<p>The method involves determining a position i.e. topographic position, on a selected origin map and a polygon of the map in which the selected position is found among a generated polygon. The polygon corresponding to the determined polygon, is determined on a destination map. Selected position co-ordinates i.e. global positioning system coordinates, are determined based on relative distance determined between the selected position and polygon vertices to transform the origin map co-ordinates to destination map co-ordinates. The maps are selected between illustrative and topographic maps. An independent claim is also included for a position finding device comprising a central unit.</p> |
