Abstract
In a method for obtaining a three-dimensional map representation for a navigation system from two-dimensional road map data, road segments to be represented are linked with the aid of three-dimensional topological data. The navigation system has a conversion unit for converting the two-dimensional road map data and the three-dimensional road topological data into a three-dimensional map representation.
