Abstract
In order to provide a method for the three-dimensional representation of a digital roadmap, which makes greater use of areas near the horizon of the visual representation and provides the user with supplementary information, a provision is made to draw in these areas navigation or orientation-related information as image elements.

1-11. (canceled)
A method for a three-dimensional representation of at least a part of a digital roadmap in a navigation system, comprising:
- selecting topographical information from data stored in a storage medium as a function of a position and a direction of travel of a motor vehicle;
- converting the topographical information by using a coordinate transformation into a visual representation of the digital roadmap corresponding to a virtual elevated visual focus such that the visual representation of the digital roadmap has a first area containing the topographical information and a second area separated from the first area by a horizon;
- and
- in the second area, drawing at least one of navigation and orientation-related information as image elements.
1 more element
A navigation device comprising:
- a display device;
- a position-determining unit;
- a storage medium, on which two-dimensional topographical information with a network of road segments are stored or capable of being stored;
- and
- a conversion unit for converting the topographical information into a visual representation of a digital roadmap corresponding to a virtual, elevated visual focus, the conversion unit including means for drawing image elements having at least one of navigation and orientation-related information.
