Abstract
A computer implemented method is for processing an original digital elevation model (DEM) including data for terrain and a plurality of objects thereon. The method includes generating a lower-resolution DEM from the original DEM, and generating an objects-only DEM based upon a comparison of the lower-resolution DEM and the original DEM. The method further includes reducing noise in the objects-only DEM.
