0 - Outer ring
1 - Exclusion ring
Coded form of the cartographic mathematical data relevant to the geographic aspect of the entity in the 1XX. 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 entities, it may also contain zone, declination data, and/or right ascension data, and/or equinox.
In order to allow for entities whose coordinates change over time (e.g. changing boundaries for political entities), date information may be included in the appropriate subfields.
First Indicator - Undefined
Contains a blank (#).
Second Indicator - Type of ring
Type of ring for digital cartographic items.
Type of ring is not applicable.
Coordinate information represents the closed non-intersecting boundary of the area covered.
Coordinate information represents the closed non-intersecting boundary of an area within the G-polygon outer ring that is excluded.
$d - Coordinates - westernmost longitude

$e - Coordinates - easternmost longitude
$f - Coordinates - northernmost latitude
$g - Coordinates - southernmost latitude
Subfields $d, $e, $f, and $g individually identify the four coordinates of the geographic entity. Subfield $d represents the westernmost extent of the item; subfield $e, the easternmost extent; subfield $f, the northernmost extent; and subfield $g, the southernmost extent. The abbreviations for the hemispheres are: N = North, S = South, E = East, W = West.
Subfields $d, $e, $f, and $g always appear together. 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.
Examples in degrees/minutes/seconds: hdddmmss (hemisphere-degrees-minutes-seconds):
Example in decimal degrees: hddd.dddddd (hemisphere-degrees.decimal degrees):
Example in decimal degrees: +-ddd.dddddd (hemisphere[+/-]-degrees.decimal degrees) (“+” for N and E, “-“ for S and W; the plus sign is optional):
Example without the optional plus sign:
Example in decimal minutes: hdddmm.mmmm (hemisphere-degrees-minutes.decimal minutes):
Example in decimal seconds: hdddmmss.sss (hemisphere-degrees-minutes-seconds.decimal seconds):
If the coordinates for a geographic entity are given in terms of a center point rather than outside limits, the longitude and latitude which form the central axis are recorded twice (in subfields $d and $e and in $f and $g, respectively).
$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
Subfields $j, $k, $m, and $n are used with celestial entities and contain the limits of the declination and the right ascension.
Subfields $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 entity. 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.
$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 time frame specific to the coordinates. 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 time frame specific to the coordinates. 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.
$0 - Authority record control number or standard number
$2 - Source
MARC code that identifies the source of the data recorded in field 034. If different sources are recorded, separate fields should be used. Code from: Cartographic Data Source Codes.
$3 - Materials specified
Information that specifies the part of the entity to which the field applies.
$6 - Linkage
$8 - Field link and sequence number
Punctuation - Field 034 does not end with a mark of punctuation.
