Variogram Editor

In the main dialog of the variogram editor, a variogram based on input data is shown with a fitted model . The experimental variogram is illustrated as black dots while the variogram model is illustrated as a red curve.

__ Edit: __ A variogram model is autofitted input data.

__

: __

The structure dialog opens, where the autofitted parameters are available, see Structure below.

Note: this documentation describes the user interface and parameters. However, full documentation of variogram analysis and model construction is a complex subject and is beyond the scope of this text.

Note: The dialog is used for both 2D and 3D interpolation. When working in 2D all parameters that are used only for 3D are disabled.

** Structures ** The Variogram Structure is used to edit the parameters for individual variogram model structures.

__ Nugget: __ Nugget effect (has no effect on the Power structure).
TIP: When Nugget = 0 the fitting is disabled.
__ Contribution: __ Contribution or scale of the structure.
__ Structure Type: __ Available structures are: Spherical, Exponential, Gaussian, Power, and Cosine Hole.

Tip: The Spherical and exponential structures are the most common structures to use.

__ Angle 1 __ : Clockwise rotation angle of Y-axis from north.
Angle 2 : Vertical rotation angle of (rotated) Y-axis from horizontal. Used in 3D only.
Angle 3 : Rotation around (rotated) Y-axis (plunge). Used in 3D only.
AHMax: Horizontal range in primary direction of anisotropy (rotated Y-axis).
AHMin:Horizontal range in secondary direction of anisotropy (rotated X-axis).
AHVert: Vertical range in direction of lowest anisotropy (rotated Z-axis). Used in 3D only.

Add: Adds a new default structure to the variogram model.
__ Delete: __ Deletes the selected structure
__ Fit: __ Fits structure type to data

__ «: __ The structures dialog closes

__ Advanced: __ Opens the advanced variogram settings dialog, Advanced Variogram Settings
Simulation: Opens a Variogram simulation window enabling visualization of a variogram realization
