[GRASS-user] clipping line data to a polygon

[M S]

Is the best way to clip data to use the v.overlay command with the "and"
operator?

it works great, but seems quite slow on larger datasets.  Additionally as an
example, if i have topographic contour lines, and i want to clip them to a
polygon, and only want the topo line attributes (elevation) outputted, is
there a way to do this?  Is there another way to clip line data to within a
polygon that might be a bit faster?

thanks,
Mark
