Variable Orientations

For Kriging and other estimations, structural trends do not provide the needed control over the anisotropy ratios, among other considerations. For this purpose, variable orientation can be used.

Variable orientation provides a similar control over the changing direction of anisotropy for the purposes of improving local value estimates, orienting the search space and variogram according to local characteristics. Variable orientation is visualised using lines or, as in this illustration, flat disks with a line indicating the orientation of the maximum axis direction for each search space local to each centroid. Here the disks have also been coloured reflecting the Dip direction.
