Hi, 2008/2/27, David Mahoney <[EMAIL PROTECTED]>:
I rewrote today query=dangle part of v.edit to use the algorithm of v.clean tool=rmdangle|chdangle (lib/vector/Vlib/dangles.c). I am not sure if it can solve your problem. I also added possibility to define different threshold values for coordinates selection, snapping and querying. > I've been trying to use v.edit to snap dangling lines after patching > together a bunch of maps. However, the query=dangle option does not > seem to work. I've tried: > v.edit map=roads tool=select query=dangle thresh=0 > v.edit map=roads tool=select query=dangle thresh=-0 > v.edit map=roads tool=select query=dangle thresh=10000 > v.edit map=roads tool=select query=dangle thresh=-10000 (from Spearfish, selecting dangles shorter then 100 map units) v.edit map=roads tool=select query=dangle thresh=-1,0,-100 --v 35 of 825 features selected from vector map <[EMAIL PROTECTED]> to snap selected features in threshold 5 map units $ v.edit map=roads tool=snap query=dangle thresh=-1,5,-100 --v Threshold value for querying is -100.00 35 of 825 features selected from vector map <[EMAIL PROTECTED]> Threshold value for snapping is 5.00 ---------------------------------- All vertices : 86 Registered points : 83 Nodes marked as anchor : 80 Nodes marked to be snapped: 3 Snapped vertices : 3 New vertices : 0 ---------------------------------- [snip] > I'm using GRASS 6.3 cvs (about a month old) on Mac OS X Hope it helps.
