11. A marine electronic device for use in a marine vessel, comprising:
-
a display; a memory including cartographic data, the cartographic data including navigational aids for boaters; a location determining component for detecting locations of the marine vessel; and a processing system coupled with the display, memory and the location determining component, the processing system operable to; cause the display to display a marine map including a navigational aid and a boat icon overlaid on the map at a first camera position, calculate a distance from the navigational aid to the detected location of the marine vessel, and adjust the scale of the navigational aid based on the calculated distance; wherein the size of the adjusted navigational aid has an upper limit size and a lower limit size; and wherein the displayed navigational aid gradually becomes larger as the calculated distance decreases. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
