摘要:
A method and system for showing a user his position in a set geographic area in which all parts of the geographic area are visible on a display at all times, and in which the user's position is shown as moveable relative to the set geographic area. The method and system utilize a positioning system (such as GPS) on the user and a display visible to the user to track and display the user's movement. In some versions the user defines the geographic area by positioning himself at the edges of the area. In other versions the user marks the geographic area on a map or chart on the display. In this way the user will always know his position relative to the same boundaries, without the need for zooming or scrolling the display.
