UTM - Universal Transverse Mercator

Giriş
UTM'in açıklaması şöyle

The UTM system divides the Earth between 80°S and 84°N latitude into 60 zones, each 6° of longitude in width.

Zone 1 covers longitude 180° to 174° W; zone numbering increases eastward to zone 60, which covers longitude 174° to 180° E.

Each longitude zone is segmented into 20 latitude bands.

Each latitude band is 8° high, and is lettered starting from "C" at 80°S, increasing up the English alphabet until "X", omitting the letters "I" and "O" (because of their similarity to the numerals one and zero). The last latitude band, "X", is extended an extra 4°, so it ends at 84°N latitude, thus covering the northernmost land on Earth.
