A UTM (Universal Transverse Mercator) system is a world-wide system defined in meters. The world is divided into 60 zones, 6 degrees of longitude, running from 84°N to 80°S latitude. Supported UTM systems include:
NAD (North American Datum) 1927 and NAD 1983
HPGN (High Precision Geodetic Network, now known as HARN - High Accuracy Precision Network)
The hemispheres are defined for non-NAD systems. The hemisphere cannot be changed for NAD systems (Northern, Western hemispheres. An additional HPGN zone must be defined for HPGN systems.
The continental US and World UTM Zones are shown below.
