What kind of program is this ? I have been trying to find something like this for some time now.There are programs in which you can scan ANY scaled map into a computer, then register 2 or 3 known GPS co-ordinates, then plot a course or get co-ordinates for a location anywhere on the map. I wanted to try this with a 1863 CSA map to help find housesites, but I have found the 1863 map is not all the well drawn to scale, but works ok if you have a nearby known location.
