Cheers, Brian. (Sat Jan 12 14:25:02 2013) v.build map=MaskVector@user1 Building topology for vector map <MaskVector@user1>... Registering primitives... 184 primitives registered 4948 vertices registered Building areas... 110 areas built 91 isles built Attaching islands... Attaching centroids... Number of nodes: 101 Number of primitives: 184 Number of points: 0 Number of lines: 0 Number of boundaries: 120 Number of centroids: 64 Number of areas: 110 Number of isles: 91 (Sat Jan 12 14:25:02 2013) Command finished (0 sec) On Sat, Jan 12, 2013 at 12:52 PM, Maris Nartiss <[email protected]> wrote: > Please, post output of v.build > > 2013/1/12 Brian Sanjeewa Rupasinghe <[email protected]>: > > Hi, > > > > I used v.category.
