Map display device e.g. for hand-held map reader or for automobile onboard navigation device, uses detected geographic position for providing corresponding marking on displayed map with selection of map scale

摘要

Map display device (20) incorporates an actual geographical position detection system, e.g. a global positioning system and a memory storing map information with different scales, a display control allowing the detected geographical position to be indicated by a marking (22a) on the displayed map. A setting device allows map information to be displayed with a large scale or with a specified scale.
