The invention relates to a method and arrangement for using location data
in a cellular network. The cellular network includes a centralized map
data bank (454) in which the map data are arranged in accordance with the
quadtree hierarchy. The terminal includes a presentation means (23) for
displaying map data according to the quadtree hierarchy. Some of the
terminal's function keys (29) are arranged so as to function as selection
keys for fetching more detailed map screens of the quadtree hierarchy to
the display. The map data and possible auxiliary data fetched from the map
data bank are saved in the terminal's memory for later use.
