Abstract
In certain embodiments, path determination includes receiving terrain elevation data comprising elevation values for locations of an area, where each elevation value indicates an elevation at a location. One or more gradient matrices are calculated from the elevation values. Each gradient matrix comprises gradient values corresponding to the locations. Traversable segments are determined from the gradient matrices, and a path is determined from the traversable segments.
