Abstract
A method for operating a navigational system, especially a navigational system for a motor vehicle, having a memory, a display unit and at least one operating element, map data being loaded from a map data memory into the memory; the map data being subdivided into first map data and second map data; the first map data including geometric data of edges of a map network stored as graphs, and the second map data including topological data and applications being carried out using the first and/or second map data loaded into the memory.

11. A method for operating a navigational system for a motor vehicle, the navigational system including a memory, a display unit and at least one operating element, the method comprising:
-
loading map data from a map data memory into the memory, the map data being subdivided into first map data and second map data, the first map data including geometric data of edges of a map network stored as graphs, and the second map data including topological data; and carrying out navigational applications using at least one of the first map data and the second map data loaded into the memory. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A navigational system, comprising:
-
a memory storing selected map data from a map data memory; a display element; at least one operating element; and applications adapted to access the memory and the map data stored in the memory, the applications adapted to load the map data memory into the memory, the map data being subdivided in a first map data and second map data, the first map data including geometric data of edges of a map network stored as graphs, and the second map data including topological data.

20. A storage medium storing a digital map having map data, the map data being subdivided into first map data and second map data, the first map data including geometric data of edges of a map network stored as graphs, and the second map data including topological data, the storage medium further storing applications, which, when executed by a processor, cause the processor to perform the steps of loading the map data into memory, and using the first and second map data.
