I want to dissolve polygons from layer1 witch overlap with polygons of layer2 keeping attributes table of layer1 and using command line.
What I've done :
v.in.ogr -o input=original_plygons output=layer1 v.in.ogr -o input=plygons_to_add output=layer2 v.patch -a input=layer2 output=layer1 (v.dissolve input=layer1 output=dissolved column=??? )
the problem is to dissolve you should chose a column ! and after the patch (merge) the overlapping polygons of layer2 doesn't have a common same value to dissolve them correctly...
Can you please help me to solve this problem ?
