[GRASS-user] Surfaces with faults

[bonushenricus]

Ok
v.to.points creates 2 layer.
The good layer is the 2.
So with
v.to.rast -d input=fosso_punti type=point layer=2 output=fosso_dem
use=z
is correct.
I prefered the way with v.surf.rst from my original survey points, but
the way with v.to.points can help me.
