WaterwayMap.org displays how waterways in OpenStreetMap (OSM) are connected, helping mappers find and fix tagging mistakes. The site maintains a river database based entirely on OSM data and is used as a reference source by entities like Wikipedia. The grant covers approximately one year of web hosting costs for this service. (Read more.)
Map Review Team
The Map Review Team project supports teams of mappers in collaboratively reviewing changes to the map within a specific geographical area. Its grant will support integrating with existing OSM tools and APIs, such as WhoDidIt and OSM Notes, to gather event data. A key feature is the introduction of an “approval” status, allowing teams to focus their efforts on changes that have not yet been reviewed by another team member. (Read more.)
Field Tasking Manager
HOT (Humanitarian OpenStreetMap Team) will use their grant to enhance their Field Tasking Manager (FieldTM) tool. Their development focuses on improving OSM integration by creating compatible survey forms and developing a robust conflation workflow to merge field-verified data with existing OSM data. The plan includes partnering with a local OSM community/university chapter in a priority country to test the tool and field-verify a city’s data. (Read more)
UseOSM
Developed by the Unpatterned Lab team, UseOSM hels discover unused opportunities in OSM data. Its platform is live at useosm.org but is not fully operational. The launch is projected to be in January 2026. (Read more)
OSM Apps Catalog
The OSM Apps Catalog helps people discover apps that use OpenStreetMap. The grant will be used to redesign the landing page to look more like an app store, including: What’s new, daily featured apps; Language support; new categories and improved search; and a support/donate (to apps accessed) function. View the current platform at osm-apps.org. (Read more.)
StreetComplete
The StreetComplete team will use the grant to help encourage users to be more involved in the OSM community. They are working on ways to notify about nearby community events, list local community channels, and integrate Weekly OSM news. (Read more)
OpenStreetMap Stats Generator
OpenStreetMap Stats Generator reports stats about user contributions in mapping campaigns. They will use the grant to revamp the project after some years of not being maintained. The’ll move from Planet files to Parquet and are targeting SotM 2026 for the working version release. (Read More)
Following the call for applications launched in April, we are thrilled to announce the results of the State of the Map 2025 Travel Grant Programme. This initiative aims to support contributors who may face challenges in attending the global OpenStreetMap conference, which will be held in Manila, Philippines, from October 3rd to 5th, 2025.
The Travel Grant Programme is a part of the OpenStreetMap Foundation’s ongoing commitment to making State of the Map more inclusive, diverse, and globally representative. By providing financial assistance, the programme enables community members from various regions and backgrounds to participate in the conference, both in person and online.
This year’s call for applications received an extraordinary response, with over 180 applications submitted by mappers and community members from more than 35 countries. The majority of applicants hailed from Asia and Africa. Notably, approximately 78% of all applicants were students or early-career mappers. However, only about one-third of the applicants identified as female. Furthermore, over 80% of the applicants had never attended a State of the Map event before. These figures underscore the ongoing success of the Travel Grant Programme in reaching new and emerging OpenStreetMap communities, particularly in the Global South.
Applicants represented a wide spectrum of mapping experience within the OpenStreetMap ecosystem. For example, using one of the multiple selection criteria (the number of changesets), we could see the wide spectrum of OSM mappers who applied to the call. Around 20% of applicants were new or had minimal mapping experience (fewer than 10 changesets), while approximately 30% were in the intermediate range (100–2000 changesets), showing consistent engagement and growing contributions. Notably, nearly one in four applicants were highly active mappers with more than 2,000 changesets, demonstrating deep, ongoing involvement in OSM projects. Overall, the applicant pool combined new contributors eager to join the global community with experienced mappers making strong local impacts, reflecting the programme’s success in attracting a balanced mix of experience levels.
After careful evaluation, 37 grantees were selected to receive support for travel and participation. However, only 25 of them were able to attend the event in Manila. The selected applicants represent a diverse range of grant categories, from £215 to £1000. The allocation of funds was based on factors such as the distance traveled, regional cost levels, and individual circumstances.

The selection criteria employed in the call successfully achieved the objective of increasing the diversity of participants at SotM. A total of 17 female and 16 male grantees attended, resulting in a nearly gender-balanced group. Notably, there was strong representation of women within the OpenStreetMap community. Furthermore, 90% of the grantees hailed from Africa and Asia, underscoring the Foundation’s unwavering commitment to equitable global participation.
The diversity of applicants and grantees reflects the remarkable progress made by the OpenStreetMap community in expanding access to global events. Thanks to the Travel Grant Programme, many first-time attendees will now have the opportunity to share their experiences, projects, and local insights with the global OSM community in Manila.
The OSM Foundation and the State of the Map organizing team warmly thanks all applicants, reviewers, and sponsors whose support made this year’s programme possible. We look forward to welcoming everyone to State of the Map 2026 in Paris!

