[GRASSLIST:10534] v.surf.rst and scripting

[Luca Casagrande]

Hi guys!

I created a DEM starting from a point vector layer using v.surf.rst in classic 
way:

Now i wanna try the CV procedure. Reading on manual:
[...]To find "optimal parameters", the CV procedure must be iteratively 
performed for all reasonable combinations of the approximation parameters 
with small incremental steps [...]

Has anyone ever created a script like this one?

The only thing that i don't understand is if i can found approximation 
parameters using a small part of my region (for speed up everything 'cause 
the region is so big) or i need to use the whole region...

P.S.
Talking with Markus on GRASS irc chat ( irc://chat.freenode.net:6667/#grass ), 
I can add a part about v.surf.rst on the GRASS wiki, so if anyone has got 
experience or other info about using this command, contact me to talk about 
it.

Thx 
Luca
