Abstract
A method for processing digital map data for route determination is provided that includes dividing a region into a plurality of zones, and for the zones, automatically determining at least one cost value for at least one direction of travel of the zone based on the digital map data of the zone and a predetermined cost criterion. A method for determining a route between two points is provided that includes dividing a region into a plurality of zones, for the zones, automatically determining at least one cost value for at least one direction of travel of the zone based on the digital map data of the zone and a predetermined cost criterion, and automatically determining at least one sequence of zones connecting the two points, where each zone of the sequence may be adjacent to another zone of the sequence, such that the sum of the cost values of the zones of the sequence may be optimized.
