I'm surprised this has not been mentioned yet but there is GRASS GIS available at http://grass.itc.it/ I have not tried it personally so I don't know what type of learning curve is involved.

Subject: Rubbersheeting !
 
I was wondering whether anyone has some ideas on rubbersheeting, the
overlaying on two (historical) plans on each other and adjusting to make the
best fit. I know this is done by high level GIS programs but I was wondering
whether anyone has some ideas on how to do this that doesn't involve me
buying Arch View!
