Abstract
In a method for obtaining a three-dimensional map representation for a navigation system from digital, two-dimensional road map data, the road map data for a field of view that is to be represented and has a predetermined visual range are curved in a radially symmetric fashion about a virtual viewpoint by means of a polynomial transformation. A navigation system suitable for generating such a map representation is distinguished by a conversion unit with the aid of which two-dimensional road map data can be transferred into a view curved in a radially symmetric fashion.
