Hi all,
Does anybody have a suggestion for subtracting the elements in one
line vector from another line vector?

Hi all,
I have two nearly identical line vectors, and I would like to
extract the lines that differ between the two vectors into a third
vector. Specifically, I want to isolate the connecting lines that
were generated by v.net operation=connect. Something like:
[map_C = map_A NOT map_B] for line features.
I thought I would be able to use v.overlay with operator=not, but it
it appears to require that btype=area. It also appears that v.select
allows only operator=overlap.
Can someone point me in the right direction?
I am using William Kyngesburye's 6.4.0RC3 on MacOS 10.5.7.
Thanks,
