METHOD AND APPARATUS FOR DISTINGUISHING FOLIAGE FROM BUILDINGS FOR TOPOGRAPHICAL MODELING

摘要

A computer implemented method is for processing a digital elevation model(DEM) including data for a plurality of objects. The method includesdetermining (Block 502) a perimeter versus area parameter for each object inthe DEM, and comparing (Block 504) the perimeter versus area parameter foreach object to a threshold to identify whether each object in the DEM is abuilding 54 or foliage 56.
