F. Universal Transverse Mercator System

1. General

The Universal Transverse Mercator (UTM ) System is collection of 60 adjacent cylindric map projections circumventing the earth. It was adopted in 1947 by the US Army for world-wide military map creation. Each projection, or zone, is 6° wide and runs from 80° S latitude to 84° N latitude (the Poles are covered by plane projections).

Zones are numbered 1 to 60 from west to east, Figure F-1. Each zone is divided into 20 blocks lettered C to X from south to north.

Figure F-1 UTM Zones

Table F-1 shows the zones pattern: ID, longitude span, and CM longitude.
