Mapping campaigns

• The UseOSM community has announced Map<>kathon 2026, an online data sprint that shifts the focus from creating OpenStreetMap data to demonstrating its use in real-world applications.

Community

• [1] Jonas has written a guide to help newcomers get started with indoor mapping in OpenStreetMap.
• Arjunaraoc presented a report on the contributions made by new OSM editors in the Indian state of Andhra Pradesh during the first quarter of 2026.
• Candid Dauth has developed a set of overlay tiles highlighting toll roads, roads where cycling is prohibited, and roads with cobblestone surfaces. The overlays are hosted on tiles.facilmap.org and are also available as map styles in FacilMap.
• Frédéric Rodrigo posted an entry, on their OSM User Diary, about major changes introduced by version 0.5 of Clearance, a free software tool for controlling the quality of OpenStreetMap replication diffs (we reported earlier). It tracks thematic and territorial edits to OSM and keeps replication extracts (extracts, diffs, and a local Overpass API) up to date. The source code is available on GitHub.
• M Fuhrmann reported that the OpenStreetMap community in the German city of Fulda, in cooperation with Magrathea Laboratories e.V. – Chaos Computer Club Fulda, has launched a Panoramax instance.
• Rodolphe Bussers, a Belgian hiker, has published mongr20.com, a bilingual (French/English) website for those planning to walk the GR20 (Corsica) trail, built entirely on OSM: the route is compiled from OSM data (182.4 km), freely downloadable as ODbL GPX tracks of all 16 official stages, an interactive stage planner, and derived analyses (per-stage effort scores in both walking directions).
• Stéphane Branquart reported ► that Teritorio recently conducted an OpenStreetMap training session for the Limouxin Tourist Office team, helping them improve local geospatial information for both residents and visitors.

OpenStreetMap Foundation

• The Proceedings of OSM Science 2025 is now available on Zenodo.org. The volume was organised by Marco Minghini and others.

Education

• Anne-Karoline Distel shared a video on mapping wheelchair accessibility in OpenStreetMap, based on a presentation delivered at the Irish Wheelchair Association in Kilkenny (Ireland).

OSM research

• DoudouOSM highlighted that pavements, ramps, kerb ramps, stairs, pedestrian crossings, and streets are the key elements of accessibility mapping in OpenStreetMap, while properties such as length, slope, width, and surface play a crucial role in determining wheelchair mobility in urban environments.

Humanitarian OSM

• Akash Wadhwani has created an interactive visual essay exploring OpenStreetMap editing activity following the February 2023 Türkiye–Syria earthquake.

Maps

• The National Center for Monitoring and Alerts for Natural Disasters of Brazil has launched ► an interactive web map for tracking the severity of drought in Brazilian municipalities, which uses OpenStreetMap as a base layer.
• Open Water Software LLC has developed Seascape, a web-based global seafloor bathymetry dataset delivered as map tiles. Built from a mosaic of global and regional sources, it provides raster digital elevation model tiles for depth shading and hill shading, along with vector contour tiles.
• Andrea Grandi developed Book Corners, a map designed to help users discover and share nearby free little libraries. The application retrieves location data via the Overpass API, which is then processed through its data pipeline.
• Tykayn shared a map of France displaying OpenStreetMap speed limit (maxspeed) data, created using maxspeed-map, while encouraging users to contribute to Panoramax, noting that submitted photos help categorise speed limits on road segments.
• Stevefaeembra shared a map of lighthouses across Europe, created using OpenStreetMap data.
• ‘Third Places’ is a web map of New York City’s community gatherings, based on OpenStreetMap, from which were extracted all place nodes in NYC matching the ‘third place’ categories such as coffee shops, bars, libraries, parks, community centres, places of worship, bookshops, laundrettes, and dozens of other types. The term ‘third place’ was coined by sociologist Ray Oldenburg in 1989 to describe the informal gathering spaces that anchor community life, distinct from home (the first place) and work (the second place).

OSM in action

• Julian Lindner, a student of urban planning, has launched Plantaube. This online tool enables urban planners and architects to create attractive city and site plans using OSM data. The tool is fully customisable and can be used free of charge in a web browser.
• Max Kreisler developed Rauchfrei Berlin, a community-driven map of smoke-free bars and venues across Berlin. The listings are crowd-sourced, allowing users to contribute by suggesting venues that are missing from the map.
• Tempo na Rota provides weather conditions and forecasts along travel routes across Brazil, using OpenStreetMap data as its basemap.

