subsetting a vector

[jill schuler]

%%To select a zone of raster map in grass we just need
%%to define the region and then
%%
%%r.mapcalc "new.map = old.map"
%%
%%Is there any way to do the same with a vector?
%%I have a very large vector of coastlines and I'm
%%interested only in one particular region.
%%
%%Thanks!

Use v.cutter with a vector layer that defines your area of interest.
Then run v.spag -i to clean-up the cut data.
