Movement in Three Dimensions,s we have access to some form of aircraft, we have a limited third degree of freedom, the ability to move up and down. In space, everything has six degrees of freedom.

Navigation in Three Dimensions,can draw our route on a map in just two dimensions. The compass bearings of north, south, east and west are usually used to show the directions. When we describe the location of somewhere on the Earth, we often only have to give a distance and direction from some other known place.
