FIELD DEFINITION AND SCOPE

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.

$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.

The subelements are each right justified and unused positions contain zeros.

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 $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).

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).
