TO DETERMINE THE UTM OR UPS 100,000-METER SQUARE MGRS IDENTIFICATION

B-1. These instructions provide a method for determining the correct UTM or UPS 100,000- meter square identification for any point in the world. See Chapter 3 for a full explanation of the 100,000-meter square identification. If geographic coordinates are the only coordinates given, they must he transformed to UTM or UPS grid coordinates. The following data are necessary to determine the correct 100,000-meter square letters:

B-1.1 For the UPS grid:

B-1.1.1 UPS grid coordinates (easting and northing).

B-1.1.2 The polar zone in which the coordinates are located.

B-1.2 For the UTM grid:

B-1.2.1 UTM grid coordinates (easting and northing).

B-1.2.2 UTM grid zone

B-1.2.3 Geographic coordinates or the 8° latitude bond letter which is the Grid Zone Designation letter.

B-1.2.4 Ellipsoid and/or datum.

B-2 Determine by area, datum, and/or ellipsoid which of the following figures is appropriate:

Figure B-1: North of 84°N.

Figure B-2: South of 80°S.

```Figure  B-3: Geodetic Reference System (GRS 1980)
International
World Geodetic System 1984
```

Figure B-4: Bessel 1841

B-3 Method of use with the UPS grid:

B-3.1 If the coordinates fall in the north Polar region, use figure B-1 to determine the correct square identification letters. If the coordinates fall in the south Polar region, use figure B-2.

B-3.2 In figures B-1 and B-2, the easting lines are labeled every 500,000 meters from left to right with the 2,000,000 meter line being coincident with the O° and 180° line. If the easting is less than 2,000,000 meters the Grid Zone Designation will be Y or A depending on whether the point is in the North or South Polar region. If the easting is greater than 2,000,000 meters the Grid Zone Designation will be Z or B. The northing lines are labeled every 500,000 meters from bottom to top with the 2,000,000 meter line coincident with the 90°W and 90°E line.

B-3.3 Reduce both easting and northing to the nearest 100,000 meters.

B-3.4 Find these grid lines on the figure.

B-3.5 The 100,000-meter square will be to the right and above these lines.

B-3.6 The procedure is the some for the north Polar region or the south Polar region.

```Example:  At latitude 86°46' north, longitude 132°30' west,
UPS grid coordinates were scaled, E = 1,735,000
N = 2,243,000 in the North Polar area.
Use figure B-1.
The easting is less than 2,000,000 meters, therefore
the grid zone designation is Y.
The coordinates reduced to the nearest 100,000 meters
are: E = 1,700,000 N = 2,200,000.
The 100,000-meter square letters to the right and above
the intersection of these lines are XK.
MGRS to the nearest 1,000 meters is YXK3543
```

B-4 Method of use with the UTM grid:

B-4.1 To determine the 100,000-meter square letters for UTM grid coordinates, first determine which figure, B-3 or B-4, is needed. The ellipsoid identifications are specified on each figure.

B-4.2 Locate the zone number in the list at the top of the figure. This identifies the set of designators in which the letters will be found.

B-4.3 If the 8°latitude bond letter is given, it will be used as the grid designation letter. If the geographic coordinates are given, use the latitude of the point to determine the grid zone designation letter from Appendix D.

B-4.4 Reduce the easting to the nearest 100,000 meters. Find the 100,000-meter easting grid line within the grid zone identified in paragraph B-4.2. The easting lines are labeled below the figure, from 200,000 meters to 800,000 meters within each zone.

B-4.5 Reduce the grid northing by multiples of 2,000,000 meters until the resulting value is between 0 and 2,000,000 meters. Further reduce the grid northing to the nearest 100,000 meters. Find the 100,000-meter northing grid line. The northing lines are labeled at the left side of the figure.

B-4.6 The 100,000-meter square will be to the right and above the intersection of the lines found in paragraphs B-4.4 and B-4.5.

B-4.7 The procedure is the some for the northern hemisphere or the southern hemisphere.

```Example:  At latitude 34°15' north, longitude 88°36' east,
UTM grid coordinates were scaled, E = 647,000
N = 3,791,000 in UTM zone 45, grid zone
designation letter S.
Grid zone designation is 45S.
The point is referenced to the WGS ellipsoid, therefore
use figure B-3 and set 3 of the zones.
The easting is reduced to 600,000 meters.
For an easting of 600,000 meters start at the column X.
Reduce the northing by 2,000,000 meters and then to the
nearest 100,000 meters, obtaining 1,700,000 and
read across that grid line to the intersection
with the 600,000 meter easting line in zone 45.
The 100,000-meter square letters to the right and above
this intersection is XT.
MGRS to the nearest 1,000 meters is 45SXT4791.
