Abstract: Navigation systems and methods are provided. A classifier is configured to transform a received image of a terrain into a classified image in which patches of pixels from the received image are represented as being in one of a specified number of material classes, each associated with respective terrain parameters. A physical traversability module is configured to determine, for the material parameters, a terrain topography and given vehicle parameters, a degree of traversability of the vehicle through the terrain as represented by the received image, to yield a traversability map. A routing module is configured to derive traversability measure(s) for route(s) through the classified image and with respect to the traversability map, between a given origin and a given destination or within a region with respect to a user-defined mission. A graphical user interface is configured to display the route(s) according to the traversability measure(s).
