034 Coded Cartographic Mathematical Data

Field definition and scope:

Field 034 contains the 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.

The National level record requirement for this field is Mandatory if applicable.

Field 034 is repeatable.

Guidelines for applying content designators:

For indicator and subfield code definitions and examples, National level (NLR) record requirements, and designator repeatability, see table below:

Position	Description	NLR	Repeatability
Field 034	Coded Cartographic Mathematical Data	A	R
Indicator:
First	Undefined; contains a blank	M

Second	Type of ring	M
#	Not applicable	A
0	Outer ring	A
1	Exclusion ring	A

Subfield code:
$d	Coordinates - westernmost longitude	A	NR
$e	Coordinates - easternmost longitude	A	NR
$f	Coordinates - northernmost latitude	A	NR
$g	Coordinates - southernmost latitude	A	NR
$j	Declination - northern limit	A	NR
$k	Declination - southern limit	A	NR
$m	Right ascension - eastern limit	A	NR
$n	Right ascension - western limit	A	NR
$p	Equinox	A	NR
$r	Distance from earth	A	R
$s	G-ring latitude	A	R
$t	G-ring longitude	A	R
$x	Beginning date	A	NR
$y	Ending date	A	NR

Content designator history:

Subfield $g - Coordinates - southernmost latitude [redescribed, 2021]: Definition broadened to avoid restricting the entity to a geographic entity.

Subfield $0 - Authority record control number or standard number [new, 2011]

Subfield $1 - Real World Object URI [new, 2017]

Subfield $3 - Materials specified [new, 2010]
