled people with not enough strength for a complete stairway. Becoming a father has been a good opportunity to check in practice what is and what is not feasible for a pedestrian with a pushed vehicle. It turns out that the first step is to get aware of the various kinds of obstacles that get in the way. Beside the obvious steps and kerbs, there are impassable surfaces, too narrow or too steep sections. Or simply sidewalks missing completely on the ground. As of now, OpenStreetMap data does not even suffice to figure out where one or both sidewalks actually exist. This puts into perspective the discussions about how to map best details of both detached ways and sidewalks. A couple of tagging approaches are compared to allow educated guesses which level of detail will allow for good results rather in weeks and months than in years or decades. I even dare to give suggestions what tagging practices we should additionally adopt to be able to map faster. The background of this talk is an initiative from the Dortmund meet-up: For the large event Kirchentag 2019, we mapped at least the city center sufficiently well for wheelchair mapping. The whole city with its 1500 km streets has turned out to be simply too much. Given that a city with a local meet-up is in a relatively good position to be mapped, it was no surprise that also elsewhere the data is simply not yet good enough for wheelchair routing. The hope is that simple suggestions what helps is getting more traction than a sophisticated mapping hierarchy.

Sparked by concerns about OpenStreetMap's role in how the public accesses and recreates on protected lands, OpenStreetMap US volunteers, navigation app developers, national agencies and public land managers formed the OpenStreetMap US Trails Working Group in 2021. Bringing together a diversity of perspectives on trail mapping practices, trail safety, and protecting the environment, this group is working to address on-the-ground challenges, tagging schemes, authoritative data, and other topics related to mapping trails in OSM. Learn how this group is collaboratively developing solutions for responsible trail mapping in OpenStreetMap.

OpenIndoor is an open source SaaS that uses OpenStreetMap indoor data to display a 3D graphical rendering of building interiors. The resulting map offers a gamified experience to meet different types of needs: indoor navigation, data representation, immersive tour etc. We will discuss how we use the available open data and the Maplibre engine to address these different use cases.

In this workshop, you'll learn the basics of setting up your own mapcomplete theme. After a short introduction, explanation of some common pitfalls and a technical explanation, you're invited to open up your laptop (or tablet) and can try it out yourself while I'm around to answer some questions.

If you ever wondered how you can quickly create an OSM-editor geared towards a specific topic, this workshop is for you. First, a small introduction to what a good theme is will be given; together with some common requests and best practices. Afterwards, the technicalities of getting started are explained. The idea is to have a hands-on workshop, where one can give it a try immediately.

Follow the OSM journey of the Médecins Sans Frontières (MSF) from a mapathon in Berlin in 2014 to creating and contributing geodata for numerous MSF operations through the Missing Maps project. This talk will be about how MSF uses OpenStreetMap internally and how we contribute through remote and field mapping. We will also share the lessons learned and reflect on the biggest challenges for MSF in creating and using the OSM data.

The OpenStreetMap journey of Médecins Sans Frontières (MSF) started in 2014 with a mapping party in Berlin and field mapping in Lubumbashi. Eight years later, OpenStreetMap is the reference geographical dataset for most of MSF operations on the ground. OpenStreetMap has been used in public health interventions, disease outbreaks, mortality studies and to support large logistical operations. Still every day we are learning how geographical information can support us in doing our job better, in reaching more people, in saving more lives. MSF is not only using OpenStreetMap, but it also actively contributes to the map through the Missing Maps project launched in 2014 together with the American Red Cross, the British Red Cross, and the Humanitarian OpenStreetMap Team. Since then, MSF has trained dozens of Missing Maps champions, co-organized hundreds mapathons and involved thousands of volunteers in some 30 countries. In this presentation we will talk about how MSF uses OpenStreetMap internally and how we contribute through remote and field mapping. We will also share the lessons learned and reflect on the biggest challenges for MSF in creating and using the OSM data.
