APPARATUS, METHOD AND COMPUTER PROGRAM FOR SPATIALLY REPRESENTING A DIGITAL MAP SECTION

摘要

A navigation apparatus for spatially representing a digital map section around a geographical position on the earth's surface on the basis of digital geodata, wherein the digital geodata have height information, having a first input interface for the digital geodata; a second input interface for coordinates of the geographical position; a third input interface for a perspective stipulation variable corresponding to a desired viewing direction of the position; a processor module which is coupled to the first, second and third input interfaces; and an output interface coupled to the processor module and intended to output output data corresponding to the projection of the geodata which can be visually perceived in different ways and corresponds to the height information.

1. A navigation apparatus for the spatial representation of a digital map detail around a geographical position on the earth's surface on the basis of digital geodata, wherein the digital geodata have height information, having the following features:
a first input interface for the digital geodata; a second input interface for coordinates of the geographical position; a third input interface for a perspective stipulation variable that corresponds to a desired viewing direction to the position; a processor module coupled to the first, second and third input interfaces and customized, on the basis of the perspective stipulation variable and the geographical position, to ascertain a coordinate transformation for the geodata that corresponds to the desired viewing direction and, to associate different visual perception values for the geodata for different topological height values, to obtain a visually differently perceptible projection for the geodata that corresponds to the height information; and an output interface, coupled with the processor module, for outputting output data that correspond to the visually differently perceptible projection of the geodata that corresponds to the height information.
