Abstract
A system and method of constructing a density map is disclosed. The density map is a cellular grid representing local terrain, wherein each cell contains a density vector representing the density of portion of the terrain corresponding to the cell. The density map can be used to classify and characterize the surrounding terrain, which is useful in making a determination of the traversability of the terrain to mobile vehicles.
