The 2D Kriging (kb2d) program is a small program designed for people learning about kriging and needing a simple program to see how it works. kb2d does 2-D point or block kriging with simple or ordinary kriging. This program is not designed for practical kriging applications; the next program should be used.

The 3-D Kriging Program (kt3d) is a general purpose kriging program for different types of kriging. The program will perform kriging on a grid, cross validation, and jackknife. This program could be tweaked to perform virtually any type of kriging (of course, there is the cokriging and indicator kriging program).

A 3-D Cokriging Program (cokb3d) is available in GSLIB to illustrate the potential of cokriging and provide a simple implementation for cokriging one variable using one or more secondary covariates.

The Indicator Kriging Program (ik3d) provides for indicator kriging with hard and soft indicator data. The use of soft indicator data requires some attention. In all rigor, a form of cokriging should be used for soft indicator data. The output of this program can be post-processed by postik or the probabilities can be mapped directly.
