Patent ID: 8503761

Claim:
A geospatial modeling system comprising: a geospatial model database configured to store a digital surface model (DSM) of a geographical area, and store image data of the geographical area, the image data having at least one spectral range indicative of a difference between buildings and vegetation; and a processor cooperating with said geospatial model database and configured to separate bare earth data from remaining building and vegetation data in the DSM to define a building and vegetation DSM, register the image data with the building and vegetation DSM, correlate a plurality of image pixels from the image data to a given point in the building and vegetation DSM, form a voting space including the correlated plurality of image pixels, and classify each point of the building and vegetation DSM as either building or vegetation based upon the at least one spectral range of the image data, the classifying comprising classifying each pixel of the voting space as either building or vegetation based upon comparison to a threshold, and determining the given point as vegetation if a majority of the voting space is classified as vegetation and determining the given point as a building if a majority of the voting space is classified as building.
