Surface Modeling
Technical Guides & other documentation
The Surface Modeling process allows you to construct and transform representations of natural terrains and mathematical surfaces from the 3D information you provide. The Surface Fitting, Contouring, and Triangulation operations allow you to produce Digital Elevation Model rasters (DEMs), contour lines, and triangulated irregular networks (TINs), respectively. The input for each operation can be any one of the terrain representations described above or 3D point data. Elevation values can be read directly from the 3D object or assigned by query from any numeric field in its attribute database. The process provides fast, efficient processing of even very large datasets.
