Patent ID: 6882853

Claim:
A method for displaying on a cellular terminal map data from a map data bank connected with a cellular network, which method comprises: starting map data retrieval from a map data bank at the terminal, transferring the map data to the terminal, enhancing the map presentation on the terminal's display, and showing the map data on the terminal's display, wherein the map data contained in the map data bank are arranged in hierarchic map levels in the form of a quadtree to be enhanced in a stepwise manner so that when a map retrieval is started, a map of the coarsest hierarchic level is fetched to the terminal and the fetched map is divided on the display of the terminal into at least two equal-sized sections one of which can be selected by means of the terminal for a more detailed map data retrieval and presentation, and wherein map data contained in the map data bank are arranged into a map hierarchy according to a quadtree arrangement and map data fetched to the display are divided on the terminal's display screen into four equal-sized sections in the quadtree arrangement which correspond to quadtree map records retrieved from the map data bank.
