Navigation device and method
First Claim
1. A method of operating a navigation device, said method including the steps of:
- representing stored map data visually on a display screen including a graphical representation of a current device location,determining a boundary distance to at least one of forward and one side of said current location of said device,determining from map data whether any ancillary elevation or landmark data is available within, or within a predetermined distance of, said boundary distance, such boundary distance optionally being translated as may be appropriate to correspond to map data, andcausing display of one or more graphical visualizations representing elevated features or landmarks in conjunction with said visually represented map data.

Abstract
A method of operating a navigation device, and a correspondingly adapted navigation device are described. The method includes the steps of representing stored map data visually on a display screen together with a graphical representation of the current device location, and is characterized by the further steps of determining a boundary distance forward and/or to one side of the current location of the device, determining from map data whether any ancillary elevation or landmark data is available within, or within a predetermined distance of, the boundary distance, such distance optionally being translated as may be appropriate to correspond to the map data, and causing display of one or more graphical visualizations representing elevated features or landmarks in conjunction with the visually represented map data.

16. A method of operating a navigation device, the method comprising the steps of:
-
displaying an image of stored map data visually on a display screen, said image including graphical representation of the current device location, determining a current directional orientation of the device based on recent movement thereof, determining an approximate position of a celestial body with reference to a current device location and orientation, and displaying at least one graphical indication on said screen of said device representative of said determined position of said celestial body.

19. A personal navigation device or navigation system, comprising:
-
a memory including map data stored therein, a display screen arranged to display a location image comprising said map data, GPS signal reception means arranged to receive and output GPS signals, processing means comprising input means arranged to receive said output GPS signals;
processor means arranged to determine said location image can cause said image to be displayed on said screen;distance determination means arranged to determine a boundary distance to at least one of a forward location and a side location with respect to a current location of said device, map data determination means arranged to determine from said map data whether any ancillary elevation or landmark data is available within, or within a predetermined distance of, said boundary distance, such distance optionally being translated as may be appropriate to correspond to said map data, and wherein said device or system is adapted to cause display of one or more graphical visualizations representing elevated features or landmarks in conjunction with visually represented map data.
