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 includes determining (Block 502) a perimeter versus area parameter for each object in the DEM, and comparing (Block 504) the perimeter versus area parameter for each object to a threshold to identify whether each object in the DEM is a building 54 or foliage 56.
