Mapping

• The proposal for railway=balise, fixed transponders placed on or between rails that communicate with trains to provide positioning data and transmit operational information, is open for voting from 27 June 2026 to 10 July 2026.

Mapping campaigns

• After the two strong earthquakes that struck northern Venezuela on Wednesday 24 June 2026, HOT has added collaborative mapping projects to their tasking manager to collect and share critical geospatial data to support emergency response efforts. Ongoing activities also include acquiring pre- and post-earthquake satellite imagery, coordinating crowdsourced remote mapping, and conducting field mapping campaigns to document damaged structures with their locations, photographs, and videos.

Community

• [1] theobcl18 has developed ‘Coupe du Monde 2026 Globe 3D‘, an interactive globe showcasing the locations of all 16 official FIFA World Cup 2026 host stadiums and the 48 participating nations. The globe also provides detailed information on each team and venue, including the latest match results and stadium capacities.
• Pascal Neis has explored if various language models could be helpful for analysing OSM Notes for potentially problematic language.
• Franjo Lukežić continued writing up their next field surveying heuristic. It details how to survey highway=steps. Further, they are working on a cookbook, which contains the existing heuristics, including the one we reported earlier.
• Binyam Dele presented Ambalay Maps at the recent State of the Map Africa 2026 conference.
• Mateusz Konieczny had asked if there are any problems with waterway=stream_end, with a plan to support this tag in the iD presets. That plan has been cancelled based on feedback.
• Christoph Hormann discussed the somewhat peculiar situation of mapping populated places in OpenStreetMap.
• Raquel Dezidério Souto shared, on LinkedIn and Mastodon, the video of her presentation at the State of the Map Africa 2026, titled ‘weeklyOSM-stats: Analysis of the weeklyOSM profile over the last ten years with PostgreSQL’. This presentation aimed to showcase the content profile of weeklyOSM to the event’s audience. The author is delighted that this presentation has finally taken place, as last year’s African event was cancelled for security reasons, following the sudden outbreak of a conflict.
• Geofabrik has added a turn restrictions view to their OSM Inspector, showing both valid and broken turn restrictions.
• Killkenny shared a detailed account of how to collect and verify open sources for mapping small settlements. Using Bukachivtsi and nearby protected natural sites as an example, he showed how to combine data from the cadastre, community websites, Wikimedia Commons, the Wayback Machine, Wikipedia, and other sources, while keeping licensing clearly in mind.
• Silvi715 reported , in her OSM user diary, about the flood prevention mapping activity carried out in Villa Moises, Venado Tuerto, Argentina. In the end a uMap was created.
• 9_tab wrote about the ‘Supermarchés à Genève de A à Z (or rather from A to M)’ in their OSM user diary. The survey around Geneva noted good coverage of supermarkets and inconsistencies in the default brand definitions (NSI) for Switzerland.
• To55 has asked how to map flat addresses in Romania.
• Wikidata Taiwan tooted about the OpenStreetMap x Wikidata Monthly Meetup, which will be held on Monday 13 July, on Chongqing South Road (Taipei, Zhongzheng). You can view the list of events and the WikiProject Taiwan community’s page .

• The State of the Map Working Group has opened the call for posters at SotM 2026, inviting original, openly licensed OSM-related posters in A0 format. Submissions are due by 31 July 2026.

Local chapter news

• Christoph Hormann has decided to let his FOSSGIS membership expire at the end of the year after the association’s virtual general meeting approved an increase in dues.

Events

• Hiroyuki Horin at Sakura Internet, as an infrastructure sponsor of OpenStreetMap Foundation Japan, has published a detailed report ► on the Mappers Summit 2026, held on 1 February 2026 at Sakura Internet’s Bloom Camp. Yui Kitamura, who presented at the event, has shared ► her presentation materials. Smellman reported ► on a tile server implementation, and alt9800 also gave a presentation themed around taking screenshots. Yuiseki reported that they have developed a CLI utility for AI coding agents capable of calling self-hosted Nominatim API, TagInfo API, Overpass API, and Valhalla API.

Education

• IVIDES DATA has hosted ► the fourth session of their 2026 OSM Workshop Series ► with a demonstration on using the KoboToolbox to create and implement web forms with geolocation, which work in any web browser and that are device independent. The training organisers note that those who complete the workshop series within the stipulated period (by 17 July 2026) will be entitled to a free mentoring session on participatory (or collaborative) mapping projects.

