I have shapefile with many topology errors. Most of there are
When I'm import in GRASS It create, for all overlapped areas a link in
layer 2 and in layer 1 it create two category for each centroid.
It is possible extract only areas where each centroid are linked to only
one category or extract only areas where no link to layer 2 exist?
