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
I get:
0 of 113126 features selected from vector map <[EMAIL PROTECTED]>v.edit
complete.
the option query=select does work for me with a suitably large
negative threshold.
So far, my solution is this:
v.edit map=roads tool=snap thresh=5 snap=node \
coord=`v.build roads op=dump | grep "n_lines = 1" | awk -F '=' '{gsub
(/ /,"");printf("%s,", $4)}'
This parses dangling nodes from v.build's topology dump.
This works, but I can only feed about 16k sets of coordinates into
v.edit.
Is there some magic I'm missing here?
I'm using GRASS 6.3 cvs (about a month old) on Mac OS X
