Methods of the linear geostatistics (Kriging)

Abstract

Estimation is most commonly made using Ordinary (OK) or Simple (SK) Kriging, which are the variants of the basic linear regression techniques allowing estimation of a single regionalised variable in unsampled locations. Kriging technique imposes the following special constraints on the estimate: • It minimises an estimation error • It assures that mathematical expectation of the estimation error is equal to zero. These characteristics give advantage to kriging in comparison with other linear estimators.
