1. A geospatial modeling system comprising:
- a geospatial model database; and
a processor cooperating with said geospatial model database for identifying a building roof type defined by building roof data points as being from among a plurality of possible building roof types based upon applying multi-directional gradient Robert'"'"'s cross calculations to the building roof data points using a grid centered for each building data point, summing distances of opposite sides in the grid, and identifying building roof data points whose sum is within a threshold from zero as being localized peak data points, the multi-directional gradient Robert'"'"'s cross calculations comprising eight-way Robert'"'"'s cross calculations.

Abstract
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.
