Anisotropic Kriging

Anisotropic Kriging can be seen as a point interpolation, which requires a point map as input and which returns a raster map with estimations and optionally an error map. Anisotropic Kriging is a variant of the Ordinary Kriging operation: Anisotropic Kriging incorporates the influence of direction dependency.

Before Anisotropic Kriging, you should investigate the direction of anisotropy for instance with Variogram Surface, the semi-variogram values in two directions for instance with Spatial Correlation, and determine the range of the semi-variogram values in two directions by preparing semi-variogram models in a graph window (Graph window : Add semi-variogram model).
