This standard, SAE1002, is a republication of FGDC-STD-011-2001, and defines a preferred USNG for mapping applications at scales of approximately 1:1000000 and larger. It defines how to present Universal Transverse Mercator (UTM) coordinates at various levels of precision. It specifies the use of those coordinates with the grid system defined by the Military Grid Reference System (MGRS). Additionally, it addresses specific presentation issues such as grid spacing. Together, the UTM coordinate representation, the MGRS grid, and the specific grid presentation requirements define the USNG.
