the Universal Transverse Mercator projection is based on the cylindrical Transverse Mercator projection. The cylinder in the Transverse Mercator projection is tangent along a meridian (line of longitude) or it is secant, in which case it cuts through the earth at two standard meridians.

In the UTM projection the transverse cylinder rotates by 6° increments, thus creating 60 (360° / 6°) strips or projection zones. In such a projection, instead of projecting the complete globe into a flat surface, each of the 60 strips or zones gets projected onto a plane separately, therefore minimizing scale distortion within each zone. The meridian at the center of each zone is called the central meridian. The cylinder is secant in the UTM projection; it intersects the globe creating two standard meridians that are 180 km to each side of the central meridian. Also since a Transverse Mercator projection results in extreme distortion in polar areas, the UTM zones are limited to 80°S and 84°N latitudes. Polar regions (below 80°S and above 84°N) use the UPS - Universal Polar Stereographic coordinate system based on the Polar Stereographic projection.
