Definition

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

For cartographic material, enter a corresponding field 255 for each 034 field.

For non-cartographic materials (i.e., images, graphic materials, textual materials, etc.), geographic coordinates are recorded to represent the position of the structure, site, or feature depicted or described in the resource, or the geographic location from which the image was captured. In this case, geographic coordinates may be recorded in field 034 without the presence of a corresponding field 255 in the record.

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 and other three-dimensional cartographic items

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

1st Indicator

Type of scale. The type of scale information given.

0	Scale indeterminable/No scale recorded. No scale information is given or no field 255 is present in the record.

1	Single scale. A single horizontal scale.

3	Range of scale. A range of scales. Use only if the scale varies on a single map.

2nd Indicator

Type of ring. The type of ring for digital cartographic items.

	Not applicable. The type of ring is not applicable.

0	Outer ring. The closed non-intersecting boundary of the area covered.

1	Exclusion ring. The closed non-intersecting boundary of the area within the excluded G-polygon outer ring.

Subfields

ǂa Category of scale

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.
