Mapping campaigns
- Séverin Ménard shared a new blog post
►
about the ongoing building damage mapping in Mayotte, with statistics for each of the territory’s 17 communes, including hourly updated pie charts showing mapping progress and the damage classes. The preliminary results reveal the heterogeneity of the damage across the communes and show that the north-eastern coasts were not necessarily the areas most severely affected. - The newly added Mastodon account ‘OpenStreetMap Wiki Proposals’ toots when proposals are open for voting, with its latest toot being: ‘A new OpenStreetMap Wiki proposal aims to improve power circuit routing by introducing standardised relations for circuits and line sections, enhancing electrical grid modelling’.
Community
- Peter has calculated the year when the sun first stopped setting on the British Empire, based on the boundaries in OpenHistoricalMap (we reported earlier).
- Peter Brodersen has developed a prototype route planner for Denmark that avoids roads named after men. It was made possible by using the OSRM routing engine and the Wikidata entries referenced by the
name:etymology:wikidataOSM tag. - After logo submissions and a community voting process, Unique Mappers Network has unveiled the official logo for State of the Map Nigeria 2025.
- Faced with the limited storage capacity of his older Garmin device, which can hold only one map at a time, Pascal Neis has developed custom minimalist Garmin maps based on OpenStreetMap data to ensure they remain small enough to fit.
- In a recent instalment of the Mapper Diaries vlog series, Gregory Marler talked about his participation in the second UK quarterly project of 2025, a healthcare-themed mapping campaign, by mapping neighbourhoods in Dundee City, Scotland.
- Christoph Hormann offered his views about the ways diverse cultures collaborate within OpenStreetMap, highlighting the challenges that arise from these cross-cultural interactions.
- KhubsuratInsaan’s diary entry reflected on mapping in India, highlighting the difficulty of identifying house numbers. The comments discuss whether street plans may be used for OpenStreetMap.
Local chapter news
- The OpenStreetMap US May 2025 newsletter has been published. The highlights are the improvements to the OSMCha, the support program for participation in the SotM US 2025 and the celebration of the OSM US’s 15th anniversary.
- Oliver Rudzick and Katja Haferkorn released
► a report on the 23rd FOSSGIS-OSM Community Meeting, held in May 2025.
Events
- OpenStreetMap contributors are organising
a collaborative mapping workshop called Kartenwerkstatt Augustusburg, to improve regional map data and foster community engagement in Augustusburg, Germany.
OSM research
- HeiGIT reported that a new paper was published in African Transport Studies. This study investigated the impact of school sessions on traffic congestion in Nairobi using openrouteservice, an open-source routing engine that utilises OpenStreetMap data to model road networks. Results highlighted how children’s mobility needs are often overlooked in transport planning.
Maps
- The author of Maps Interlude presents various socio-economic factoids on maps, with their latest showing the origins of Havard’s international students during the previous Trump presidency in 2018.
- Christoph Hormann introduced another extension to his Musaicum satellite image mosaic coverage, which includes the European Arctic islands: Svalbard, Franz Josef Land, and Novaya Zemlya.
OSM in action
- The World Heritage Journeys Europe portal has adopted OpenStreetMap and Mapbox for their maps of world heritage catalogued by UNESCO and the European Union.
- Where Filmed’s ‘Filming Places Near You’ feature lets users discover nearby filming locations via an interactive web map powered by OpenStreetMap and Leaflet.
Open Data
- Ralph Straumann commented on grid’s interview with Jennings Anderson, a software engineer at Meta, noting that it’s overall an interesting – albeit clearly insider – perspective on the Overture Maps Foundation, OSM, and the evolution of geodata in general.
Software
- [1] Rphryin published his first JOSM map style: LastUpdated. It displays the last update time of each OSM way shown on the screen. This is useful for checking whether a particular mapping area has been updated recently.
- Andrii Holovin has developed osm-diff-state, a tool designed to find the state file corresponding to a specific diff in the OpenStreetMap minutely/hourly/daily replication feeds.
- The team behind Contour has launched a browser-based GIS platform that uses natural language commands to perform spatial analysis and mapping, aiming to simplify traditional GIS workflows and make spatial tools accessible without coding.
- András Zlinszky explained how to load Sentinel-2 true-colour satellite imagery into the Locus Map app using its Web Map Service feature.
- HeiGIT, in collaboration with the Federal Agency for Cartography and Geodesy, have worked on the LaVerDi Project, which integrates freely available satellite data with crowdsourced OpenStreetMap data to support continuous, large-scale land cover monitoring and improve the detection of landscape changes in Germany.
- To celebrate its 15th anniversary, OsmAnd has published some of its growth statistics.
- GeoObserver introduced ► Radinfra.de, a new platform that visualises Germany’s cycling infrastructure using open data and user-friendly maps.
Programming
- Researchers at the University of Freiburg have developed Loom, a tool for efficient multi-modal route planning using OpenStreetMap data, enabling detailed and customisable transport network analysis.
- OMP explained how they built a custom OpenStreetMap-based map service using mbtileserver.

- Jake Low explained the latest upgrade to OSMCha, highlighting the performance improvements achieved by building augmented diffs instead of using Overpass queries.
- The Panoramax mobile app v1.7.1 has been released. The app is now available on F-Droid and is being prepared for iOS. Highlights of the new changes: app info is added to the EXIF data of uploaded pictures and there is a new settings page and splash screen.
Did you know that …
- … there’s an OpenStreetMap Bluesky feed? It allows you to see posts featuring the hashtags #osm and #openstreetmap.
- … you can open a random OpenStreetMap note from any country of your choice?
- … the OpenStreetMap API has a rate-limiting feature that prevents new users from committing large, potentially damaging changesets? After it was implemented in the backend, some user-facing apps, such as iD, had to make adjustments to support this change. As a result, users running older versions of the editor may find their large changesets disappearing into thin air without any clear explanation or error message.
OSM in the media
- Game developers have integrated OpenStreetMap data into simulation games like City Bus Manager and Global Farmer, enabling players to build and manage real-world-inspired transport and farming systems while encouraging contributions to improve map accuracy.
- Gregory Thomas, of the San Francisco Chronicle, reported that Megan Gardner has ridden every publicly accessible road in San Mateo County – a feat spanning 2,800 miles. To accomplish this feat, Gardner relied on Wandrer, a social mapping platform built on OpenStreetMap data. The app turns everyday walks, hikes, and bike rides into personal quests, awarding symbolic points and rewards to users who go the farthest. Participants can track their progress and compare standings on leaderboards showing who is covering the most ground and where.
Other “geo” things
- The mapShare creators have launched a platform that lets users share and discover custom Google Maps, helping travellers find curated local recommendations such as sightseeing spots and photo locations, with strong initial coverage in Japan.
- Rainer Follador has developed ‘delta-relief’, an project designed to enhance the visualisation of SwissTopo’s LiDAR data by highlighting subtle terrain variations for easier interpretation. It has been implemented as an interactive online map, with a portion of the data from eastern Switzerland now available to the public at lidar.cubetrek.com.
