04 Directional Variography

Learn how to specify lag distances, set up variogram searches using the sphere method to automatically sample 40 directions in 3D space, and calculate experimental variograms. We then walk through the process of fitting these experimental points using specific restrictions for angles and ranges across multiple variogram structures. Finally, discover how to visualize the quality of the fit with grid plots and review the fitted variogram parameters.
