Verfahren zum Betrieb eines Navigationssystems

摘要

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.
