[GRASS-user] cross validation v.surf.rst

[Ivan Marchesini]

Hi,
I'm using the cross validation procedure of v.surf.rst

I have around 250 points on a region of 100 square kilometers and I'm
working in a region having 10 meters resolution

When I run a cross validation using v.surf.rst I regularly get the cvdev
file but what it seems strange is that it takes only few seconds to run
on a normal PC with a i7 core.

I suppose that it would had to run the interpolation 250 times but it
seems it runs only one time.

Is this normal?

many thanks

Ivan
