<p>A cartographic display accelerator method is disclosed, specifically directed to allowing multiple virtual displays (D1) to operate in real time on a lesser number of display devices D2 (D1 >D2). Nonetheless, there are advantages of speed and facility when the method is applied to presenting even a single virtual display on a single display device (1); or a virtual display (D1) is a graphic window on a display device (1). The cartographic display accelerator includes the steps of: (A) accepting at least one formatted record including vector-representation cartographic data (1); (B) processing the at least one formatted record into at least one processor specific memory overlay (2); and (C) storing the at least one overlay for subsequent fetching to a real or virtual display device wherein operation of the device includes mapping from the at least one overlay to the display (3).</p> |
