Q: How to dissolve vector polygons (or remove tile boundaries of adjacent maps)
A: Dissolving of areas is done with v.dissolve (v.extract -d). If tile boundaries of adjacent maps (e.g. CORINE Landcover SHAPE files) have to be removed, an extra step is required to first remove duplicated boundaries:
Remove duplicated tile boundaries:
v.clean clc2000_patched out=clc2000_clean tool=snap,break,rmdupl thresh=.01
Dissolve:
