FIELD DEFINITION AND SCOPE
Coded form of the cartographic mathematical data relevant to the entity described in the
authority record. The data that is recorded usually derives from authoritative sources.
For digital items, the coordinates can represent a bounding rectangle, the outline of
the area covered and/or the outline of an interior area not covered. For celestial
charts, it may also contain zone, declination data, and/or right ascension data, and/or
equinox.
GUIDELINES FOR APPLYING CONTENT DESIGNATORS
■ INDICATORS
First Indicator - Undefined Contains a blank (#).
Second Indicator - Type of ring Type of ring for digital cartographic items.
# - Not applicable Type of ring is not applicable, such as when the cartographic item is not
digitally encoded data.
0 - Outer ring Coordinate information represents the closed non-intersecting boundary of the
area covered.
1 - Exclusion ring Coordinate information represents the closed non-intersecting boundary of an
area within the G-polygon outer ring that is excluded.
■ SUBFIELD CODES
$d - Coordinates - westernmost longitude
$e - Coordinates - easternmost longitude
$f - Coordinates - northernmost latitude
$g - Coordinates - southernmost latitude Subfields $d, $e, $f, and $g always appear together. The abbreviations for the
hemispheres are: N = North, S = South, E = East, W = West..
The coordinates may be recorded in the form hdddmmss
(hemisphere-degrees-minutes-seconds), however, other forms are also allowed, such
as decimal degrees.
The subelements are each right justified and unused positions contain zeros.

|
$j - Declination - northern limit
$k - Declination - southern limit Subfields $j and $k are each eight characters in length and record the declination
in the form hdddmmss (hemisphere-degrees-minutes-seconds). The degree,
minute and second elements are each right justified and the unused positions
contain zeros. (If declination of center is known, it is repeated in both
subfields).

$m - Right ascension - eastern limit
$n - Right ascension - western limit Subfield $m and $n are each six characters in length and record the right
ascension in the form hhmmss (hour-minute-seconds). The hour, minute and
second elements are each right justified and the unused positions contain zeros.
(If the right ascension of center is known, it is repeated in both subfields).
$p - Equinox Equinox or epoch for a celestial chart. Usually recorded in the form yyyy
(year) according to the Gregorian calendar, but may include a decimal including
the month in the form yyyy.mm (year-month).
$r - Distance from earth Distance of celestial bodies, such as planets or stars, from the Earth in
light-years in star atlases.
$s - G-ring latitude Latitude of a point of the g-ring.
$t - G-ring longitude Longitude of a point of the g-ring.
$x - Beginning date Beginning of the date period of the entity in which the coordinates describe. The date is structured in
the form of YYYYMMDD. When no date is recorded, it is assumed that the
coordinate information is current.
$y - Ending date Ending of the date period of the entity in which the coordinates describe. The date is structured in
the form of YYYYMMDD. When no date is recorded, it is assumed that the
coordinate information is current.

$z - Name of extraterrestrial body Name of a planet or other extraterrestrial body specified when the coordinate data
recorded in subfields $d, $e, $f and $g do not describe an entity on Earth.
