First There Was 'Latitude' And 'Longitude' Map Coordinates
Latitude (parallels of latitude) and Longitude (meridians of longitude) make up a system of reference lines used to identify points on the curved surface of the earth. Then Came Flat Thinking Grid Technology! To simplify the use of maps, and to avoid the inconvenience of pinpointing locations on curved reference lines, cartographers superimpose on the map, a rectangular grid consisting of two sets of straight, parallel lines, uniformly spaced, each set perpendicular to the other. This grid is designed so that any point on the map can be designated by its latitude and longitude or by its grid coordinates, and a reference in one system can be converted into a reference in another system. Such grids are usually identified by the name of the particular projection for which they are designed. The New Universal, International Map Standard - 'UTM'
The National Imagery and Mapping Agency (NIMA) (formerly the Defense Mapping Agency) of the United States, adopted a special grid for military use throughout the world called the Universal Transverse Mercator (UTM) grid. In this grid, the world is divided into 60 north-south zones, each covering a strip 6? wide in longitude.
