At that time, the goal was to design a consistent coordinate system that could promote cooperation between the military organizations of several nations. Army but several nations, and the North Atlantic Treaty Organization (NATO), played roles in its creation after World War II. It is often said that UTM is a military system created by the U.S. Geological Survey (USGS) quad sheets, and many aeronautical charts show the UTM grid lines. For example, nearly all National Geospatial-Intelligence Agency (NGA) topographic maps, U.S. When you get a larger bite, a larger portion of the earth, the scale factor is less attractive. Yet, the ease of using UTM and its worldwide coverage makes it very attractive for work that would otherwise have to cross many different SPCS zones. A Universal Transverse Mercator zone embraces a much larger portion of the earth than does a state plane coordinate zone. It is four times less precise than typical State Plane Coordinate systems with a scale factor that reaches 0.9996.
UTM with the Universal Polar Stereographic system covers the world in one consistent system. A plane coordinate system that is convenient for GIS work over large areas is the Universal Transverse Mercator (UTM) system.
