R: Re: [GRASS-user] problems with v.edit

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

?

Hi
all,
the point is 6 meters far from the line and I used a threshold of
100 meters.
Thanks you all,
Chiara.

Hi,

2009/1/21 chiaraercoli@tiscali.it <chiaraercoli@tiscali.it>:

v.edit map=ret_125
tool=select thresh=$ris_edit coords=$x,$y
the point is 6 meters far from the line and I used a threshold of
100 meters.

so should I understand that result of tool=select no feature is found?
Can you send me sample data?

Martin
