Hi Mark and others,
I figured out where the error I'm getting from v.net.components is
coming from. I just don't know how to fix it.
The problem is that when I clean my roads network it's breaking some
lines and these are kept with the same categories. So when I run
v.net.components it tries to calculate the connectivity of the
components based on the cat value. Since there are some repeated values
for broken roads, it can't continue. So I believe I need to get new cat
values for the network. Just don't know ow to do it (been away from
GRASS for a while)...
How can I get new cat values? And can I keep the old values in order to
keep the DB link to the roads network?
v.category option=add.
You can create new cat values on another layer and keep the old ones on
layer 1.
