Hi all,
Trying to use v.net.distance or v.net.iso on my network, I
have found some gaps in it. Namely some roads are cut in the
middle, thus distorting the results. I am looking for the
easiest way (a function or so) to fix, overcome such
problems/fixing the network, probably using a threshold or so.
You can try v.edit tool=snap thresh=...
The threshold will be in the units of the coordinate system, so
probably meters.
But you'll have to be careful. THis might snap road ends that you
don't want to snap. (like any automated procedure). If, on the other
hand, the gaps are small, this method might help.

I am aware of 2 hard solutions:
- fix it manually
- get a better layer of roads
However, since I'm working on the national scale the first
one will take forever and the second is problematic due to
data scarcity.
Best,
Dor
