[GRASS-user] remove line segment from a line vector

[matteo marcantonio]

Hello list,

I'm writing since I need to clean a line vector (road network) removing all
the line segments not connected to other segments. I guess that I need to
remove all the segment that have valence = 0.

I need to remove them to perform a network distance analysis avoiding the
issue of unreachable nodes.

Is there any way to do it?

Thanks for any help

Matteo
