Re: AI-GEOSTATS: OSSFIM
OSSFIM calculates block kriging prediction errors as a function of data grid
spacing, block size, and variogram model
Any block kriging program can do this for you, but OSSFIM tries to do it in
an organized way, varying (IIRC) block size and data grid spacing given
a variogram model. To do this with e.g. GSLIB or (plain) gstat would be a bit
of an effort.
I wrote the web interface to OSSFIM, http://www.gstat.org/ossfim.html a few
years back. It is not based on the OSSFIM fortran code,but uses gstat. The
page also tells you:
Differences from the original OSSFIM version
The original OSSFIM program by McBratney and Webster has more options than this
it can handle triangular grids, it can handle the case where the block is
centered around a sample point, and it deals with variograms with anisotropy.
calculate block kriging standard errors in all these cases, but not through
You can run it as a stand alone program using
gstat -e ossfim [arguments]
the arguments are not documented, you have to run a few html versions
(http://www.gstat.org/ossfim_form.html ) to see how it works.
