Hello list,
I have two questions concerning v.dissolve. As far as I can see, there can be only one single column be specified as dissolve item. But I need to dissolve polygons using several items (up to 6) in one stroke. I checked out v.extract, too, hoping that a SQL statement might help me out, but I can only use a WHERE clause (not a GROUP BY clause). Maybe it could help to produce one special concatenated dissolve item before running v.dissolve, but I was hoping to find a more "elegant" way. Second, how can I determine if the output of v.dissolve is Multipart or Singlepart? In my special case, I need both (one for map labeling, one for area statistics). I could not find an option to set Singlepart or Multipart. Thanks a lot and best regards, Uwe
