Using Software to Compare Maps/Map Versions

Question

I am considering buying a software package for comparing maps.  I'd like advice on what level of the Adobe Family will do the job I want do, if any will.  I need to take scans of historic maps, some current and digital, some hand-drawn in the 19th century and comapre them.  The maps will, obviously, be of varying scales and of greater or lesser cartographic accuracy.  What I'd like to be able to do is pull in a current base map of an area, scan in the older version, open both in different layers of the same image and adjust the second to match the base as closely as possible by specifying corresponding points (road intersections, mountain peaks, river courses) that correspond.  After identifying corresponding features for the program, I'd like it to try to fit the layers to each other as closely as possible, both with and without distortion of the images.  The "without" option is necessary because I cannot presume that a certain road has not been re-aligned or that the riveer has not changed course in the period between maps.  I'd also like to be able to overlay and match aserial photographs to maps in the same way.
Any advice on which Addobe or other product is best in this aplication would be greatly appreciated.  If I have not been clear, please let me know.

Answer 1

Free: place the map on V1, place a red circle on V2, keyframe the circle to move on your desired route.

And that's pretty much all your options for FCE. Note that the second option is not $100 just for the line generator, it also includes a bunch of other handy stuffy.