On 4-6 September, we attended the State of the Map Latam 2025, the Latin American OpenStreetMap conference. This year marked the 7th edition, taking place for the first time in Colombia, in the vibrant city of Medellín. Medellín has been a model of urban transformation and community-led projects in the last couple of decades, with the conference venue being a perfect example of this. The Parque Biblioteca San Javier was the first Library Park to be built, a project aimed at bringing green, cultural, and educational spaces to the less affluent districts of the city.

Day 1
Day 1 started with the welcome speech by Juan Arellano and Andrés Gómez from the Organizing Committee. Afterward, we enjoyed a live performance of traditional Colombian dances, courtesy of Ballet Nacional El Firulete.
We at the OSMF had the privilege of conducting the first keynote presentation. Most attendees were unfamiliar with the Foundation and its role prior to the event, so attending events like this is a great way to spread awareness and diversify our membership.
The second keynote was presented by TomTom, one of the two event sponsors (the other being Geoapify). We thank all the sponsors who make this and other community events possible, as well as for their continuous support of the OpenStreetMap project.

After lunch, the program continued with the talk from Trufi, on how OpenStreetMap can be used for mapping Public Transport, and become the foundation of MaaS in the Global South. Informal transport is a common occurrence in many parts of the world, yet knowing where these routes go can be a challenge for both users and planning authorities. The day continued with a discussion on the future of Humanitarian Mapping after the stopping of USAID funding. Parallel to these two sessions, attendees could also take a guided visit to the neighbourhood around the event location, accompanied by social entities.
To conclude the day, we took part in the General Assembly of OSM Latam for three hours, which included a lengthy discussion on the challenges both the region and OSM face in the future. Following the official program, we continued to have dinner together and celebrated the 15th anniversary of HOT.
The second day featured a diverse range of talks and workshops, with up to four sessions running in parallel! Since it is impossible to discuss all of them, we encourage you to explore the program and contact the authors of the talks of interest to you.
The topics discussed during the day were categorized into Governance and Community, Risk Management, OSM Data, OSM Tech, Informal Settlements, Amazonia, Academic Talks, and Workshops. Community partnerships are a cornerstone of the Latin American mapping community, where making a social impact and strengthening the social fabric are among the most important aspects of mapping, a characteristic that is very present in the day’s talks.

From gender representation in the OSM community to localized geocoding, from social justice slum mapping to student training and engagement, from indigenous mapping to infrastructure and risk mapping, from storytelling to public transport maps. A blog post cannot do justice to the use cases and social transformations the Latam community is creating. An engagement that is possible through the power and openness of OpenStreetMap.
We invite you to review the slides from each talk and workshop in this Commons category.

After the event, we continued on to socialize and have dinner together.
Day 3
Day 3, the final day of the conference, started strongly, with four parallel talks already scheduled in the first allocated slot. This day featured more technical talks compared to day 2, with topics categorized into the following areas: Public Transport, OSM Tech, Governance and Community, Trees and Forests, Pedestrian Mapping, OSM Data and Use Cases, Academic Talks, and Workshops.
From OSMCha to OpenHistoricalMap, from OSM and Wikidata integration to mapping with OSMTracker, from sidewalk mapping to Python, and from YouthMappers to Government collaboration. The exchange of technical knowledge is an important way to connect ideas and use cases with the tools that can bring them to life. Additionally, the engagement of the younger generation and governmental entities is crucial to the long-term sustainability of the data in the region.

A personal highlight of the day was the drone imagery workshop. Most Latin American countries lack high-quality government mapping imagery and, therefore, must rely on satellite imagery. But mappers took matters into their own hands to produce high-quality drone imagery to meet their surveying needs! And while the workshop was underway, we used the same drone to take the group pictures of the event; we were quite a crew!

The day then concluded with the event’s closure, which included the election of the venue for SotM Latam 2026. There was only one bid, but the attendees agreed it was a strong one. So see you in Mexico City in 2026, ¡órale!

