In further text, theory behind kriging with external drift and regression-kriging and differences between them are explained in more detail. WebThree main variants of Kriging can be distinguished, (Goovaerts, 1997): – Simple Kriging (SK), which considers the mean to be known and constant throughout the study area; – Ordinary Kriging (OK), which accounts for local ﬂuctuations of the mean, limiting the stationarity to the local neighbor-30 hood. In this case, the mean is unknown. 3
