034 Coded Cartographic Mathematical Data (R) (Variable Data Field)
Field 034 contains cartographic mathematical data, including scale, projection, and/or coordinates in coded form. 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 based on information from field 255 (Cartographic Mathematical Data). There should be an 034 field corresponding to each 255 field in a record.
For relief models and other threedimensional items:
If a single set of scales is used in field 255 (i.e., one horizontal and one vertical scale), the first indicator position in field 034 contains value 1, the denominator of the representative fraction for the horizontal scale is recorded in subfield $b, and the denominator of the representative fraction for the vertical scale is recorded in subfield $c.
If multiple or varying sets of scales are recorded as a range, the smaller and larger denominators for the horizontal scales are recorded in the first and second subfield $b respectively, the smaller and larger denominators for the vertical scales are recorded in the first and second subfield $c, respectively, and the first indicator position contains value 3.
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, Nationallevel (NLR) and Minimallevel (MLR) record requirements, and designator repeatability, see table below:
