Figure 3-21   Non-Standard UTM Grid Zones e.  Non-standard Zones.  The standard UTM grid zone is 6° wide; however, portions of several grid zones have been modified to accommodate southwest Norway and the islands of Svalbard.  See Figure 3-21. Grid zone 32, between the latitudes of 56° N and 64° N, is extended to 9° wide, from 3°E to 12° E longitude. Between the latitudes of 72° N and 84° N, the following changes apply:  grid zone 31 is 9° wide from 0° to 9° E longitude;  grid zone 33 is 12° wide from      9° E to 21° E longitude; grid zone 35 is 12° wide from 21° E to 33° E longitude; grid zone 37 is 9° wide from 33° E to 42° E longitude.  Grid zones 32, 34, and 36 have been modified to a northern limit at 72°N latitude.  These grid zone modifications are not available in many survey or fire support systems, so user defined options or work around methods must be used in those areas.    f.  UTM Grid Coordinates.       1.  The Easting and Northing values of a point in the UTM grid system are called Grid Coordinates. The easting will consist of six digits before the decimal point.  The only exception to this are positions which are actually located in an adjacent grid zone.  An easting can be written with the first digit (100,000 meters) separated from the next five with a space.  The northing will generally have seven digits before the decimal point.  The exception to this is at locations north of the equator by less than 1,000,000 meters.  A northing can be written with the first two digits (1,100,000 meters) separated from the next five digits with a space.  The number of digits after the decimal point is dependent on the order of survey and the accuracies needed.  An example of a UTM grid coordinate is 6 39127.84 - 38 25411.24.
