GEOSPATIAL MODELING SYSTEM FOR PERFORMING FILTERING OPERATIONS BASED UPON A SUM OF DIFFERENCES OF A GIVEN AND NEIGHBORING LOCATION POINTS AND RELATED METHODS

摘要

A geospatial modeling system (20) may include a geospatial model database (21) and a processor (22) cooperating therewith for performing at least one noise filtering operation on data comprising elevations associated with respective location points. The at least noise filtering operation may include determining a respective center point elevation difference for each location point (45) and based upon a sum of differences between elevations of a given location point and a plurality of neighboring location points.
