Abstract
A computer implemented method is for processing a digital elevation model (DEM) including data for a plurality of objects. The method includes determining a perimeter versus area parameter for each object in the DEM, and comparing the perimeter versus area parameter for each object to a threshold to identify whether each object in the DEM is a building or foliage.
