Anisotropy

A semi variogram model is said to have anisotropy if the range of the semi variogram differs with direction. The way in which this is defined is very similar to the way in which the anisotropy of a modelling search ellipse is defined in the modelling menu.

It should be remembered that the semi variogram anisotropy will define the way that the Kriging weights are applied. It does not affect the way the modelling process actually searches for data.
