Comment: How I would do it (Score 1) 235

I would build an x/y tram and mount a hd digital camera to it. Using a couple of hacks on the camera should be able to remotely trigger it from a computer program. Given stepper motors on the x/y you could control the position of the camera. This setup could be mounted over a table and the map could just lay there. Then do as others have suggested and use stitching software to put the images together.

As part of my job I work with GIS information on a daily basis. I would say the largest issue you are going to run into is getting the map to line up with reality. I know cartographers of old did not have the tools to create accurate maps like we do today. My point being scale may not be constant over the entire map compared to reality. While you may line up one or two points you might find yourself quite off on the others. You might just have to accept it as good enough for government work. I would suggest you look into technologies like geoserver or mapserver. Consequently geoserver has openmaps built into it.
