I am returning to GRASS after a 10 year hiatus and I must say that I am
I am working on some simple network analysis (road distances from a
point) and want the output to appear as concentric rings. I think I
need to use v.net.iso on my road network but it appears from the manual
that the output from v.net.iso is a line file. I'd like to push that
out to a polygon to get concentric rings so it looks like I need a few
more processing steps.
Like I said, it has been a long while since my GRASS4.0/4.1 days - what
would people suggest using to push the output of v.net.iso out to a
polygon ? v.surf.idw, v.surf.icw, v.hull ? Aren't these all point
interpolations and I need to interpolate from lines ?
Thanks in advance !
