Kriging

Kriging is a sophisticated interpolation algorithm and is the preferred method when interpolating geodata. The core of the Kriging algorithm is basically Inverse Distance Weighting but the weighting is based on a statistical analysis of the data called a variogram.

A detailed description of Kriging is beyond the scope of this documentation. See: http://en.wikipedia.org/wiki/Kriging for a summary description and references.

GSLIB
In GeoScene3D Kriging is performed with GSLIB. GSLIB is an acronym for Geostatistical Software LIBrary, and is a collection of geostatistical programs developed at Stanford University. GeoScene3D provides a fully integrated interface to this software package.

The necessary GSLIB executables are installed with the ordinary installation af GeoScene3D (gamv.exe, vmodel.exe, kt3d.exe). The full version of GSLIB can be downloaded from http://www.gslib.com.

GSLIB is configured through the GeoScene3D user interface. Documentation of the numerous GSLIB parameters are beyond the scope of this text. A full reference to GSLIB can be found in: GSLIB, Geostatistical Software Library and User's Guide, Second Edition, Clayton Deutsch and André Journel, 1997, Oxford University Press.
