A geospatial modeling system may include a geospatial model database containing geospatial model data, a display, and a processor. The processor may cooperate with the geospatial model database and the display for determining a respective group of tree crown vegetation points from the geospatial model data for each tree of a plurality of trees, and for displaying a respective simulated tree trunk beneath each group of tree crown vegetation points. The processor may generate each simulated tree trunk to have a tree trunk height based upon heights of the respective group of tree crown vegetation points.

A geospatial modeling system may include a geospatial model data storage device, a user input device, and a display. A processor may be included for cooperating with the geospatial model data storage device, the user input device and the display for displaying a geospatial model data set on the display including at least one group of building data points, and displaying a plurality of user-selectable different building shapes on the display based upon the at least one group of building data points. The plurality of user-selectable different building shapes may have different respective feature detail levels. The processor may further replace the at least one group of building data points with a given one of the user-selectable different building shapes based upon user selection thereof with the user input device.

A geospatial modeling system may include a geospatial model database and a processor 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 and based upon a sum of differences between elevations of a given location point and a plurality of neighboring location points.

A geospatial modeling system may include a geospatial model database and a processor. The processor may cooperate with the geospatial database for identifying a building roof type defined by building roof data points as being from among a plurality of possible building roof types. This may be done based upon applying multi-directional gradient calculations to the building roof data points.

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 including at least one sum of differences operation, and separating foliage data from the building data based upon the at least one noise filtering operation.
摘要:
A computer implemented method is for processing an original digital elevation model (DEM) including data for terrain and a plurality of objects thereon. The method includes generating a lower-resolution DEM from the original DEM, and generating an objects-only DEM based upon a comparison of the lower-resolution DEM and the original DEM. The method further includes reducing noise in the objects-only DEM.

A geospatial modeling system may include a geospatial database for storing geospatial data points each having respective elevations associated therewith. The system may further include a processor for data thinning the geospatial data points by selecting discriminant points therefrom. The processor may select discriminant points based upon: (a) identifying a current patch having a plurality of spaced-apart current geospatial data boundary points; (b) selecting a current discriminant point within the current patch based upon sequentially stepping through the geospatial data points therein to determine respective elevation differences relative to the current geospatial boundary points and comparing the elevation differences to a threshold range; (c) identifying a plurality of new patches, each having a plurality of spaced-apart new geospatial boundary points including the current discriminant point; and (d) iteratively repeating steps (b) and (c) for each of the new patches until no further new discriminant point is selected.

A geospatial modeling system may include a geospatial model database and a processor cooperating therewith for filtering geospatial model data. This may be done by selectively updating a target point based upon adjacent points lying along a plurality of radial line segments extending outwardly from the at least one target point.
