Community
- Adrian Shobrooke shared several insights into the validation process within the context of OSM humanitarian mapping activities.
- Giopera outlined the process behind the creation of several OSM-related logos for the Italian community, which incorporated visual elements derived from OSM data.
- Bastian Greshake Tzovaras shared how he used Every Door and CoMaps for mapping and surveying while trekking in Peru, thanks to offline features and battery saving possibilities.
- Nicole Siggins (MapSwipe governance team) and Benjamin Herfort (HeiGIT) gave a talk at State of the Map Europe about the current state of MapSwipe and its future in OSM. The talk explored the possibility of MapSwipe becoming its own OSM editor, able to add attributes to existing OSM features, as well as the potential to utilise human validated machine learning to add building footprints from fAIr (HOT’s AI modelling tool) to OSM directly. After reading the write-up, you are invited to share your thoughts about these propositions in the accompanying diary post.

OpenStreetMap Foundation
- The Operations Working Group is planning to host a copy of OpenStreetMap Spyglass, formerly OSM X-RAY. The goal is to replace the current data layer view on openstreetmap.org and you are invited to join in this effort by answering the public call for help published on the OSM Community forum.
- Fastly reported that the OpenStreetMap team has joined its Fast Forward programme to address its content delivery demands, relying on Fastly’s CDN to support raster tile generation, while deploying tailored Varnish Configuration Language rules to secure its systems, particularly in response to aggressive and irregular traffic linked to AI data scraping activity.
Local chapter news
- The OpenStreetMap US November 2025 newsletter has been released.
Events
- Submissions for the Geospatial devroom at FOSDEM 2026 are currently open and you can submit your contribution by 1 December using the Pretalx. The event will take place at the ULB Solbosch Campus, Brussels, Belgium, 31 January and 1 February 2026.
Education
- Anne-Karoline Distel published on Mastodon about her video that explains how to extract non-obvious data from OSM.
OSM research
- Rizaldy Utomo, of Carnegie Mellon University, has developed the PGH Transit Atlas, an interactive web dashboard that uses OpenStreetMap data to illustrate travel patterns across Pittsburgh Regional Transit bus services and the POGOH bike-share network. This study offered a series of policy recommendations aimed at improving coordination and integration between the two transportation systems to enhance overall transit efficiency.
- According to a study published in Nature Cities, OpenStreetMap data was successfully used to systematically analyse and score 23,477 parks across 35 global cities for their ability to support health-promoting activities, demonstrating the practical value of OSM’s detailed tagging system for large-scale urban well-being research.
Maps
- [1] Local newspaper the Oxford Clarion featured an OSM-based map of Oxford college cats.
- Pascal Neis is participating in the #30DayMapChallenge with a November 2025 update to his ‘Unmapped places of OpenStreetMap’, which highlights settlements that may lack basic mapping in OSM.
OSM in action
- The Decolonizing Southeast Asian Sound Archives project has made Pratinada, a website that provides access to several rare musical collections from Southeast Asia held in Europe. The website uses OpenStreetMap data to visualise the location of each sound archive.
- Rutometro, Trufi’s first multi-city app, uses OSM public transport routes from eight cities to help fill Mexico’s mobility gaps.
Programming
- Andy Townsend has developed a new OSM Shortbread vector map style, with a slightly less beige appearance than the style hosted on the OSM website, and he explained how to install it on a web server.
Releases
- CoMaps has released version 2025.11.19 of their map and navigation app for iOS and Android. Beyond updating OSM data to 16 November, this release includes a routing option to avoid paved roads and support for many new POIs, amongst other features.
- Iaan Dess is testing a new changeset viewer and query tool. The aim is to match some of OSMCha’s capabilities but with faster, simpler queries and a more user-friendly interface. Feedback from the community is welcome!
Did you know that …
- … the IHE Delft Institute for Water Education under the auspices of UNESCO annouces webinars on their website? You can also follow them on their GIS OpenCourseWare education platform (we reported earlier) and Mastodon.
- … OSM Relatify is a web app to easily edit the routes and stops of bus routes?
Other “geo” things
- Hans van der Kwast posted on LinkedIn about a map he has created for the #30DayMapChallenge, highlighting place names and other data about copen ► , relating to locations in the Netherlands, Germany, and Poland, showing how these legal instruments, which laid out the mutual rights and obligations between land reclaimers and landowners during the ‘Great Reclamation’ during the 12th and 13th centuries, leaving an enduring mark on the European landscape.
- Eita Horishida has updated the page about PLATEAU ► (Japan’s 3D city model, which aims to create digital twins of Japanese cities), including case studies and examples of implementation in the real world. Taichi Furuhashi, president of MAPconcierge, presented a keynote about this project at the State of the Map 2025, held in Manila (Philippines).
