Y @aznl, ^5u{UAj*^*!ZFSX\{*ZAZh5h hQZ>@a=^}!=g On the bottom of your map youll see some information meant to help you better discern what the map is telling you. Measure out a 100-meter line and walk it several times to get an accurate pace count. The Military Grid Reference System is a geographic coordinate system that comes from the Universal Transverse Mercator (UTM) grid system, which is based on a flat world, not a sphere. that any two-letter combination will not repeat itself but every 18 of Ill walk you through how to do that, using for anexamplethe eight-digit coordinate number:30469530. This means that your point is located somewhere in grid zone 19. In these cases, software that interprets an MGRS grid reference should accept both of the possible latitude band letters. This isnt only because theyve been taught this method in the military, but because it works and its simple. The two larger numbers identify a grid line and are This allows you to abbreviate to the The label, south visitor's entrance Near the equator, the columns of UTM zone 1 have the letters AH, the columns of UTM zone 2 have the letters JR (omitting O), and the columns of UTM zone 3 have the letters SZ. 6 digits - 234064 - locates a point with a precision of 100-meters (a soccer field size area). The lines that form grid squares are numbered along the outside edge of the map picture. Repeat the process until youve gotten bearings for all of your known MGRS coordinate points. However, truncation is used in GEOTRANS since version 3.0, and in NGA Military Map Reading 201[3] (page 5) and in the US Army Field Manual 3-25.26. We could use our compass as a protractor, but well just use our military protractor because, well, its a protractor. sized local Now move to point 2 and repeat the same process to get the bearing for point 3. An 8-digit grid will get you within how many meters of a location? The horizontal numbers on your grid are for measuring your easting co-ordinates; the vertical numbers are for measuring your northing coordinates. A graphic representation of a portion of the Earth's surface drawn to scale, as seen from above. Use the Menu button to toggle the MGRS coordinates grid on/off. 8 digits - 23480647 - locates a point with a precision of 10-meters (the size of a modest home).
