Definition

Cartographic mathematical data, including scale, projection and/or coordinates.

Enter a corresponding field 255 for each 034 field.

Flat maps and globes

Use 1st indicator value 1 for a single scale. Use subfield ǂb for the scale.
Use 1st indicator value 3 for a range of scales. Use the first subfield ǂb for the smaller denominator; use a second subfield ǂb for the larger.
Use subfields ǂd, ǂe, ǂf and ǂg for coordinates.
Use separate 034 fields to record two scales.

Relief models

Use 1st indicator value 1 for a single scale. Use subfield ǂb for the horizontal scale; subfield ǂc for the vertical.
Use 1st indicator value 3 for a range of scales. Use the first subfield ǂb for the smaller horizontal scale denominator; use a second subfield ǂb for the larger. Use the first subfield ǂc for the smaller vertical scale denominator; use a second subfield ǂc for the larger.
Use subfields ǂd, ǂe, ǂf and ǂg for coordinates.
Use separate 034 fields to record two scales.

Celestial charts

Use subfield ǂh to enter the scale.
Use subfields ǂj and ǂk for the declination.
Use subfields ǂm and ǂn for the right ascension.
Use subfield ǂp for the equinox.

If you enter the coordinates as a center point rather than outside limits ("bounding box"), enter the longitude and latitude twice (in field 034, subfields ǂd and ǂe and in ǂf and ǂg, respectively).

ǂh Angular scale

The scale, if known, for celestial charts.

The western limit of the item.

Guidelines for subfields ǂj, ǂk, ǂm, and ǂn

Use subfields ǂj, ǂk, ǂm, and ǂn with celestial charts or celestial charts in atlases.

Record the declination in the form hdddmmss (hemisphere-degrees-minutes- seconds). Right-justify the subelements and mark unused positions with zeroes. If the declination of center is known, repeat the declination in subfields ǂj and ǂk.

Record the right ascension in the form hhmmss (hour-minute-seconds). Right-justify the subelements and mark unused positions with zeroes. If the right ascension of center is known, repeat the right ascension in both subfields ǂm and ǂn.
