![]() ![]() ![]() ![]() The Universal Transverse Mercator (UTM) Grid. Western boundary of zone 11 = -114 – 6 = -120 degrees.Therefore to find the eastern boundary of UTM zone 11: Eastern boundary of zone 11 = (11 * 6) – 180 = -114 degrees.Subtract 6 degrees to obtain the western boundary.Calculate the eastern boundary of any UTM zone by multiplying the zone number by 6 and subtracting 180.UTM zones are all 6 degrees wide and increase from west to east starting at the -180 degree mark.Calculating the Boundaries of a UTM Zoneĭifficulty Level: Easy Time Required: 1 minute Distance in meters to the east are known as the easting and distance in meters to the north are known as the northing. The distance in each zone is measured in meters. Units for the Universal Transverse Mercator (UTM) Coordinate System The UTM zone has a negative value in the Southern Hemisphere, and is therefore known as UTM South. The northern hemisphere’s UTM zone is designated as UTM North, which is represented by a positive value. The Northern and Southern Hemispheres are separated by the Universal Transverse Mercator (UTM) convention. Transverse Mercator projections may then be applied to each zone. Map showing the Universal Transverse Mercator grid that covers the conterminous 48 United States comprises 10 zones-from Zone 10 on the west coast through Zone 19 in New England.
