I started writing such a program (from
@Book{ deutsch92,
author = "Clayton V. Deutsch and Andr\'{e} G. Journel",
title = "{GSLIB}: Geostatistical Software Library and User's
Guide",
publisher = "Oxford University Press",
year = "1992",
address = "New York, " # NY,
cost = "\$49.95"
}
) but ran out of time. It's on
my list of things to do, but it's pretty low. I would encourage
any aspiring programmer to work on this.
As mentioned, I have programs to calculate sample semivariograms (s.sv)
and fit common models (m.svfit). These are what Martin was talking
about. They are at:
ftp://pasture.ecn.purdue.edu/pub/mccauley/grass
FWIW, there's an unfinished program for kriging (by someone else) in
that directory--it needs to be ridden of Numerical Recipes code. I can
also make my unfinished program available if anyone is interested.
