Geospatial modeling system providing simulated tree trunks for groups of tree crown vegitation points and related methods
TLDR
In this article, a tree crown vegetation points are extracted from the geospatial model data for each tree of a plurality of trees, and a tree trunk is generated from the points.Abstract:
A geospatial modeling system (20) may include a geospatial model database (21) containing geospatial model data, a display (23), and a processor (22). The processor (22) may cooperate with the geospatial model database (21) and the display (23) 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 (22) may generate each simulated tree trunk to have a tree trunk height (h) based upon heights of the respective group of tree crown vegetation points.read more
