Abstract
A navigation method and apparatus uses routing data created by a remote navigation server for a route guidance operation by an individual navigation system. The navigation method and apparatus makes use of the most currently updated map data and the high calculation power of the remote navigation server for creating the calculated route and utilizes the calculated route for the route guidance operation by the individual navigation system. The navigation method and apparatus decreases an amount of routing data indicating the calculated route by employing a concept of strategic road segments for sending the routing data to the individual navigation system. The individual navigation system recreates the calculated route based on the routing data received from the navigation server for the route guidance operation to the destination.
