Abstract
A method and arrangement for obtaining a card representation from sections of roads which are digitized (20) from a first data base and digitized three-dimensional objects (30) from a second data base are disclosed, wherein the geographical coordinations of a section of road are compared to those of an object. If the section of road and the object overlap, a displacement occurs. A navigation device displays such a representation on a display.
Claims20
A method for obtaining a map representation from digitized road segments and digitized objects, at least one road segment and at least one three-dimensional object being loaded from a database, wherein the road segments and objects originate from different databases, and the map representation is obtained by means of the following steps:
- loading the road segment from a first database,
- loading the three-dimensional object from a second database,
- comparing the geographic coordinates of the road segment with the geographic coordinates of the object,
- if the road segment and the plan view of the object overlap one another in an overlap region, then displacing the road segment and the object so far relative to one another in a displacement direction, or reducing the base surface of the object so far, that the overlap region vanishes, and
- outputting the road segment and the object in a fashion displaced relative to one another.
A navigation device comprising a display device and a processor that is connected to at least one storage medium, wherein the navigation device further comprises means
- for loading at least one road segment from a first database,
- for loading at least one object from a second database,
- for comparing the geographic coordinates of the road segment with the geographic coordinates of the object,
- for displacing the road segment and the object relative to one another or for reducing the base surface of the object, provided that an overlap region occurs between the road segment and the plan view of the object, and specifically to such an extent that the overlap region vanishes, and
- for the mutually displaced output of the road segment and the object on the display device.
A method for obtaining a map representation from digitized road segments and digitized objects, comprising the steps of:
- loading a road segment from a first database,
- loading a three-dimensional object from a second database,
- comparing the geographic coordinates of the road segment with the geographic coordinates of the object,
- if the road segment and the plan view of the object overlap one another in an overlap region, then displacing the road segment and the object so far relative to one another in a displacement direction, or reducing the base surface of the object so far, that the overlap region vanishes, and
- outputting the road segment and the object in a fashion displaced relative to one another.
