- [1] With Spieli, m_fuhrmann has launched a new, user-friendly web map for playgrounds. The project is based on a fork of the ‘Berlin Playground Map’ and is firmly committed to an open ecosystem. While the playground data comes directly from OpenStreetMap, images are integrated via Panoramax and reviews via Mangrove Reviews.Particularly noteworthy is the technical architecture: Spieli is designed as a federated network of independent data nodes, enabling decentralized hosting and high scalability.For parents, the site offers helpful filters (e.g., by flooring type or accessibility) as well as suggestions for nearby points of interest (such as ice cream shops 🍦).Mappers benefit from integrated data quality assessment and direct links to MapComplete, making it easy to improve the data.
The project is currently seeking active support: Anyone with resources to spare is invited to host their own data nodes (https://mfuhrmann.github.io/spieli/) (e.g., for additional federal states or abroad). Discussion is possible via Matrix (https://matrix.to/#/#spieli:matrix.org), and the source code is available on GitHub (https://github.com/mfuhrmann/spieli).
- Christoph Hormann continued an in-depth discussion on non-locality in tiled rule-based map rendering, building on an earlier article that helped renew interest in OSM-Carto development.

- Bayreuther Tagblatt used ► an OpenStreetMap-based map to visualise road closure areas related to the 10th ‘Mainauenlauf’ running event, scheduled to take place on Sunday 14 June 2026.
- Niederrhein Nachrichten used ► an OpenStreetMap-based map to highlight parking areas available for visitors attending the Kleve Children’s Festival, scheduled to be held at the Kleve Zoo on Sunday 14 June.
- FerryGoGo helps travellers explore ferry routes worldwide through interactive maps, local route guides and practical advice built around real journeys by sea. It uses OpenStreetMap and shows ferry routes, ports and connections across each country.
- Phystech Mission have used an OpenStreetMap-based map to visualise the locations of technology companies and research institutes where graduates of the Moscow Institute of Physics and Technology are employed.
- Mediazona, BBC Russian Service, and a team of volunteers have created an interactive map showing the geographic distribution of confirmed Russian military casualties in their war against Ukraine. The dataset is compiled from open sources, including obituaries, media reports, local government publications, and other publicly available records, while the basemap uses OpenFreeMap tiles generated from OpenStreetMap data.

- Editora IVIDES ► has published a Swahili translation [sw] of Tout savoir sur la licence ODbL: la licence d’OpenStreetMap pour cartographier en commun, originally written in French by the Fédération des pros d’OSM, Kila Kitu Unachohitaji Kujua Kuhusu Leseni ya ODbL. The translation from English into Swahili was carried out by Hemed Lungo and Tatu Sultan Lungo (Tanzania) and edited by Raquel Deziderio Souto, who wrote about this on LinkedIn.
►Software

- Marina Petkova and François Lacombe have authored ► an article ‘Tracking and Promoting Contributions to OSM with Podoma’. Podoma is a programme for monitoring contributions to OSM, allowing users to measure and visualise activity related to a specific topic or area (we reported earlier).
Programming
- Timo Roest posted, on LinkedIn, about a custom PySpark data source to read .PBF files, seamlessly integrating osmium-powered OSM data ingestion into the Spark ecosystem. He explained how it works, and worked through a refresher on OSM data structures and why parsing them is a challenge.
Releases
- A new release of OSRM, version 26.6.1, is now available. Users can try out the updated demo ahead of its integration into the official front end.
- Alexis Lecanu has released Baba version 1.22.0, for contributing to Panoramax on Android, featuring several feature additions and bug fixes.
OSM in the media
- Danmarks Radio, Denmark’s national broadcaster, used an OpenStreetMap-based map to illustrate a major railway disruption caused by a damaged overhead power line near Sorø. The disruption was believed to have occurred after a train’s pantograph became entangled ► in an overhead wire, forcing rail services between Ringsted and Slagelse to stop.

- Patty Heyda outlined the concept of ‘counter maps’, describing them as cartographic reinterpretations that challenge established assumptions and broaden dominant narratives to include previously excluded perspectives. As mapping becomes increasingly shaped by political interests, remapping practices are presented as a way to expose underlying systems of power to public view. The concept has also influenced activists, who use counter mapping to re-integrate previously omitted information into mainstream representations.
- YellowMap ►, a company based in Karlsruhe (Baden-Württemberg, Germany) is sponsoring ► MapLibre. According to the company, the decision to migrate to MapLibre was driven by a desire to modernise and add functionality. At the core of YellowMap’s product offering is SmartMaps, built to address the strict data privacy demands of the European B2B market.
- Jeremy Hsu, of Ars Technica, highlighted a preprint paper by Todd Humphreys and colleagues investigating ‘continental-scale’ GPS interference across Europe.
