Dylan,
I must be missing something. I put the e/n coordinates for the
upstream/downstream points along the stream into a file called 'nodes'. Than
I ran:
GRASS 6.4.0svn (oregonM):/usr4/grassbase > v.net.path --o in=abernethy_creek
out=stream_length type=line < nodes
and saw this warning:
WARNING: Point 242551.880000,432149.700000 is not reachable from point
0.600000,431305.070000
WARNING: 1 destination(s) unreachable (including points out of threshold)
Here is the contents of 'nodes':
242856.60 431305.07 242551.88 432149.70
Any idea what I've done incorrectly? Those points are on the stream itself
on the map.
Thanks,
Rich
