Creating a TIN surface

A Triangulated Irregular Network (TIN) is mesh of non-overlapping triangles that represent a continuous surface. This surface is built by triangulating a set of points that have z-values using the Delaunay triangulation method. This method generates triangles that are as near as possible to an equilateral triangle. The set of points represent the primary source of height values (mass points) and incorporates point features or vertices of the polyline and polygon features.

Note

For theoretical aspects about TIN and Delaunay triangulation, please refer to David O'Sullivan and David Unwin, Geographic Information Analysis, John Wiley & Sons, Inc., 2003, page 28 and 215 to 220.
