Variograms directions

This section of the Directional Variography interface to specify the directions and parameters that are to be used to calculate the variograms.

Two methods of specifying the directions are available. Each method is displayed under a different tab panel.

• Use 3 orthogonal directions
  The options under this tab allow you to calculate 3 mutually orthogonal directions. The tab also provides a tool to check orthogonality, as well as to compute the third direction (after 2 initial orthogonal directions have been provided).
• Use multiple directions
  This tab panel has 2 modes: User-specified directions or a set of directions all orthogonal to a given vector.
