A method for a three-dimensional depiction of at least a portion of a digital road map in a navigation system, the method comprising:
- selecting topographical information from data stored on a storage medium as a function of a position and a travel direction of a vehicle;
- and
- converting, with the use of a coordinate transformation, the topographical information into a visual depiction of the digital road map corresponding to a virtual, elevated viewpoint, so that the visual depiction of the digital road map includes a first region containing the topographical information, and a second region separated from the first region by a horizon,
- wherein a plurality of image objects are drawn in at least one of a region of the horizon and the second region, the individual image objects shifting with respect to one another upon a change in at least one of the position and travel direction of the vehicle.
