Hi,

2009/1/20 chiaraercoli@tiscali.it <chiaraercoli@tiscali.it>:

I have a problem with v-edit.
I have to break a vector line
into two parts near a point. I gave this command:

v.edit map=ret_125
layer=1 type=line tool=break thresh=$ris_edit coords=$x,$y snap=no

where " $ris_edit " depends on the resolution of the DEM raster

map,

"$x" and "$y" are the coordinates of the point.

are you sure that threshold value is enough to select vector feature
which you want to break?

v.edit map=ret_125 tool=select thresh=$ris_edit coords=$x,$y

?

Martin

I send you the line, ret_125, and the point, punto_minimo.
Thanks for all,
