Mapping
- Two proposals are waiting for your comments:
- The
cable_landing_station=* proposal to map landing points of submarine cables.
- The
highway=safari_service_road proposal to describe specific service roads in safari parks.
- The proposal
flashing_lights=* is still open for voting. The proposal intends to indicate the precise design of flashing lights.
Mapping campaigns
- Following the Morshansk online map party
►
in 2025, the Russian community is organising another online map party
►
from 29 March to 11 April. The community will be working to eliminate one of the last major blank spots on the map: the Kunyinsky District of the Pskov Region. This year’s innovation is a new tool
for coordinating zones during collaborative mapping, written specifically for this event. We invite everyone to participate, both beginners and experienced participants!
Community
- In the sharply worded, normatively charged, and at times speculative opinion essay ‘The City in the Data Lab’, mobileGEO offered
an activist analysis of OpenStreetMap as an increasingly central digital infrastructure used for routing, research, and humanitarian missions, among other things. At the same time, they addressed the dependence on a small number of volunteers in core areas, such as server operations and software, as well as issues of governance and data equity.
- A forum post discussed introducing new tools for discussions on the OSM Wiki, including the MediaWiki DiscussionTools extension already used on Wikimedia projects. The aim is to provide more structured commenting and improve participation, with implementation currently being discussed as an Operations Working Group issue.
- Christian Quest announced the creation of the Panoramax Foundation to establish an open source platform for georeferenced street level imagery. The foundation is to be launched as a non-profit organisation and will be supported by partners such as the INRIA Foundation and IGN France. Its aim is to promote decentralised server structures, establish a global meta-catalogue, and strengthen cooperation between authorities, companies and NGOs. Members can actively shape technical development and governance (via the GeoCommuns Forum).
- In a blog post by the ‘OSM Verkehrswende’ initiative, Tobias Jordans explained
►
that Panoramax requires additional infrastructure and coordination. The goal is to further expand this open-source alternative to commercial services and promote its use for mapping, traffic planning, and data analysis.
- Marina Petkova wrote
►
about the release of the guide OpenStreetMap et territoires (OpenStreetMap and territories), produced by the Fédération des pros d’OSM. The video record of the session can be watched
online. There is also a publication
about the ODbL titled Tout savoir sur la license ODbL.
OpenStreetMap Foundation
- The OpenStreetMap Foundation Board has approved a new contractor to revamp the GNSS traces feature on the OpenStreetMap website, aimed at renewing the infrastructure for GNSS traces and complying with privacy regulations. The payment comes from the Sovereign Tech Fund, and the rate has been discussed with the Personnel Committee and Core Software Development Facilitator.
Local chapter news
- OpenStreetMap US announced the release of the Pedestrian Working Group Schema 1.0, defining a tiered tagging system for mapping pedestrian infrastructure. The schema provides detailed guidelines for features such as pavements, crossings, and kerbs, aiming to support use cases from basic navigation to accessibility-focused routing applications.
Events
- The FOSSGIS 2026 presentations are available
online.
Maps
- Mlvln described his workflow for a Berlin streetscape map using
area=highway data. He combined QGIS with the Overpass API, but switched to Geofabrik’s OSM extracts after his computer could no longer process the raw data. Using Osmose and Python scripts, he filtered tags such as surface=asphalt or amenity=waste_basket and converted HStore fields for visualisation. His goal: a zoom level-dependent tile map – but hosting and regular updates remain open problems.
- Henri97 introduced the portal-streuobst.de
►
, a new map designed to support the mapping and analysis of orchard meadows based on OpenStreetMap data. The project aims to help validate NABU’s estimate of around 250,000 hectares and encourages community feedback and contributions.
OSM in action
- The Geo3D Library is a central hub for publicly available online 3D geological models. It is maintained by the Polish Geological Institute and the National Fund for Environmental Protection and Water Management. It includes OpenStreetMap, Carto Light and OpenTopoMap as basemaps.
Open Data
- Qi Zhou and others have published an open dataset of inland docks along the Yangtze River based on OpenStreetMap data and high-resolution satellite imagery. Using YOLO models they detected 3,562 docks with high accuracy and provided the results as bounding boxes and polygon geometries for further analysis.
