Companion Notebook: Rotation Conventions

Correctly specifying angles of anisotropy is critical, and one of the most misunderstood steps in resource modeling. It affects experimental variogram directions, search ellipsoids for estimation and simulation, and coordinate systems aligned with geological boundaries.

The original Geostatistics Lesson by Matthew Deutsch explains angle specification and rotation conventions. Ben Harding and Matthew Deutsch have created a Python companion notebook detailing angle specifications, rotation matrices and their practical application in 2D and 3D.
