GEOSPATIAL MODELING SYSTEM PROVIDING BUILDING GENERATION BASED UPON USER INPUT ON 3D MODEL AND RELATED METHODS

摘要

A geospatial modeling system (30'') may include a geospatial model data storage device (31''), a user input device (34''), a display (33''), and a processor (32'') cooperating with the geospatial model data storage device, the user input device and the display for displaying a three-dimensional (3D) geospatial model data set on the display, displaying a building boundary around a user-selected building area responsive to the user input device, and generating a histogram of height values within the selected building area. The processor (32'') may also be for determining a building height based upon the histogram of height values, generating a building shape based upon the user-selected building area and the determined building height, and replacing data within the user-selected building area based upon the building shape.
