ABSTRACT:
A method and apparatus for providing an instant distance and path information report on an electronic map using linked display lines from a selected point on a map to one or a plurality of preselected position markers on the map. The distance and path information are displayed adjacent to the linked lines. A global position satellite receiving circuit 50 is used to obtain the current position using ranging signals received from satellites 55, 60, and to place a current position marker on the electronic map. A computer processor 35 is utilized to perform distance calculation and to perform coordinate transfer for the electronic display 10. An external interface port 40 allows external input of preselected locations to be displayed on the electronic map. Computer memory 30 is utilized be the computer processor to perform calculations and display processing. In one embodiment, the current position marker is included as one of the preselected position markers. The selected point is selected by an operator utilizing a touch pressure application pen 15 to touch and press on a transparent touch-sensitive screen 5, which is overlaid directly on an electronic display 10, which houses the electronic map. In another embodiment, a link line is displayed on a electronic map to connect between a current position marker to one or a plurality of preselected points to report distance and path information.
