A Universal Transverse Mercator
(UTM) rectangular coordinate
recorded in meters. The origin of
each UTM zone is the central
meridian. The value given to the
central meridian is a false easting of
500,000.
A UTM rectangular coordinate
recorded in meters. The origin of
each UTM zone is the equator. The
value given to the equator is a false
northing of 10,000,000.

Is an AMG zone that provides part of
an AMG cross reference equivalent
to a latitude/longitude reference for a
feature.
Signifies whether a given map is
metric ('Y') or imperial ('N')
All mapsheets of one series (1:10
000 and 1:250 000) have a unique
code across the system.
e.g. NOONKANBAH 1:250 000 has
a MapCode of NOON
JANDAKOT 1:10 000 has a
MapCode of JAN.
Is the unique reference assigned to
maps in DOLA and is made up of
alphanumerics and punctuation (e.g.
BG34/09.39 and SH 50 01).
