Hi Markus, I must be missing something, because this still does not seem to work. I found another (non-GRASS) way to accomplish this, so the priority is not very high, but I'd still like to figure out the GRASS method. Is the v.patch step in the CORINE example necessary, or mostly just the v.clean step with rmdupl?

Hi Darren, I also stumbled over this problem, but we solved it. The trick is that you first have to remove the duplicated tile boundaries, then dissolve works. See example for CORINE Landcover SHAPE files: http://grass.itc.it/grass63/manuals/html63_user/v.dissolve.html Cheers Markus Darren Cope wrote: > > Hi all, > > I'm new to GRASS, and using it in Windows via QGIS. > > I am attempting to do a "spatial dissolve" (i.e. not dissolve on an > attribute, but rather just remove unnecessary tile boundaries) on a > file that I've imported to GRASS from a shapefile, and am so far > unsuccessful.
