  • OSM for Cities is a platform that provides daily updated maps of Brazilian cities using OpenStreetMap data. It features various datasets categorised into areas like cycling, health, education, and more, each showing detailed information with tag coverage percentages. The platform is in early development and aims to expand its coverage and capabilities.

OSM in action

  • [1] A Minecraft builder, AtmosphericBeats, used custom software integrating OpenStreetMap and USGS data to create a 1:1 scale replica of Kansas City, USA, in Minecraft within 36 hours. This innovative project accurately represents buildings, roads, and natural features, demonstrating the potential of combining OSM data with gaming platforms for detailed and realistic virtual recreations.
  • Guess This City is an interactive game in which users click on a blank map to reveal hidden map tiles. Players try to identify the city shown with the fewest clicks.
  • Offensive OSINT discussed the integration of OpenStreetMap into the Open Source Surveillance system, enhancing its geolocation investigation capabilities. It provides a tutorial on using OSM and the Overpass Turbo API to search for various points of interest and objects in the vicinity of specific locations. The update aims to make geolocation easier and more efficient for analysts and researchers by using detailed and up-to-date geospatial data from OSM.
  • Dawn Chorus is a citizen science and art project that invites people around the world to record and share bird songs to document biodiversity, support scientific research, and raise awareness of nature. The Explore page allows users to listen to and explore a variety of bird songs recorded by participants. The interactive map and timeline features allow users to filter recordings by date, location, and species, providing a unique way to experience and study the diversity of bird song across regions and time.
  • TxtDariNAROGONG utilized OpenStreetMap waterway data to visualise the history of Bekasi’s water management system, from the Tarumanegara Kingdom era (circa the 5th century AD), through the Dutch colonial administration, to the recent Indonesian Republic era.


  • Let’s welcome Anton Khorev as an additional maintainer for the OpenStreetMap website code, as confirmed by the recently merged pull request.
  • OSR is a memory-efficient, multi-mode OpenStreetMap router designed for pedestrian, bicycle, and car navigation. It uses compact data structures and memory-mapped files to efficiently import route data, supporting large maps with relatively low memory requirements.
  • Tobias Jordans posted about his efforts to modernise the OSMCha tool by migrating the frontend to a new React-based framework, improving the UI/UX with Tailwind CSS, and tackling technical debt.


  • Bulgent provided > an introduction to using PyOsmium, a Python library for processing OpenStreetMap data. The post covers installation, basic usage, data extraction, geographic calculations, and GeoJSON output. He also contrasts PyOsmium with another library, Pyrosm, highlighting their respective strengths and weaknesses for different OSM data processing tasks.


  • dpschep announced updates to Overpass Ultra, enhancing its customisation features, including loading queries from URLs and Gists, improved configurability for interactive map views, bundled icons for easy integration, and examples demonstrating these features, all aimed at facilitating the creation and sharing of custom Overpass-powered maps.

Did you know …

  • … you can load OSM data onto a Garmin eTrex? Localized to Japanese?
  • Geomob? A series of events and a podcast aimed at geospatial enthusiasts, providing a platform to discuss geoinnovation for both fun and profit.

OSM in the media

  • Grab will provide updated maps of Tengah, a newly developed town in Singapore, to assist residents, drivers, and delivery riders with navigation in the rapidly developing district. This initiative, supported by the OpenStreetMap community, leverages AI technology to improve accessibility and address the needs of service providers in the area.
  • The Youth Innovation Lab presents the BIPAD Portal, a disaster management system in Nepal that integrates OpenStreetMap data to support risk communication and informed decision making.

Other “geo” things

  • Matt Brown introduced two detailed maps of medieval and Tudor London produced by the Historic Towns Trust, highlighting the extensive research and archaeological information used to depict the layout of the city in the 13th and 16th centuries. The maps are available online and in fold-out paper versions.
  • The Linux Foundation Europe has launched the Open Mobile Hub (OMH), a project aimed at simplifying mobile app development through an open-source framework. OMH provides SDKs and tools for seamless integration with mapping services, including OpenStreetMap. Like Overture which wants to address the fragmentation of geographic Open Data, this initiative aims to address fragmentation in mobile development and improve cross-platform user experiences by offering a unified codebase and an extensible plugin architecture.
  • MapFast allows users to quickly create customised, detailed maps by uploading data without needing geometric boundaries or coordinates. It supports CSV files, automatically geocodes geographical information, and offers various customisation options like colours, text, and legends. Users can export maps in PNG or SVG formats and create maps for free with optional subscription plans for advanced features.
  • The latest #geoweirdness thread from OpenCage discusses the geopolitics of football in general and specifically the EURO 2024.
  • The Guardian reported the development of a quantum compass for the London Underground, a subatomic instrument that aims to provide precise location tracking where GPS signals are unavailable. This technology leverages quantum mechanics to enhance navigation and could revolutionize how underground and other GPS-denied environments are navigated, offering greater accuracy and reliability.
  • Komoot released three major improvements in June. New route guidance ensures fewer interruptions. For road cyclists, the route planner now evaluates the road surfaces, guides to road bike-friendly routes, and reduces gravel sections. The new mountain bike router offers insider knowledge about the best trails.
  • OpenStreetMap Japan has announced > the Governor’s Cup Open Data Hackathon 2024, where participants will develop digital services using Tokyo’s open data to solve administrative problems.
