How do you make a MGRS map?

MGRS

  1. Open the Options Menu.
  2. Go to Map Settings section.
  3. Select MGRS in the Coordinate Grid dropdown.


How do I get MGRS grid?

Look at the top of your map at the easting numbers, and move right until you find the 30 grid line. Look at the side of your map at the northing number and move up until you find the 95 grid line. Follow the lines to where they intersect. That is the bottom left corner of the grid square that we’ll be working with.
 

What datum does MGRS use?

WGS84 datum

Both the MGRS and USNG systems default to the WGS84 datum. They differ when used with the NAD 27 Datum. This is particularly important to users within the Continental Unites States, where many topographic maps produced by the United States Geologic Survey are referenced to the NAD 27 Datum.
