[GRASS-user] Surfaces with faults

[bonushenricus]

Hello
I would like to use the procedure described in "Open Source GIS: A
GRASS GIS Approach" second edition page 191 "7.3.5 Surfaces with
faults".
I have a survey of points. Some points are two ditches. I have run a
v.surf.rst with the survey points without the ditch.
Attached is the ascii file of the ditch points (EPSG:32632)
I have therefore operated as follows:
> v.in.lines -z --overwrite input=fosso.dat output=fosso_linea /
> separator=comma
> g.region vector=fosso_linea res=0.2
> v.to.rast -d --overwrite input=fosso_linea type=line output=fosso /
> use=z
> v.surf.rst --overwrite segmax=60 npmin=100 dmin=1 dmax=6 /
> input=fosso_linea elevation=fosso_dem mask=fosso
the result is with no_data

Some suggestions?
