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
