Create, edit, and utilise surface models. TerraModeler creates surface models (TINs) from various sources, such as LiDAR points stored in binary files or loaded in TerraScan, XYZ ascii files and graphical design elements.

The software offers versatile visualisation options including coloured shaded surfaces, contour lines, grids, coloured triangle nets, elevation texts, slope directions and textured surfaces (in combination with TerraPhoto).
