GEOSPATIAL MODELING SYSTEM FOR SEPARATING FOLIAGE DATA FROM BUILDING DATA BASED UPON LOOSE AND STRICT TOLERANCE NOISE FILTERING OPERATIONS AND RELATED METHODS

摘要

A geospatial modeling system (20) may include a geospatial model database (21) and a processor (22). The processor (22) may cooperate with the geospatial model database (21) for extracting ground data from foliage and building data (51), and performing a plurality of noise filtering operations on the foliage and building data comprising a first loose tolerance filtering to determine an inclusive estimate of building locations and a second strict tolerance filtering to reduce false building locations. The processor (22) may also cooperate with the geospatial model database (21) for performing at least one edge recovery operation to compensate for noisy building perimeters, and separating foliage data from the building data based upon the noise filtering operations and the at least one edge recovery operation.
