The more lines you need to generate the longer list of categories will
be, not possible to give the list as the parameter. Then v.edit could
read categories from stdin, simillary to v.net.path. Hm, what about
v.net? New tool to generate network from points?
v.net input=points output=net operation=lines line_file=- << EOF
1 1 2
2 2 3
EOF
creates edges between points 1-2 and 2-3 with category 1 and 2?
better
v.net points=points output=net operation=net file=- << EOF
1 1 2
2 2 3
EOF
What do you think about that?
I think that a GRASS module for connecting lines between chosen points
is a definite yes (think of point coordinates of airports with
information about flight connections between airports). Up to now I've
been doing it with a simple script + v.in.ascii.
Not sure v.net is the most logical place to have this. Maybe a
stand-alone module v.points2lines ?
