Hi Peter,
Here's some old mail on kriging with GRASS. Hope it helps.
I haven't checked this site or used the software.
My apolgies if this posting is redundant, I lost track of some recent
mail.

We are in search of a Grass algoritme to interpolate DEM's by means of
kriging. I know there exists s.surf.kriging (I checked the archive) but
was not able to find it either in my release (update 5 is included)
either on incoming in Grass. Any one an idea where to find it? We want to
use it on IRIX5.2 so also compiling notes should be most welcome!
Part of what you need is at:
ftp://pasture.ecn.purdue.edu/pub/mccauley/grass
You should look at:
s.sv.tar.gz - sample semivariograms;
m.svfit.tar.gz - semivariogram fitting; and maybe
w.geostat - an unsupported tcl/tk interface.
For the latter, you need tcl/tk installed as well as g.gnuplot
(see ftp://ftp.dartmouth.edu/pub/gnuplot). s.sv and m.svfit
require g.gnuplot (but not tcl/tk). I would be interested
in hearing how well/poor these work under IRIX5.2.
[s.sv/m.svfit may be used with straight gnuplot (if you want
faster graphics). Try tweaking a few things in the include
files if you are interested.]
Now for the sad news: s.surf.krig has *still* not worked
its way to the top of my "to-do" list. At that same URL
is a first attempt by Chris Skelley, but I'm not sure if
it is working. I would welcome help in getting such a program
created.

I am in urgent need of kriging software for a research study.
I have heard that there should be a GRASS-Module for kriging, but I haven´t found it on the net. Does anybody know anything about it ?
I would be glad to hear about this package and others wich are in the public domain.
I have to mention that I know GEOEAS already - but I need to use more than 10´000 samples.
Thanks Peter
