Historic Geographical Information
- Out of date Ordnance Survey maps. Some of these are already available to trace on JOSM/Potlatch etc, however their use for detail is limited. However there does exist many smaller scale (eg 1:500) OS maps that from the 19th Century. At the moment I have not been able to completely verify copyright issues surrounding them, at least not to the extent whereby I would be comfortable using them for OSM, however it does appear they should now be out of copyright. This would make sense as there are far more recent out of copyright OS maps available. The second issue, providing the first is resolved, is getting a hold of them. They can be found on the internet in small amounts, but I would strongly suspect there would be legal issues relating to getting them from these sources.

Historic Geographic Information
Over time, humans have dramatically shaped the surface of the earth. This is particularly true for shorelines and urban areas.
