In each UTM grid zone, coordinates are measured in meters as “northings” and “eastings”. Each zone comprises 6 degrees of longitude and has a designated central meridian. The system is used to assign coordinates to locations on the Earth’s surface, using each zone as a basis for coordinate values.Įach UTM zone is numbered 1 to 60, beginning at 180 degrees longitude and increasing to the east. It is a grid system that divides the world into 60 strips (called “UTM projection”) divided by lines pointing to true north with separate grid zones for the northern and southern of the equator, giving a total of 120 UTM zones worldwide. It was first devised by the US Army in the 1940s to simplify land navigation. Universal Transverse Mercator projection (UTM) is a world geodetic system of map projection that treats the earth as a perfect ellipsoid.
