Dynamic Anisotropy: True Dip Angles Converting apparent angles to true angles |
Calculating True Dip Angles
As described in Dynamic Anisotropy - Dip and Dip Direction, the dip values interpolated into the model can be either apparent or true. If they are apparent values then they will need to be converted to true values before they can be used for grade estimation. The process APTOTRUE is designed to perform this function.
Converting Apparent Dip to True Dip
The process APTOTRUE takes as input the model file into which the apparent dip and true dip direction angles have been interpolated using ESTIMA, and creates an output model file that includes the true dip angle. The parameter APDIPDIR defines the apparent dip direction which enables the true dip to be calculated.
Further details can be found in the APTOTRUE Helpfile and Process Description.
