You are here: Surfaces > RasterDEMGenerator


Constructs a Delaunay triangulation based on input points and breaklines. That triangulation is then uniformly sampled to produce a raster digital elevation model (DEM raster).

Input Ports



Usage Notes

  • If a set of individual 3D points comprising a DEM is required, you should use the DEMGenerator.
  • This transformer is unaffected by raster band and palette selection.


Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
