034 - CODED CARTOGRAPHIC MATHEMATICAL DATA (R)
The coded form of the mathematical data contained in field 255 (Mathematical Data Area) of the bibliographic record.
Indicators
- First - Type of scale
A value that indicates the type of scale contained in the field.- 0 - Scale indeterminable/No scale recorded
No representative fraction is given in field 255.
- 1 - Single scale
- 3 - Range of scales
- 0 - Scale indeterminable/No scale recorded
- Second - Type of ring
- # - Not applicable
- 0 - Outer ring
- 1 - Exclusion ring
Subfield Codes
- $a - Category of scale (NR)
A one-character code that indicates the type of scale of the item.- a - Linear scale
- b - Angular scale
Used for celestial charts.
- z - Other type of scale
- $b - Constant ratio linear horizontal scale (R)
The denominator of the representative fraction for the horizontal scale. - $c - Constant ratio linear vertical scale (R)
The 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 pattern hdddmmss however other forms are also allowed such as decimal degrees. The subelements are each right justified and each unused position contains a zero. - $h - Angular scale (R)
The scale for celestial charts. - $j - Declination--northern limit (NR)
- $k - Declination--southern limit (NR)
Subfields $j and $k are each eight characters in length and consist of the hemisphere degree minutes and seconds of the declination of a celestial chart recorded in the pattern hdddmmss. The degree minute and second subelements are each right justified with and each unused position contains a zero. - $m - Right ascension--eastern limit (NR)
- $n - Right ascension--western limit (NR)
Subfields $m and $n are each six characters in length and consist of the right ascension of a celestial chart recorded in the pattern hhmmss. Each subelement is right justified and each unused position contains a zero. - $p - Equinox (NR)
The year or year and month of a celestial chart recorded in the pattern yyyy.mm. - $s - G-ring latitude (R)
- $t - G-ring longitude (R)
- $6 - Linkage (NR) See Control Subfields
- $8 - Field link and sequence number (R) See Control Subfields
