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, such as when the cartographic item is not
digitally encoded data.
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:
- 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.
$b - Constant ratio linear horizontal scale Denominator of the representative fraction for the horizontal scale.
The larger scale (smaller number) is generally given first.

$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.
$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.

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).
Subfield $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).

the month in the form yyyy.mm (year-month).
$r - Distance from earth Distance of celestial bodies, such as planets or stars, from the Earth in
light-years in star atlases.
$s - G-ring latitude Latitude of a point of the g-ring.
$t - G-ring longitude Longitude of a point of the g-ring.

is assumed that the coordinate information is current.
$y - Ending date Ending of the date period of the data in which the coordinates describe. The date
is structured in the form of YYYYMMDD. When no date is recorded, it is
assumed that the coordinate information is current.
