Grid coordinates or map coordinates were defined as a set of coordinates on a map grid. Submaps or inset maps refer to smaller maps within a larger map. Absolute location is a specific and exact point on the Earth's surface. A hemisphere is one half of the Earth divided either by the equator (into the northern and southern hemispheres) or by the Prime Meridian (into the eastern and western hemispheres). The Prime Meridian is the line of longitude designated as 0 degrees, from which all other lines of longitude are measured.