Hello all! My name is Pablo Brasero Moreno, a software engineer and long-time enthusiast of Open Source Software and Open Data. I am honoured and grateful to have been selected by the OSMF as Core Software Engineer, thanks the funds provided by the Sovereign Tech Agency.
At a personal level, I grew up in Seville, Spain. In 2004 I moved to the UK and, after living for many years in London, England, now I’m established in Belfast, Northern Ireland. In my own time I explore Northern Ireland with my family, read sci-fi novels, listen to heavy metal music, attend concerts, play bass guitar (badly), and try to learn languages (even more badly, currently attempting Mandarin Chinese). Did I mention I have a B1 certificate in Esperanto?
I have been involved in some capacity with Open Source Software since I first installed Linux in my computer in 1998, first contributing with Spanish translations (over email!), and later taking part in the OSS explosion brought by the creation of GitHub. I have worked with many technology stacks over my career, but for a long time the primary one has been Ruby on Rails. I have used Ruby in many environments, from helping clients bootstrap businesses out of napkin sketches, to participating in the architecture and growth of banking applications. Since 2019 I am a freelancer, and I cannot but feel so lucky to have been available at the time when OSMF announced this position.
Without being a huge contributor to OSM, I was aware of it at least as early as 2015, when I made my first edits while visiting Mexico. In the last couple of years I have started mapping playgrounds, as that strikes a balance between my interest to contribute and my family’s patience to wait for me while I fiddle on my phone.
I am not here to dictate what features should exist in the the OSM website, or what specific issues should be fixed. I am here to learn about the needs of the community, relieve the workload of the volunteers, support contributors new and old, provide reviews and guidance on software engineering questions, and overall help bring our collective vision of OSM to fruition.
You will be hearing from me soon, in the form of GitHub comments/issues/PRs, working with Minh Nguyễn with news and summaries related to development of the platform, talking to many of you directly in order to understand your points of view, and generally anywhere where I can help.

by Minh Nguyễn Core Software Development Facilitator, OpenStreetMap Foundation
In June, I had the privilege of representing OpenStreetMap as part of the Sovereign Tech Agency’s delegation at UN Open Source Week in New York City. Joining me was Sarah Hoffmann, who maintains several well-known OSM software projects. This was a unique opportunity to raise OSM’s profile among global institutional supporters of open source projects and promote best practices for fostering and sustaining authentic open source communities.
Among the open source projects represented at the event, OSM stands out as an open data project, giving us a special perspective on issues of governance and community-building. At the unconference-style “Maintain-A-Thon”, Sarah shared some of her deep experience as maintainer of Nominatim in discussing how to create accessible entry points for new contributors. A few steps away, I joined open source maintainers from around the world as we discussed our challenges in internationalizing our projects and communities to serve a more global audience.
(Meanwhile, Wikipedians onboarded a large group of new contributors at an editathon across the room. Maybe in the future we can carve out some space for a mapathon too.)
The UN’s Trusteeship Council room is full as an International Telecommunication Union official speaks before attendees at DPI Day.
As the discussion came around to topics such as contributor retention and developing governance models, I was struck by the familiar challenges that our various projects have faced, even though they’re in different fields and at such different stages of maturity.
How do we accommodate volunteers coexisting with paid developers and individuals coexisting with institutional partners?
How do we build a pipeline that transforms “takers” into “makers”?
How do we ensure that the community feels heard without allowing the project to fall victim to analysis paralysis?
It was fascinating to hear about the approaches that larger projects with institutional backing have taken, but our grassroots, decentralized structure would likely require some extra creativity. At least we’re in touch and can learn from each other going forward, since there are no magic solutions.
Just like at any OSM conference, the most interesting part was the hallway track. We had the privilege of meeting a number of representatives from open source program offices (OSPOs) in the public sector, civil society, and academia. Some had heard of OSM but only knew us as a map data vendor or some sort of alternative to Google Maps. It’s always fun to meet people who think they know about GIS and maps and introduce them to the very concept of a map rooted in a community. University OSPOs were particularly interested in our story, as OSM is a whole constellation of projects that use a variety of technologies. Here’s hoping something comes of that.
In the meantime, we have plenty of technical debt as well as some low-hanging fruit for improving how the projects run day to day. I’m excited about the opportunity to bring in a Core Software Engineer who over time can hopefully complement the irreplaceable efforts of our volunteers. Whether you’re a coder or not, there’s a place for you to thrive in OSM.

Did you miss the call for general and OSM Science presentations? Fret not! You can still present your project and initiatives at State of the Map 2025! The Call for Posters for SotM 2025 is now open!
Your poster could show how well your community is mapped. It could be a new beautiful style or a map. It could be a community project or statistics, or a poster explaining and inviting people to OpenStreetMap. The important thing is that it is about OSM. We also welcome academic posters on research around OpenStreetMap data.
Please send an email to sotm [at] openstreetmap.org with a description of your poster. For example, the background of the project or whatever you consider important to mention in the context of the poster – all that you would tell people if you show them your poster. We will publish this text together with the poster on the SotM website. Please also mention the filename of the uploaded poster in your email, so that we can know which of the uploaded posters is yours.
Timeline
Deadline: 15 September 2025
The SotM team hopes to shortlist up to 20 posters that will be published on our website and some other SotM channels under CC BY SA 3.0 (or later)
