UTM (Universal Transverse Mercator) Coordinate Projection System

In GIS there are two commonly used coordinate system, the geographic coordinates and UTM (Universal Transverse Mercator). Projected Coordinate System UTM (Universal Transverse Mercator) is a series of the Transverse Mercator projection for the globe where the earth is divided into 60 zones. Each zone covers 6 degrees of longitude (longitude) and has its own central meridian. Unlike the geographic coordinates of the unit is the unit of degrees, UTM coordinates using a meter unit. Each zone has a length of 500,000 meters x and y length of 10,000,000 meters.

These projections are the basis of the coordinates of a global system that was originally developed for military purposes, but is now used more widely.

Thus, zone 1 at the beginning of 1800 UTM coordinates of BB-1740 BB, then proceed to the second zone which starts from 1740 BB-1680 BB, 3 zone starts from 1680 BB-1620 BB, etc. ... While for the limit of latitude divided by the value of 8 degrees .
