thanks, I have already working script [1]. Anyway this approach is not possible because of the number of the generated lines (for the first sample I have to generate more then 2e4 lines). Sure, you can generate lines directly in PostGIS, but it would be nice to have something in GRASS. The more lines you need to generate the longer list of categories will be, not possible to give the list as the parameter. Then v.edit could read categories from stdin, simillary to v.net.path. Hm, what about v.net? New tool to generate network from points? v.net input=points output=net operation=lines line_file=- << EOF 1 1 2 2 2 3 EOF creates edges between points 1-2 and 2-3 with category 1 and 2?
