And that’s just a couple of the many things we’ve been up to lately. Keep the feedback coming and we’ll see you on the map!

For mappers, it’s a lot easier to see opportunities to improve our language coverage.

Do you already contribute to @openstreetmap? You can start contributing to OpenHistoricalMap too in just a few clicks, without having to juggle yet another password for yet another mapping site. Once you have a taste of OSM #SingleSignOn via #OAuth2, you’ll never look back.

Hard to believe it’s already been three months since we deployed our big round of performance improvements and more. Since then, the development team has continued to push out periodic improvements to the site, some more noticeable than others. You just haven’t heard about it from me because I’ve been a little busy. I’ve started writing up similar announcements for OpenStreetMap too. Think of those announcements as a preview of things to come in OpenHistoricalMap the next time we update our code...

We’ve never seen such a sharp uptick in new railroad coverage like we’ve experienced in May, particularly in present-day Argentina, Finland, and Mexico.
OpenHistoricalMapJun 2

In the past month, the #OpenHistoricalMap community added 49,939 dated elements, 5,965 buildings, and 293,247¼ railroad miles. The average age of a dated element fell by 14 months, and the average year shifted over 6 months later. All this with the help of 31 new contributors – welcome!
