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.
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!

@ohm No!!! I always got annoyed mapping OSM because I couldn't save the history of places. Now I have such a place.

@ShionAmasato Love this example of finding information on old buildings and using OpenHistoricalMap as a place to store that data!

Two new themes have dropped:
For all the #train enthusiasts out there: https://mapcomplete.org/historic_rolling_stock shows a map of historical locomotives and other rolling stock that are permanently placed somewhere - e.g. monuments, in a museum or just abandoned.
https://mapcomplete.org/historic_aircraft is a similar map showing #aircraft , interlinking with #wikidata for the models.
Beware: they are dangerous: they are quite addictive to get everything right...
“Historians use data science to mine the past,” in PNAS, provides an overview of how historians are using computational methods to analyze digitized sources.
These methods become more essential as historians start working with more recent born digital records at scale. https://www.pnas.org/doi/10.1073/pnas.2508428122
@grimalkina Next month’s #StateOfTheMapUS will have a healthy mix of the human and tech sides, both grassroots and institutional, that would be relevant to those in or adjacent to #GIScience. Our friends at @OpenStreetMapUS offer discounts for academic affiliation, and they just started raising funds to hopefully offer scholarships for affected government employees too. https://en.osm.town/@OpenStreetMapUS/114457256592594448

I am tickled to see this bit of web trivia listed in @TheSeattleTimes “Today in History”. I represented Boeing to the #WorldWideWebConsortium (#W3C) for years. That international Web standards org was made possible because @timbl and @CERN generously gave the initial web code to the world for free — apparently on April 30, 1993. Many of my friends here are from that connection. I am deeply grateful for that experience. And of course that we have the Web!
