034 - Coded Cartographic Mathematical Data (R)
MARC 21 Bibliographic - Concise
2007
Coded form of the mathematical data contained in field 255 (Mathematical Data Area) of
the bibliographic record.
Indicators
First - Type of scaleSpecifies 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
3 - Range of scales
Second - Type of ring
# - Not applicable
0 - Outer ring
1 - Exclusion ring
Subfield Codes
$a - Category of scale (NR)
One-character alphabetic code indicating the type of scale of the item.
- 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.
$b - Constant ratio linear horizontal scale (R)
Denominator of the representative fraction for the horizontal scale.
$c - Constant ratio linear vertical scale (R)
Denominator of the representative fraction for the vertical scale of relief models
and other three-dimensional items.
$d - Coordinates - westernmost longitude (NR)
$e - Coordinates - easternmost longitude (NR)
$f - Coordinates - northernmost latitude (NR)
$g - Coordinates - southernmost latitude (NR)
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.
$h - Angular scale (R)
Scale, if known, for celestial charts.
$j - Declination - northern limit (NR)
$k - Declination - southern limit (NR)
$m - Right ascension - eastern limit (NR)
$n - Right ascension - western limit (NR)
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).
$p - Equinox (NR)
Equinox or epoch for a celestial chart. Usually recorded in the form yyyy
(year) according to the Gregorian calendar, but may include a decimal including
the month in the form yyyy.mm (year-month).
$r - Distance from earth (NR)
Distance of celestial bodies, such as planets or stars, from the Earth in
light-years in star atlases.
$s - G-ring latitude (R)
$t - G-ring longitude (R)
$x - Beginning date (NR)
Beginning 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.
$y - Ending date (NR)
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.
$z - Name of extraterrestrial body (NR)
Name of a planet or other extraterrestrial body specified when the coordinate data
recorded in subfields $d, $e, $f and
$g do not describe an entity on Earth.
$8 - Field link and sequence number (R)
