A geospatial modeling system may include a geospatial model database and a processor. The processor may cooperate with the geospatial model database for extracting ground data from foliage and building data, performing at least one noise filtering operation on the foliage and building data comprising at least one sum of differences operation, and separating foliage data from the building data based upon the at least one noise filtering operation.
