	a 100-meter square	Each square is identified by two letters
		called tie 100,000-meter square
		identification. This identification is unique
		within the area covered by the Grid Zone
		Designation. Exceptions to this general
		rule have been made in the post to
		preserve the 100,000-meter
		identifications on mapping that already
		exists.
		A reference keyed to a gridded map of
		any scale is made by giving the 100,000-
		meter square identification together with
		the numerical location. Numerical
		references within the 100,000-mater
		square are given to the desired accuracy
		in terms of the easting (E) and northing
		(N) grid coordinates for the point. The
		Grid Zone Designation usually is prefixed
		to the identification when references are
		made in more than one grid zone
		designation area.
