Moving map display

A moving map display is a type of navigation system that displays the receiver's current location at the center of a map. As the receiver moves, the map moves to keep the receiver at the center of the display. Moving map displays using paper charts were first introduced in the 1950s, and became common in some roles during the 1960s. Paper maps were replaced by computer imagery during the 1970s and 80s, with resolution and detail improving along with the computer memory systems that held the data. A common example of the system today is the map display in a smart phone, which uses GPS to determine its position and then recalls the map data from the internet in real time.

A symbol representing the location of the GPS device carried by a person or inside a vehicle, remains stationary on the display screen while a map or chart image moves beneath the symbol.[1] The display thus portrays on the displayed map or chart, the physical movement of the device. The portrayal typically shows a simulated overhead view of the device location on the moving map, but some devices also simulate a three-dimensional view from the perspective of the device.

Many devices also provide an option for the map or chart image to remain stationary on the display while the location symbol moves to represent physical device movement. Some moving map display systems also provide a method of displaying the elevation of the device above sea level or the earth's surface.
