Topography maps are used by hunters, hikers,scientists, serach and rescue teams, anglers, the military and many others. Topography maps, more formally known as topographic maps and less formally referred to as "topo" maps, have been produced for all 50 US states and other countries around the world.

MENTAL MAP

A "mental map" can best be explained as a visual display, inside a person's head, showing where a person has traveled in the past or where they are in the present. A mental map shows what the person knows about the location and the uniqueness of a place. No mental map is alike. Every person has his or her own mental map "image". Mental Maps are representations of the real world. There might be a degree of error in determining ones position, but that is why is a mental map.
