preserved in the voxel output.
Why not just experiment and check if it produces
a useful result?

Can someone indicate me where can I request simple vector layers of Germany
and France at municipality level?
Thanks!

I can only speculate that you are really
referring to s.vol.idw (?)
As the name implies, this is a module that
uses the now outdated site data model for its
input data. Some of those modules never made
the transition to GRASS 6 and its new vector engine.
It was still around in GRASS 5.3.
They are

interpolation of categories
Check out gstat for the conditional simulation, and TPROGS for the
transition probability. If anything is interested, I have done some
programming to connect GRASS and TPROGS.
Cheers!

Apologies if this is already old news, but I have just been
informed by Alfred de Jager that the great European river catchments

It's very simple. It really just averages the values of raster
cells for a neighbourhood window of a size m x n. It then determines
how much the cell in the window center deviates from that average.
Add some normalization and you get a map that shows you which cells
stick out most. Use it on a map
Hi all,
v.normal's description states:
Tests for normality for points.
However, out of the 15 test metrics it computes, I can't find
a single one that is actually spatial. They all seem to work
on the attribute data only. So why does the description state
that it is for points?
