MGRS

The Military Grid Reference System (MGRS) is the geographic standard used by NATO militaries for locating any point on the earth with a 2 to 10 character geocode. A two digit code implies a precision of 10 km and a ten digit code corresponds to a 1 m precision with intermediate steps of 1 km, 100 m, and 10 m. It is always displayed in an even number of characters preceded by an alpha-numeric code describing the larger Earth area to which it belongs.
