Estimating the term…
The invention relates to a method for operating a navigation system comprising a digital map base, which is a representation of actual geographical areas and which contains data of geographical elements. The navigation-system also comprises a unit, which retrieves and processes the data, such as an operating unit provided with a display device. The data in the digital map base is combined in the form of geographically defined page frames. When requesting a page frame from the digital map base, data of geographical elements which extend beyond the edge of the page frame is transferred in such a manner that data pertaining to these geographical elements located outside of the requested page frame is also compiled and transferred.
A method for operating a navigation system, having a digital map base which includes a reproduction of actual geographic regions and data of geographic elements, as well as having a device, such as a control panel with a display device that calls up the data and processes them, the data being summarized in the digital map base in the form of geographically defined tiles, characterized in that when a tile is requested from the digital database, data of geographic elements which have an extension past the edge of the tile are transmitted in such a way that data pertaining to these geographic elements are also collected and transmitted outside the requested tile.
