About us

• [1] Please don’t be alarmed if you’ve seen your browser being tested – even if only briefly.Our website was under enormous strain from AI scrapers. To defend against these scrapers, we’ve installed Anubis.

Community

• Within the framework of the UN Mappers Chapters Initiative, Modo Levo Engelbert Steve had the honour, as Ambassador, to lead the CityMapper Externship project, training young Africans to solve local challenges and improve OpenStreetMap. He told of the results in his OSM User Diary, emphasising that this initiative would certainly not occur without the invaluable help of its partners: IVIDES DATA, GeOsm Family, Geospatial Girls & Kids, Humanitarian OpenStreetMap Team, and TomTom. SeverinGeo tooted that this resulted from a story that began a few years ago.
• Paul Norman reported that the reversion of erroneous mass-imported data in OpenStreetMap has led to replication delays affecting multiple services.
• StephanT has extracted the data from the ‘Treaty between the Federal Republic of Germany and the Czech Republic on the Common State Border’; both the Federal Republic of Germany version and the Czech Republic version . They have compared them, and thoroughly documented the resulting inconsistencies, discrepancies, and errors on the OSM Community forum.

OpenStreetMap Foundation

• Members of the OpenStreetMap Foundation Board of Directors met at TomTom’s Madrid office on 6 and 7 June for a two-day working session focused on priorities and action items to be addressed over the next 12 months.

Events

• The State of the Map 2026 programme is now online. The programme starts on Friday 28 August, with the opening session, followed by the special keynote ‘State of Panoramax’ to be given by Adrien Pavie and Christian Quest. You can read more on Mastodon.
• The Canadian Open Data Summit will take place on 14, 15, and 16 October in Windsor, Ontario. The call for proposals is currently open, with groups and individuals invited to submit workshops, panels, lightning talks, or presentations in English or French.

Education

• IVIDES DATA hosted the third session of its 2026 OSM Workshop Series, which focused on QGIS plugins for OSM data. The workshop featured practical case studies covering accessibility, urban tree cover, and geo-locating buildings near areas susceptible to landslide disasters.

Maps

• Å»aneta Piasecka posted, on LinkedIn, about her interactive map, which she created in order to answer some questions related to the 2026 FIFA World Cup: Where exactly are these stadiums located and how accessible are they? Are they in the city centres or out in the suburbs?

OSM in action

• velowire.com publishes the routes of several cycling races precisely drawn in OpenStreetMap, along with the facility to download them as .KML files and to view them using Google Earth, iD, Gnome Maps, or any other software with support to read KML files.
• Power Pro, a hotel management software platform, is utilising OpenStreetMap data to help track the locations of support tickets submitted by hotel managers, enabling more efficient monitoring and coordination of maintenance and service requests.

Software

• GeoServer version 3.0 has been released â–º, promoting a major modernisation, according to Aurelio Morales, author of the post on the Mapping GIS blog.
• At the recent Chaos Computer Club DO_BYTE 2026 â–º conference, Marc presented the Panoramax project, sharing insights from day-to-day operation of a Panoramax instance and offering practical guidance on creating 360-degree imagery.
• Ian Wagner wrote, on Stadia Maps’ blog, about how building a location-aware application often starts with a simple goal: helping users find where they need to go. He looked at specific gaps in the current geocoding landscape and how Stadia Maps built a more reliable path forward.

Did you know that …

• … the OpenStreetMap Foundation Board has given itself a set of rules to govern how the Board does its work?
• … the OpenStreetBrowser, under the ‘Culture – Media/Wikidata’ category of the ‘OpenStreetMap Quality Control’ section, now checks for references for subject, artist, architect and name etymology (when appropriate)? You can read more in the article written by plepe.

Other “geo” things

• On Saturday 20 June Yves Lacoste, one of the most prominent scientists in geopolitics and critical geography, died â–º. He coined famous and controversial expressions, such as the one that inspired his 1976 book La Géographie ça sert d’abord à faire la guerre (Geography serves, primarily, to make war). As the founder of the journal Hérodote â–º, he devoted himself for decades to demonstrating that there is no neutrality in geopolitical relations, highlighting the inequalities in the balance of power among states.
• Space.com reported that an experimental satellite has mapped the extent of GNSS jamming across Europe and the Middle East from space.
• Esri España has opened â–º submissions for the ‘Maps in Action’ GIS Competition 2026, with entries due by 21 September. The winning project will be unveiled during the Esri Spain Conference 2026, scheduled to take place from 30 September to 1 October.
• Version 2.026.23 of KoboToolbox has been released, featuring a series of fixes and small updates. This marks (as previously announced) the permanent removal of the version 1 (v1) API. So, integrations using v1 endpoints are no longer working. You can consult a quick guide for migrating from v1 to v2 endpoints in actual applications.
• Reuters has launched their ‘Reuters Climate Monitor’, an interactive web dashboard featuring a globe-based visualisation that shows how current temperatures compare with historical averages around the world.
• Rakeda has developed ‘Metiq‘, a real-time 3D globe platform that allows you to visualise more than 100 public datasets.
• u/Evilgrandma03 posted on reddit about a language map of Switzerland, excluding uninhabited mountains, which was created with the official map of the Swiss Federal Statistics Office (FSO) overlaid on top of the mountain map.
• Net Zero Frontiers reported that Greenpeace researcher Nibedita Saha used a thermal camera to measure temperature variations across several urban locations, finding that surfaces shaded by trees can be up to 20°C cooler than those exposed to direct sunlight, highlighting the significant role of urban greenery in mitigating the urban heat island effect.
• secara.teratur has analysed several of the volunteer geographic information platforms that are popular in Indonesia, such as OpenStreetMap, Local Guides, and Foursquare.
