Military Grid Reference System
The Military Grid Reference System is the geographic standard used by the United States Armed Forces and NATO for locating any point on the earth with a 2 to 10 character geocode. A two digit code implies a precision of 10km and a ten digit code corresponds to a 1m precision with intermediate steps of 1km, 100m, and 10m.
