How Kriging works.
Kriging is an advanced geostatistical procedure that generates an estimated surface from a scattered set of points with z values. Unlike the other interpolation methods, Kriging involves an interactive investigation of the spatial behavior of the phenomenon represented by the z values before the user selects the best estimation method for generating the output surface.
