Kriging-Software

[Sheilah Nolan]

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.

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.
