[GRASS-dev] selecting lines boundary-wise

[Jaime Carrera]

Hi list,

I'm trying to export the boundaries of a vector file, but would like
to avoid duplication of common boundaries. It's easy to know which
boundaries limit a given area, but how can I extract only one
boundary. For example, area 1 has boundaries 6,7,9 while for area 2
these are 8,9. Is there a way to extract the lines of boundary 8 only
for area 2 in order to avoid duplicating it? A comination of
Vect_get_area_boundaries(&Map,area,List) with something else?

Thanks,
Jaime