OSM research

• HeiGIT showed how openrouteservice can be combined with OpenStreetMap road data and emission model data from the German Federal Agency for Cartography and Geodesy to visualise CO₂ and NO₂ emissions along route segments.

Maps

• The ‘Versatiles Colorful’ layer on OpenStreetMap.org has been replaced with the SVWD03 style developed by Andy Townsend, which is based on the Shortbread open vector tile schema, and offers fast updates.
• Francis Miranda has created an interactive web map, built using OSM, Python and Streamlit, which shows the spatial distribution of the ISMIF index, which represents schools’ vulnerability to flooding events. The index was applied to schools in Rio de Janeiro (Brazil). The code is available on GitHub.
• François Andreaux posted ► , on LinkedIn, about the THT, a web map that shows information on French energy resources and infrastructure. The application lets you click on a plot of land to quickly see the distance to the nearest Réseau de Transport d’Électricité grid and source substations. The web map includes a basemap with OpenStreetMap data.

OSM in action

• MapFuel.ru and GdeBENZ.ru are crowdsourced platforms that collect user reports on fuel availability at gas stations across Russia.

Open Data

• Grant Slater tooted that he has updated the aerial.openstreetmap.org.za website with the latest aerial imagery from the Directorate-General of National Geospatial Information. He has made significant improvements to the website’s performance and the update workflow. The images are now available in iD and JOSM and have a resolution of 25 cm, with excellent positional accuracy.

Software

• The new Trufi App V5 for informal transport in Cochabamba, Bolivia can download OSM data for offline use (because not everyone can afford to be constantly online).
• Korben reported that Yllan has just released OS9Map, an application that displays OpenStreetMap directly on Mac OS 9.
• Pierre Dandumont published ►, on MacGeneration, ‘OS9Map: OpenStreetMap maps for Power Macintosh computers from the last century’, an article dedicated to OS9Map, a Mastodon client for MacOS 9 (not OS X Mavericks 10.9). The article was highlighted on Mastodon.
• Tina and Eugene introduced OsmAnd’s Nautical Map View, a feature designed for planning a trip on the water, practice aquatic sports and find the POIs related to coastal areas. The tool provides depth data, seabed information, beacons, navigation lights, buoys, and fairway details.
• The OSRM Project announced changes to its build environment, upgrading to a more modern platform. Its Linux baseline is now Debian 13 and Ubuntu 26.04 LTS. Minimum compiler support has been raised to Clang 18 and GCC 14. Windows builds now use Visual Studio 2025.
• Steve Vigneau has overhauled trailmaps.app, a web map that combines trail signage and official trail maps with OpenStreetMap data. Rather than maintaining individual maps, the redesigned platform is powered by a map generation system that automatically integrates data from OpenStreetMap and other freely available sources to produce static, cacheable map content that remains accessible even when mobile connectivity is unavailable.

Programming

• Timothée Giraud tooted about his new cheat sheet guide on how to use OpenStreetMap data and related tools with R for geocoding, routing, downloading base maps and datasets.

Releases

• The Freemap Europe tooted about a big update of Freemap.eu for outdoor folks and anyone with map files. You can visit ► the page of the project’s foundation. The files are available on GitHub.

OSM in the media

• clubic reported ► that IGN has inaugurated the cartes.gouv.fr maps website. They also reported about the collaboration by IGN with OSM France and the integration of Panoramax street views (we reported earlier). Gregori Pujol published an article about this launch, highlighting the advantages of using it over Google Maps, on Journal du Geek .

Other “geo” things

• The Real Sociedad Geográfica (Royal Geographical Society of Spain) reported ► on the launch of the new book El Atlas rojo: los mapas soviéticos del estrecho de Gibraltar (The Red Atlas: Soviet Maps of the Strait of Gibraltar) by Agustín T de Villar Iglesias. This work examined the Soviet Union’s vast, secret mapping project during the Cold War, focusing on Andalusia and Gibraltar. In addition to astonishingly precise city maps, the maps contained Cyrillic transcriptions, colour-coding for strategic sites and detailed military-geographical reports (Spravka) on the reverse side. The book and supplementary documentation are available to download free of charge as PDF files from the RSG website.
• clubic reported ► on HyLight, the 12 m, 2 kg zero emission French blimp drone that replaces helicopters to inspect hundred of kilometres of infrastructure per day. The Lidar technology allows the capture of crucial information about infrastructure such as railways and power lines.
