OpenHistoricalMap collaboratively stores and displays map data throughout the history of the world.
OpenHistoricalMap is built by a community of mappers and historians that contribute and maintain data about the history of the world.
Since OSM is only concerned about the current state of the world, it does not support historical data: e.g., there is no trace on our favorite collective maps of, e.g., traces of train tracks around the world since the automobile industry
made them obsolete forced them to obsolescence. If you’re not aware of how industries and market influence technological reality – rather than technical excellence, as the myth of Progress loudly tells us – then you have no chance to ever imagine how things were or could have been different.
This site might help do just that, and that’s pretty much aligned with IN COMMON.
