Thank you to all the donors who have supported OpenHistoricalMap's fundraiser. We are more than 50% away from the timely goal of $2,026.
Donate: https://openstreetmap.app.neoncrm.com/forms/ohm-2026
Help us get there! Your investment will go directly toward enhancing OHM's dependability and usability.

Oops! #OpenHistoricalMap was supposed to be a map of history, but then the linguists found us and turned us into an accidental map of the history of writing. @mxn shows how we and @maplibre are bringing #HGIS to more language traditions all over the world:

Ran a fun Palestine Open Maps mapathon yesterday with Yara Sa'di-Ibraheem. She's researching communications infrastructure in Palestine during the British colonial era, so we extracted the telecom infrastructure in the historical maps using the Tasking Manager, based on Yara's paper: https://doi.org/10.1016/j.polgeo.2024.103242
We got a lot of work done! Blue squares are the ones that have been worked on. There's a long way to go, but good progress.

En 2013, un groupe de personnes (@ohm) lança "la carte la plus universelle, détaillée et périmée du monde" : Open Historical Map https://www.openhistoricalmap.org
12 ans plus tard, je l'ai découverte :-) via son intégration au logiciel de généalogie libre #gramps

It is such a nice feeling when you find that last source that allows you to add something to OpenHistoricalMap after scouring old newspapers. I've been adding old theaters in my home town and have been making nice progress.

The #VectorMaps branch of @openrailwaymap has started double-tracking #OpenStreetMap and #OpenHistoricalMap data. Finally – appreciate #AbandonedRailways in the proper setting!

Our #OSMCha instance makes it easy to inspect large changesets for subtle changes. Sometimes, those changes look very wrong, but only because modern aerial imagery doesn’t line up with the historical features being mapped.
Now you can visualize changesets against existing #OpenHistoricalMap coverage to see how it all fits into the map we’re building. Click the 🗺️ button to set the basemap back to #Mapbox or #BingMaps imagery like before.

@openrailwaymap Thanks for https://OpenRailwayMap.org!
ORM renders abandoned and razed rails. Many OSM communities understandably frown upon adding features that aren't visible on the field any more, which railway=razed is.
Would it be an idea to stop rendering railway=abandoned and railway=razed from #OpenStreetMap and instead pull in historical railways from #OpenHistoricalMap? #OpenRailwayMap could even grow a dedicated "history" layer.
I think this would be beneficial for ORM, OHM and OSM!

Oh – steer clear of these ghostly cars! 👻 This time of year, they might lure you into pulling an all-nighter for #OpenStreetMap and #OpenHistoricalMap. You might even stumble upon a hidden message among the road markings and traffic signs plainly visible in street-level imagery and #OpenAerialMap drone footage. Wouldn’t that be horrifying?
Join us tomorrow at twilight to share tips and #tricks for #micromapping. https://www.meetup.com/open-source-san-jose/events/296071990
