A system for performing a similarity search in a navigation device data base uses a metric index structure. The index structure includes a plurality of nodes. When a query object is received, a node of the index structure which is associated with at least one object is accessed. A distance between the query object and the at least one object is determined in accordance with a distance metric. Based on the determined distance, another node of the index structure is selectively accessed.

Navigation system data base system

A vehicle navigation system includes a map database storing map data. The map data has links representing road segments, road number icons, and additional road information icons. At least one of the links is associated with at least one of the road number icons and at least one of the additional road information icons. The vehicle navigation system may furthermore include a processing unit coupled to the map database and configured to control outputting of route guidance information via an output device. The outputting of route guidance information may include displaying a road number icon and an additional road information icon together with a link if the link is associated with the road number icon and the additional road information icon.