Open Data

• Panoramax showcased several region-specific instances that are currently accessible online.
• In a blog post, Stadia Maps explained that proprietary map services use outdated data collected during embargo periods, which leads to persistent errors. Instead, the company relies on open and proprietary data streams, ‘Fix-it’ links for reporting errors embedded directly within the API, and updates at least once a month. In addition, Stadia Maps is collaborating on an open-source set of address templates to reflect country-specific address conventions.

Software

• Christian Quest reported that the Panoramax instance operated by @ignfrance@social.numerique.gouv.fr will be migrated during the Bastille Day long weekend (around the 14 July public holiday in France). During the migration, the service will be temporarily switched to read-only mode. Users will be unable to upload new photos for a few hours, although all existing photos will remain accessible for viewing throughout the maintenance period.
• fghj753 developed a working prototype that allows users to select a packaging container’s colour, instead of manually listing 15 to 30 recycling:* tags, with the editor automatically applying the appropriate tags.
• Stadia Maps explained that Google deprecated the ‘Heatmap Layer’ in its Maps JavaScript API in May 2025 and removed it entirely one year later, leaving google.maps.visualization.HeatmapLayer users without a migration path. The company described how a former Google Maps customer switched to MapLibre GL JS with Stadia Maps tiles, gaining a native, zoom-responsive heatmap layer not tied to any single vendor. Stadia Maps argued the episode shows the risk of building on closed platforms, where features can disappear without warning.
• Frank März has developed Hydrant Hunter v1.5.3, a web-based tool that allows users to photograph fire hydrants and upload the images, along with their geographic coordinates.
• Ian Dees has made a web-based tool that generates before-and-after images of areas in OpenStreetMap, allowing users to visualise mapping progress over time.
• Project OSRM announced that OSRM now offers official Python bindings, allowing users to access routing, table, match, trip, and nearest functionalities directly from Python.
• Andy Townsend tooted that switch2osm.org has been updated to cover tile servers using both ‘flex’ as well as the older ‘pgsql’ outputs.
• mschwehl has developed TourGaze, a local-first ride viewer that enables users to import, browse, tag, replay, compare, and analyse recorded tours data. The application converts FIT, GPX, TCX, and KMZ files into a searchable, taggable ride library, featuring cinematic map replays, advanced ride analytics, and a ghost-chase comparison mode.
• vgeorge has built ‘OSM for Cities’? This is a platform that makes OpenStreetMap-based city data more accessible by distributing open datasets for urban areas worldwide. Users can search for any city and explore data within its administrative boundaries without requiring technical expertise or data preparation. The platform supports a range of ready-made map templates, including bus stops, schools, and trees, allowing users to visualise selected datasets with a single search.

Programming

• Paco Albacete Chicano shared a progress update on his Google Summer of Code project, which focuses on prototyping a medial axis implementation for area routing in Valhalla. The medial axis, also known as a topological skeleton, is a geometric representation used to compute efficient navigation paths through open spaces.
• Nicolas Lambert has developed Geoviz, a JavaScript library for designing thematic maps.

Releases

• Organic Maps has released its June 2026 update, which added navigation for all types of public transport, alternative routes, and the ability to specify a custom map background (for example, satellite or terrain)
• Pablo Brasero recapped the recent changes made to the OpenStreetMap website, including a switch of the Shortbread slippy map style from Versatiles Colorful to SVWD03 (we reported earlier) and an update of iD to version 2.41. The recap also covered performance work, such as re-enabling JavaScript minimisation and reducing the amount of script sent to visitors, and an upcoming feature that lets moderators define time-limited zones blocking anonymous notes.

Other “geo” things

• Staatsanzeiger reported ► that the government of Baden-Württemberg, one of Germany’s 16 federal states, has announced measures to strengthen its defence capabilities and resilience. Interior Minister Manuel Hagel said the initiatives include protecting sensitive locations in online mapping services. His ministry will instruct all state departments to ensure that sensitive information is obscured or pixelated on map platforms.
• 1Spatial has integrated ► Panoramax images directly into their Système d’Information Routier (router information system).
• QGIS has announced the beginning of a new development phase leading to the next long-term release of QGIS (4.2.4), which builds on the foundation of the Major Version 4.0 update that transitioned the core of QGIS onto the modern Qt6 framework. This release bundles loads of performance optimisations and newly introduced features, including multiple enhancements to 3D capabilities and processing tools. The 4.2.4 release is scheduled for the end of October.
