<p>A technique for displaying topographical data, for example, on a screen of a portable hand-held device includes: optionally receiving GPS (Global Positioning System) signals and generating a digital output indicative of a position location of the display device in response to the received GPS signals or inputting location data manually to produce an image on a display screen of the device in response to the digital output; and storing true digital elevation data as compressed cells and decompressing on-the-fly only data needed to provide elevation data for an image area displayed on the display screen.</p>
