Digitizing and Geocoding Old Maps?
alobar72 writes "I have quite a few old maps (several hundreds; 100+ years old, some are already damaged – so time is not on my side). What I want to do is to digitize them and to apply geo-coordinates to them so I can use them as overlays for openstreetmap data or such. Obviously I cannot put those maps onto my €80 scanner and go. Some of them are really large (1.5m x 1.5m roughly, I believe) and they need to be treated with great care because the paper is partly damaged. So firstly I need a method or service provider that can do the digitizing without damaging them. Secondly I need a hint what the best method is to apply geo coordinates to those maps then. The maps are old and landscape and places have changed, it maybe difficult to identify exact spots. So: are there any experiences or tips I could use?"
I have a map of the U.S. - its actual size. The legend says "1 mile = 1 mile".
People ask me where I live and I say, "E4".
It must have been something you assimilated. . . .
I guess you should have used a more up to date map.
Take photographs of them and put them on the internet. Google will automagically index them and add them to their street maps in real time.
