Abstract
Methods and apparatus are provided for determining a position of a vehicle with respect to a terrain. The method comprises accumulating data received from at least one sensor device regarding the occupancy of a spatial region between the vehicle and a first geographic region of the terrain, generating an evidence grid that describes the occupancy of the spatial region, identifying the position of the first geographic region of the terrain based on the evidence grid and previously compiled reference data, and determining the position of the vehicle based on the position of the first geographic region of the terrain with respect to the previously compiled reference data.
