In September, the #OpenHistoricalMap community added 78,430 dated elements, 10,580 buildings, and 20,439¼ railroad miles. The average age of a dated element fell by 21 months, and the average year shifted 17 months later. All this with the help of 30 new mappers – welcome!

Yes, your georeferenced maps would be useful. You’d use them as reference layers, digitizing the depicted features. The only challenge is that a pre-digital map only represents a snapshot in time, so you’d need to qualify the dates with some uncertainty: wiki.openstreetmap.org/wiki/OpenHis...

Help @maprva.org develop an historical street view of Richmond, VA by georeferencing old photographs! The catalog is actively growing and currently includes 1900 photos from the Library of Virginia and the @thevalentinerva.bsky.social

But, before we get to all of our self-interested stuff, HUGE KUDOS to Jacob & the @maprva.org team. You guys should take a huge bow and deserve tremendous applause – this is an amazing amazing tool!!!!

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!

Love, love, *LOVE* this.

There's a fair amount of old RVA mapped already on OHM, and OHM has support for pictures, too, but this is a fantastic and easy to use integration. Can other cities might host their own versions?

Question for the medieval crowd: does anyone know of a good published map of Europe in 1066? (yes, I have googled)

Clues about history are never far and neither is @vespucci.io. With its new support for editing OHM, you can jot down what you learn from a #cornerstone #plaque #SidewalkStamp right on the spot, before the dates get jumbled around in your head.

#SanJose is looking a little busier in #OpenHistoricalMap. Comprehensive historical coverage of #TrafficLights (courtesy of the city) makes it easier to tell where the major streets ran.

www.openhistoricalmap.org#map=15/37.33...

wiki.openstreetmap.org/wiki/OpenHis...

1960 and today:

In 1960, there were only a handful of traffic lights downtown. The city limits were starting to expand to the east. A railway line still ran north and south along the east side.

Today, series of traffic lights indicate where major arterial streets run, such as Story and King roads. The Guadalupe and Sinclair freeways cut across the city, and a large interchange with the Bayshore Freeway dominates the right side of this map.

Whether you go big or go small, you can’t map it all. But you can lay a foundation to grow and guide a new historical mapping community. Minh Nguyễn mixes as many metaphors as possible to show us how:
