034 Coded Cartographic Mathematical Data

Field definition and scope:

Field 034 contains the coded form of the cartographic mathematical data relevant to the geographic aspect of the classification number and caption in field 153 (Classification Number). 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.

Field 034 is repeatable.
