[GRASS-user] intersection of network-lines and areas

[achim]

Hello,

I cannot find a solution for extracting those areas that are crossed by
a line. And further to find out, what areas are crossed by a network of
lines in order to union them into one area.

Its for combining subbasins which are part of a certain rivernetwork.

Has someone experience? Any hints are welcomed.

Thanks in advance,
achim
