Description/Instructions

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.

Editing instructions

Do not input a period at the end of the field.

First indicator - Type of scale

The first indicator position contains a value that specifies the type of scale information given.

0 Scale indeterminable/No scale recorded.

Value "0" indicates that no scale information is given. It is used when there is no representative fraction given in field 255.

Value "1" indicates that there is a single horizontal scale.

Value "3" indicates that the scale consists of a range of scales.

Second indicator - Type of ring

The second indicator position contains a value that identifies the type of ring for digital cartographic items.

Value # indicates that the type of ring is not applicable, such as when the cartographic item is not digitally encoded data.

Value "0" indicates that the coordinate information represents the closed non-intersecting boundary of the area covered.

Value "1" indicates that the coordinate information represents the closed non-intersecting boundary of an area within the G-polygon outer ring that is excluded.

Subfields

Subfield $a contains a one-character alphabetic code indicating the type of scale of the item. It is 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# a $b 100000

b Angular scale. Code "b" is used for celestial charts.

z Other type of scale. Code "z" indicates 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.

Subfield $b contains the denominator of the representative fraction for the horizontal scale. The larger scale (smaller number) is generally given first.

034 1# a $b 1000000

034 3# a $b 18000 $b 28000

$c Constant ratio linear vertical scale.

Subfield $c contains the 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# a $b 744000 $c 96000

$d Coordinates - westernmost longitude.

$e Coordinates - easternmost longitude.

$f Coordinates - northernmost latitude.

$g Coordinates - southernmost latitude.

Subfield codes $d, $e, $f, and $g individually identify the four coordinates given in field 255. Subfield $d identifies the westernmost extent of the item, subfield $e identifies the easternmost extent of the item, subfield $f identifies the northernmost extent of the item, and subfield $g identifies the southernmost extent of the item. These four subfields must always appear together. Each subfield is eight characters in length. The abbreviations for the hemispheres are: N = North, S = South, E = East, and W = West.

The
coordinates are recorded in the form *hdddmmss*
(hemisphere-degrees-minutes-seconds). The degree, minute, and second
elements are each right justified with leading zeros.

034 1# a $b 22000000 $d W1800000 $e E1800000 $f N0840000 $g S0700000

034 1# a $b 253440 $d E0790000 $e E0860000 $f N0200000 $g N0120000

[These examples illustrate records for flat maps or flat maps in atlases.]

If the coordinates for a map or plan are given in terms of a center point rather than outside limits, the longitude and latitude that form the central axis are recorded twice (in subfields $d and $e and in $f and $g respectively).

034 1# a $b 75000 $d W0950500 $e W0950500 $f N0303000 $g N0303000

Subfield $h contains the 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.

The declination is recorded in subfield
$j and $k
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 knows,
it is repeated in both subfields.)

The
right ascension is recorded in subfield $m
and $n 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 the center
is known, it is repeated in both subfields.)

034 0# b $j N0300000 $k N0300000 $m 021800 $n 021800

Subfield $p
contains the equinox or epoch for a celestial chart. It is
usually recorded in the form *yyyy
*(year) according to the Gregorian
calendar, but may include a decimal including the month in the form *yyy.mm*
(year-month).

034 0# b $p 1950

Subfield $s contains the latitude of a point of the g-ring.

Subfield $t contains the longitude of a point of the g-ring.

For instructions on the use of subfield $6, see field 880.
