Interpolation Method
The Interpolation Method option in Contour Options only applies if Contour Data = Data Column (i.e., you are plotting general data on the stereonet rather than vector densities). The following options are available:
- On Sphere – interpolation is carried out directly on the sphere
- Thin Plate Spline – interpolation is carried out on the 2D stereonet using a Thin Plate Spline method
- Local Thin Plate Spline – interpolation is carried out on the 2D stereonet using a Local Thin Plate Spline method
