Class DEMDatasetGenerator

java.lang.Object
  org.deegree.tools.rendering.dem.builder.DEMDatasetGenerator

@Tool(value="Generates DEM multiresolution datasets from rasters, suitable for the WPVS.")
public class DEMDatasetGenerator
extends Object

Tool for generating the binary files for MultiresolutionMesh instances (MRIndex- and PatchData-BLOBs) from DEM coverages (heightfields).

Initially, the domain is divided into two right triangles. These are the root fragments of the multiresolution hierarchy. Smaller fragments (with more detail) are generated by recursively bisecting the triangles.
