[Soc] GRASS module for kriging - call for users [was: R-sig-Geo Digest, Vol 69, Issue 21]

My two cents.
Some of the best interface features I've found in Isatis, one of the
best commercial geostatistical sw I've used, are:

 - interaction with the variogram map to select direction and plot the
ESPs together differentiating the various selected dirs with colors.
It permits to reveal anisitropies structures with a glance.
 - interaction with the variogram model (plotted with the ESP) to fit
it by hand. In practice you can change the model parameters (sill,
nugget, range) by clicking on the plot handles.
 - let the user select pairs from the variogram cloud and visualize
them on the map. It permits, for example, to see where high variances
pairs (linked with a line) are located.

Another useful feature is the visualization of the anisotropy
parameters on the variogram map (the cone). And, last, the possibility
to define visually the neighborhood as circle/ellipse.

Ok, lots of wishes, and I don't know how hard it would be to develop
them. I've just written them to share...

bye,
giovanni
