[1] ‘Cool’ bicycle routing mode – estimated street-level thermal conditions at a resolution of roughly 25 metres | Victor Rotariu | map data © by OpenStreetMap Contributors.
Mapping campaigns
- Uber has proposed, on the OSM Community forum, an organised editing activity to improve pedestrian mapping in 21 countries. Various mappers criticise it due to a lack of details and because Uber has a poor track record in the UK.
Community
- Rphyrin made an Overpass Ultra script for viewing
image=*tags in OpenStreetMap. - MideaFind has used OpenStreetMap data to collect the locations of stores that might sell portable air conditioners.
- Andrea Grandi explained why Book Corners won’t sync contributions back to OpenStreetMap. Pieter Vander Vennet responded in his blog.
Imports
- Oscar Car Rental announced
► that they are planning an organised editing activity to add their 93 missing car rental locations in Germany, along with performing some data maintenance.

OSM research
- Marni Davis documented Atlanta’s immigrant population in the late 19th century, visualising their neighbourhoods on an OpenHistoricalMap basemap.
Maps
- [1] Victor Rotariu and his team are developing a live urban heat map that estimates street-level thermal conditions at a resolution of roughly 25 metres. This data will power a new ‘Cool’ routing mode. Rather than selecting only the fastest or shortest cycling route, Cool mode will identify the route with the lowest estimated heat exposure. The goal is simple: help cyclists avoid the hottest streets, enjoy a more comfortable ride, and arrive at their destination with less sweat on hot summer days.
OSM in action
- A 23-year-old student developer from South Korea has created a navigation app for finding shade covered areas, which has shot to the top of the App Store’s navigation apps. The app uses OpenStreetMap data to plot routes.
Software
- HeiGIT presented their latest update on the roadmap toward the new ohsome API 2.0, outlining the next steps in the evolution of the ohsome platform for analysing OpenStreetMap data. The update introduced planned developments, improvements, and future directions aimed at creating a more flexible, efficient, and sustainable API for OSM history data analytics.
Releases
- The CoMaps team published release 2026.07.16, which is now available via Codeberg, F-Droid, Google Play, and the iOS AppStore. This version adds a preview of turn-by-turn directions when creating a route, adds lane guidance and improved next turn descriptions for iOS/CarPlay, per-transport-mode routing options, support for more OSM tags, and many further bug fixes and improvements.
- Organic Maps July 2026 has been released, bringing a collection of bug fixes and general improvements.
- A note for mappers resolving notes: Organic Maps version 2026.07.15 has fixed a long-standing issue, where notes left inside large forest polygons and road lines would always move to the centre of the object. Notes are now added at the user’s click location.
- Tina announced that OsmAnd Astronomy, currently available in the OsmAnd Android 5.4 beta (on paid plans Maps+ and OsmAnd Pro), now includes tools for exploring solar and lunar events. Users can move through a timeline to preview upcoming astronomical events, check eclipse visibility from any location on Earth, and watch exactly how each solar or lunar eclipse will unfold before it actually occurs.
- HeiGIT reported the release of Ohsome-Planet version of 1.3.1, codename ‘Baarle-Hertog‘. This tool is designed to facilitate the transformation of raw OpenStreetMap history data into the geoParquet format, making it more accessible for spatial data analysis.

OSM in the media
- BRUZZ, a local newspaper in Brussels, commented ► on the rise in recent years of private swimming pools in residential neighbourhoods. They praised OSM volunteers for having mapped them and showed maps with their locations.
- Heise’s c’t Open Source Spotlight newsletter reported ► on CoMaps and interviewed OSM community member Bastian Greshake Tzovaras about CoMaps, OSM and free software in general.
►Other “geo” things
- Google had integrated its AI image generator ‘Nano Banana 2’ into Google Earth. They removed it two days later after people started abusing it, as the BBC reported.
- The Times of India explained how Polynesian navigators crossed the Pacific Ocean by reading the stars, ocean swells, winds, birds, and clouds to find their way.
- In response to the recent news about Moroccan migrants crossing into the Spanish enclave of Ceuta, OpenCage reshared their previously published geo-trivia posts about Spain and Morocco.
