It was a privilege to introduce the software #internationalization and #localization community to #OpenHistoricalMap (and #OpenStreetMap and @maplibre.org) at #UTW2025. Join us in mapping yesterday already!

Anyone mapping the history of the German Autobahn? We have a particularly fleißig mapper who has set up a project for the daunting task of mapping the historical evolution of die Bundesautobahn & he's off to a great start...

If you’re in #Loouhvull for #NACIS #NACIS2025, look out for these OpenHistoricalMap stickers. Snag one and keep it real! (For the record, we have a scale bar too.)

Love this! Added some metadata to link to an image & to more info. A little hyper-local curation of the hyper-local mapping. Please fix any mistakes made by this former RVA resident (long before the Gun Hole!)

We'd love to help Jacob & others build these extensions, if there's interest. 🙏

And, of course, if anyone would like to keep improving the RVA section of OHM, we'd love to support that, too... just sayin'! 😎

People are probably knocking down your door to add new features, but obviously... we'd love to see an OHM base map that matches the year of the picture, storage of your POIs in OHM, tagging of places in OHM... you name it!

June saw more newly added buildings than in any month since recordkeeping began (for us, anyway). Most of it comes from an import of the Basic Register of Addresses and Buildings that’s getting underway in the Netherlands.

When worlds collide: "Navigating Map Libraries: The Leventhal Map Center and OHM," which will highlight how the #crowdsourced OSM world can work with #GLAM resources, using the resources at @bplmaps.bsky.social as an examplar!

Map labels match your preferred language setting, like the rest of the site. Now you can understand the map even if you don’t speak a language that was common halfway around the world centuries ago. It’s also a lot easier for mappers to know where to improve our language coverage. #l10n #i18n 🧵 3/4

Great thread on in-depth mapping of local history by @sk53onosm.bsky.social over on OSM Town Mastodon:
mapstodon.space/@SK53@en.osm...

🙏 to OSMF for sponsoring OSM Town.

Thanks for the shout-out! 🙏

The data goes back much further than 1825... that's just the default setting that can be adjusted in the UI.
