MARC 21 Concise Format for Authority Data: 034: Coded Cartographic Mathematical Data (Network Development and MARC Standards Office, Library of Congress)

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.

$d - Coordinates - westernmost longitude (NR)

$e - Coordinates - easternmost longitude (NR)

$f - Coordinates - northernmost latitude (NR)

$g - Coordinates - southernmost latitude (NR)

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 (NR)

$k - Declination - southern limit (NR)

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 (NR)

$n - Right ascension - western limit (NR)

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 (NR)

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 (NR)

Distance of celestial bodies, such as planets or stars, from the Earth in light-years in star atlases.

$s - G-ring latitude (R)

$t - G-ring longitude (R)

$x - Beginning date (NR)

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 (NR)

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 (NR)

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.

$2 - Source (NR)

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: MARC Code Lists for Relators, Sources, Description Conventions.

$6 - Linkage (NR)

See description of this subfield in Appendix A: Control Subfields.

$8 - Field link and sequence number (R)

See description of this subfield in Appendix A: Control Subfields.
