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.
Day 2
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!
