- Rphyrin has used OpenStreetMap data to map the extent and impact of Jakarta’s torrential rain on 12 January, which diverted 16 flights from Soekarno-Hatta Airport.
- Matt Whilden has built a new game titled ‘The OpenStreetMap Tag Showdown’, a turn-based challenge built around OpenStreetMap tagging knowledge. The game invites players to take turns adding tags to construct a query, with the risk that an invalid or non-existent tag combination can be challenged by the opposing player.
Local chapter news
- The French community recently realised that the max weight restrictions in France actually are about the max weight rating, and not about actual weight as in many other countries. The historic usage of
maxweight=*for such weight restrictions in France is therefore invalid. It was decided to progressively migrate tomaxweightrating=*in France:- in February 2026, the OSM objects tagged with
maxweight=*will be dual-tagged withmaxweightrating=*, with anote=*explaining thatmaxweight=*is deprecated for France, must no longer be used, and must be replaced withmaxweightrating=*; - in July 2026, all the
maxweight=*keys of France will be deleted with the aforementionednote=*. - Contributors and software currently using
maxweight=*in France are asked to prepare for this migration.
- in February 2026, the OSM objects tagged with

Maps
- Martin Ždila, of Freemap Slovakia, has presented Freemap.sk, a project that began as a community initiative to deliver a high-quality outdoor map for hiking and cycling in Slovakia, built entirely on OpenStreetMap data. Over time, it has developed into a full-featured web mapping application and has since expanded to cover most of Europe with an outdoor-orientated cartographic style.
OSM in action
- [1] In the podcast Stories from History ►, produced by the two historians Richard Hemmer and Daniel Meßner, one of them tells the other a ‘story from history’ that was previously unknown to the other. Many followers write postcards to the duo from all over the world. Richard Hemmer has recently published ► these postcards on a website using OSM as a basemap.
- In his new weekly column, mobileGEO explored ► the critical challenges facing OpenStreetMap, from opaque governance structures in software maintenance, to accessibility mapping and micro-mapping efforts in Vienna, highlighting resilience, inclusion, and long-term infrastructure sustainability.
- Whoosh, one of the largest scooter and bike sharing services in Russia, has started using OpenStreetMap maps instead of the commercial Yandex.Maps in its mobile apps.
- Igor Gromov and his friends have started creating the memmap, a map for meme videos. So far, the map is limited to the city of Saint Petersburg, but there are plans to add support for new cities. An OpenStreetMap-based map is used as the basemap.
►Software
- The CoMaps project shared their plans for 2026, which focus on the long-term sustainability of the project and their apps.

Note:
If you like to see your event here, please put it into the OSM calendar. Only data which is there, will appear in weeklyOSM.
This weeklyOSM was produced by MarcoR, Raquel Dezidério Souto, Strubbl, Andrew Davidson, TrickyFoxy, barefootstache, derFred, mcliquid.
We welcome link suggestions for the next issue via this form and look forward to your contributions.
I think all links should open in a new window (target blank),
that way we know OSM Weekly will still be there when we are finished reading one of those links,
and we needn’t remember to hit the back button.
I agree with that, but did you know that middle-clicking or left-clicking with CTRL pressed opens a link in a new tab?
Yes. However it’s a rare case when the user actually wants to replace the whole article they’re reading with just the new page, except if it’s the very last link. Therefore I think the majority case should be taken into account, where there should be the target blank type link.
