[GRASSLIST:993] extracting nodes of three or more lines

[Jonathan Aguero]

Dear List

I have a road map file in GRASS and I need to extract all nodes of this map
that connect three or more lines and create a point map (intersections).
After that I need to join the intersection map category to the road segments
so that I can later aggregate road segments table by intersections. Can I do
this with GRASS? 

Thanks.
