Hi Everyone,
Can you tell me if GRASS is able to detect change between two input
polyline shapefiles? I have a 5m contour set for two different years at
a particular mine, and I'm looking for a way to automate detection of
the yearly pit advances.
Basically, I'm looking for something to subtract file A from file B
(b-a=change) and output a file showing just the lines that changed
between the two files.
Thanks for any direction you can offer.
Andrew Schroeder