Software
- A new security report highlighted CVE‑2026‑2580, affecting the WP Maps – Store Locator WordPress plugin by Flipper Code, which is used with OpenStreetMap, Google Maps, and Mapbox. The issue allows outsiders to access sensitive website data on sites running plugin versions up to 4.9.1, so site owners and developers are encouraged to update and review their map setups promptly.
- [1] Héctor Satrústegui explained how to optimise OpenStreetMap tiles for eInk devices such as Meshtastic or Meshcore. The approach uses Maperitive to generate tiles and a Python script to convert them into greyscale or black-and-white formats, improving performance and usability on low-resource hardware.
- The new iD tagging schema release v6.15.0 includes
sidewalk= as a road property, multiple new icons (building under construction, covered reservoir, honey shop and more), animal=horse_walker was added, shop=butcher and other recovered their fields, making it easier to find many objects, and the deprecation of landuse=basin was stopped.
Programming
- d0min0 introduced Drakkar.one, an embeddable map widget that works without API keys, cookies, or Google services. It uses OpenStreetMap data and serves vector tiles as PMTiles via Cloudflare infrastructure, offering a low-cost and privacy-focused alternative to Google Maps embeds.
- Pascal Neis outlined a custom processing pipeline to analyse the full OpenStreetMap planet and generate vector tiles. The approach considers historical object versions and prepares the data for efficient visualisation and analysis workflows.
- The Infra Plan team released on GitHub
bim-tile-overlay, a JavaScript library that renders map tiles such as aerial imagery or OpenStreetMap beneath 3D BIM models in Autodesk Viewer. It handles coordinate transformations from local model space to WGS84, computes visible tiles in real time, and projects them in sync with the camera view.
- tristanmk introduced Simple Routing, a low-cost routing API service built on OSRM and VROOM, targeting small projects and developers. The platform aims to bridge the gap between limited free APIs and expensive commercial services by providing shared infrastructure with transparent pricing.
- zorun presented a project implementing an OsmAnd plugin that calculates pedestrian routes based on shade coverage to improve comfort in sunny conditions. The plugin relies on custom-generated shade data, and currently works only for Nantes. The diary entry highlighted usability and integration challenges identified during testing.
Releases
- In a blog post the GraphHopper team introduced improvements made to elevation data handling, enabling more accurate slope and distance calculations. These enhancements particularly benefit use cases such as cycling and hiking routing, where precise elevation profiles are essential.
- The developers of Vespucci released version 22 beta, introducing numerous bug fixes and stability improvements, including handling of Overpass queries, uploads, and UI behaviour. The update also added features such as enhanced tag filtering, image upload support, and improvements to changeset tagging.
- The iD team released version 2.39.0, introducing improvements such as expanded recently used presets, clearer validation messages, and enhanced geometry editing. This release also included multiple bug fixes, updates for street-level imagery, and technical modernisations in the codebase.
Other “geo” things
- Apple has announced plans to introduce advertising in Apple Maps, allowing businesses to pay for promoted placements in search results and recommendations. Advertisements will be clearly labelled and, according to Apple, not linked to personal user data, as part of a broader expansion of its advertising business.
- In their paper ‘Bench marks of change’, Catherine Porter, Margaret O’Sullivan and Elizabeth Gabbett analysed the survival and loss of Ordnance Survey benchmarks in County Limerick, Ireland. Using GIS, historical cartography, and participatory methods, the study finds that over 90% of these historic survey marks are no longer visible and interprets their disappearance as an indicator of broader landscape and environmental change.
- Chronotrains is a Web map which shows how far you can travel by train, from a specific city, for example Berlin. You can select a European city and specify the travel time.
- The EO Glossary of Terms and Definitions serves as a reference for everyone involved in Earth Observation. It covers a wide range of terms, concepts, and definitions relevant to EO disciplines including remote sensing, satellite imagery, geospatial analysis, calibration and validation, climate adaptation, and more. It includes more than 30 recognised databases and you can see a graph with the hierarchy involving the terms.
- The Guardian published a video about how Google Maps search algorithms shape the types of restaurants people find and frequent.
