Hi,
I found the v.segment command to break my polylines (see previous letter), but it doesn’t really work for me. Somehow it doesn’t find any primitives on the source layer:
v.segment input=lineament_plines_clean output=lineament_segments llayer=1
Building topology …
Registering lines:
0 primitives registered
Building areas:
0 areas built
0 isles built
Attaching islands:
Attaching centroids: Topology was built.
Number of nodes : 0
Number of primitives: 0
Number of points : 0
Number of lines : 0
Number of boundaries: 0
Number of centroids : 0
Nu! mber of areas : 0
Number of isles : 0
0 points read from input
0 points written to output map (0 lost)
0 lines read from input
0 lines written to output map (0 lost)Here are the layer statistics (those plines really exist):
v.info map=lineament_plines_clean layer=1
