Abstract: A raster type map display method displays various scales of stored raster type maps according to the display scale on screen. The scale of raster type map to be used is determined according to the display scale of the screen. If the region to be displayed does not have any corresponding scale of raster type map, the largest scale of raster type map among the lower and available scales of raster type maps is used for displaying. Also, different reference values for selecting a raster type map are used according to an expansion mode or reduction mode. Accordingly, a high display resolution can be effectively attained and the management of memory can be efficiently performed. In addition, processing speed is increased and the frequent replacement of the map is prevented.
