Agnès, Variogram graphs for a number of directions can be represented in one map of contours. Looking at this variogram contour plot, if there is anisotropy the contour lines will make out the shape of an ellipse. The major and minor axis of the ellipse are then the two directions of minimum and

AI-GEOSTATS:Variogram Surface in the Software Variowin2.2

Hello, In the program VARIO2D with PCF in the software VARIOWIN 2.2, we need to identificate the main directions of anisotropies of the spatial behavior of a variable. For this, we use the Variogram Surface. I didn't quite understand how we use this graph for having directions of anisotropies? I
