Hi devs,
Does GRASS have any geostatistical tools. HPGL is ahigh performace library for geostatistics

Simple Kriging (SK)
Ordinary Kriging (OK)
Indicator Kriging (IK)
Local Varying Mean Kriging (LVM Kriging)
Simple CoKriging (Markov Models 1 & 2)
Sequential Indicator Simulation (SIS)
Correlogram Local Varying Mean SIS (CLVM SIS)
Local Varying Mean SIS (LVM SIS)
Sequential Gaussian Simulation (SGS)

are available in HPGL so let me know the comments and suggeation before integrating HPGL to GRASS GIS

Thanks && Regards
Rashad

Rashad,

Geostatistics is done on GRASS in conjunction with R and it's geostatistical packages, which you can find here:

http://cran.r-project.org/web/views/Spatial.html

R is found here: http://www.r-project.org/

Also, a standalone package (found in R) gstat can be found here: http://gstat.org/

You may also want to look here http://casoilresource.lawr.ucdavis.edu/drupal/node/438 for some applications

Good luck,

Tom

Hi Rashad,

I'd be interested to hear about HPGL. As Thomas mentioned, kriging is
currently available through R using the gstat package - and has thus
the some limitations in terms of efficiency, and also on the size of
the data to be processed.

Note that from 6.4, a python module is available for kriging (see
v.krige.py). It is in the trunk for 7.0.

Cheers,

Pierre
