Interpolating Angles into a Geological Model with ESTIMA

Note: COKRIG also provides Dynamic Anisotropy support. See Dynamic Anisotropy with COKRIG

Once the dip and dip direction data has been created, the next stage is to interpolate the two sets of angles into the block model. However, it is not possible to use the standard interpolation methods in ESTIMA as angle data is circular – for example the average of 340° and 30° is 5°. IMETHOD=8 has all the functionality of inverse power of distance (IMETHOD=2) but can be used with angular data.

Therefore interpolating the angular data can be done through the standard ESTIMA process using IMETHOD=8.

The angular data option has also been added to the ESTIMATE dialog as a check box adjacent to the Inverse Power of Distance method.
