### FIELD DEFINITION AND SCOPE

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. There should be an 034 field corresponding to each 255 field in a record.

For relief models and other three-dimensional 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.

### GUIDELINES FOR APPLYING CONTENT DESIGNATORS

#### ■ INDICATORS

First Indicator - Type of scale

Specifies the type of scale information given.

0 - Scale indeterminable/No scale recorded

Used when no representative fraction is given in field 255.

1 - Single scale

Single horizontal scale.

3 - Range of scales

Scale consists of a range of scales.

Second Indicator - Type of ring

Type of ring for digital cartographic items.

# - Not applicable

Type of ring is not applicable.

0 - Outer ring

Coordinate information represents the closed non-intersecting boundary of the area covered.

1 - Exclusion ring

Coordinate information represents the closed non-intersecting boundary of an area within the G-polygon outer ring that is excluded.

#### ■ SUBFIELD CODES

\$a - Category of scale

One-character alphabetic code indicating the type of scale of the item.

Used even when a specific scale is not recorded (first indicator position contains value 0). The codes used in subfield \$a are:

a - Linear scale

 034 1#\$aa\$b100000
b - Angular scale

Used for celestial charts.

z - Other type of scale

Any other type of scale, for example, a time scale, quantitative statistical scale, etc.

If the scale statement is the only subfield given in field 255 and if the scale statement does not contain a representative fraction, field 034 will contain only subfield \$a.

 034 0#\$aa

\$b - Constant ratio linear horizontal scale

Denominator of the representative fraction for the horizontal scale.

The larger scale (smaller number) is generally given first.

 034 1#\$aa\$b1000000 034 3#\$aa\$b18000\$b28000

\$c - Constant ratio linear vertical scale

Denominator of the representative fraction for the vertical scale of relief models and other three-dimensional items.

The larger scale (smaller number) is generally given first.

 034 1#\$aa\$b744000\$c96000

\$d - Coordinates - westernmost longitude

\$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 item. 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.

Examples in degrees/minutes/seconds: hdddmmss (hemisphere-degrees-minutes-seconds):

 034 1#\$aa\$b22000000\$dW1800000\$eE1800000\$fN0840000\$gS0700000 034 1#\$aa\$b253440\$dE0790000\$eE0860000\$fN0200000\$gN0120000[The above two examples illustrate records for flat maps or flat maps in atlases.]

Example in decimal degrees: hddd.dddddd (hemisphere-degrees.decimal degrees):

 034 1#\$aa\$dE079.533265\$eE086.216635\$fS012.583377\$gS020.419532

Example in decimal degrees: +-ddd.dddddd (hemisphere[+/-]-degrees.decimal degrees) (“+” for N and E, “-“ for S and W; the plus sign is optional):

 034 1#\$aa\$d+079.533265\$e+086.216635\$f-012.583377\$g-020.419532

Example without the optional plus sign:

 034 1#\$aa\$d079.533265\$e086.216635\$f-012.583377\$g-020.419532

Example in decimal minutes: hdddmm.mmmm (hemisphere-degrees-minutes.decimal minutes):

 034 1#\$aa\$dE07932.5332\$eE08607.4478\$fS01235.5421\$gS02028.9704

Example in decimal seconds: hdddmmss.sss (hemisphere-degrees-minutes-seconds.decimal seconds):

 034 1#\$aa\$dE0793235.575\$eE0860727.350\$fS0123536.895\$gS0202858.125

If the coordinates for a map or plan 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).

\$h - Angular scale

Scale, if known, for celestial charts.

\$j - Declination - northern limit

\$k - Declination - southern limit

\$m - Right ascension - eastern limit

\$n - Right ascension - western limit

Subfields \$j, \$k, \$m, and \$n are used with celestial charts or celestial charts in atlases 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).

Subfields \$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).
