Template:GMS 2D Interpolation Method

The following 2D interpolation methods are supported by GMS:

• Linear – Uses data points that are first triangulated to form a network of triangles.
• Inverse Distance Weighted – Based on the assumption that the interpolating surface should be influenced most by the nearby points and less by the more distant points.
• Clough-Tocher – A finite element method because it has origins in the finite element method of numerical analysis.
• Natural Neighbor – Based on the Thiessen polygon network of the point data.
• Kriging – Based on the assumption that the parameter being interpolated can be treated as a regionalized variable.

Log interpolation is also supported.
