Altering the anisotropy parameters when modeling semivariogram and covariance functions

Available with Geostatistical Analyst license.

1. Set the Anisotropy flag to True on the Semivariogram/Covariance Modeling dialog box.

   The Major Range, Minor Range, and Direction controls appear.

2. Click the calculator icon next to Major Range. The icon changes to a pencil icon and the input box becomes active). Type the desired length of the range.
3. Click the calculator icon next to Minor Range. The icon changes to a pencil icon and the input box becomes active). Type the desired length of the range.
4. Click the calculator icon next to Direction. The icon changes to a pencil icon and the input box becomes active). Type the desired angle.

Tip:

The pencil icon next to the Major Range, Minor Range, and Direction input boxes allows you to edit the input values. By clicking the calculator icon (the icon toggles between a calculator and a pencil), the optimal values are calculated and set for the input parameters.
