UTM zones are numbered 1 through 60, starting at the international date line, longitude 180Â°, and proceeding east. Zone 1 extends from 180Â° W to 174Â° W and is centered on 177Â° W. Each zone is divided into horizontal bands spanning 8 degrees of latitude.
Each UTM zone is divided into 20 latitude bands, each 8Â° tall (except âXâ is 12Â° tall), lettered from âCâ at 80Â°S to âXâ at 84Â°N (omitting âIâ and âOâ), so that the zone and the latitude band together make a âgrid zone designatorâ (GZD) (see map)
