CA 2597056

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.

L'invention concerne un procédé assisté par ordinateur de traitement d'un modèle de hauteur numérique (DEM) comprenant des données pour une pluralité d'objets. Le procédé consiste à déterminer (bloc 502) un paramètre périmètre-zone pour chaque objet du modèle DEM, et à comparer (bloc 504) le paramètre périmètre-zone de chaque objet à un seuil, afin d'identifier si chaque objet du modèle DEM est un bâtiment (54) ou un feuillage (56).
