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.
