Definition​

This is a sub-area within the Material or Type of Resource Specific Area (Area 3) specifically for cartographic resources. It includes details like scale, projection, coordinates, celestial hemisphere, epoch, equinox, and magnitude, which are essential for describing maps, charts, and globes.

Required Elements​

  • Statement of scale (Mandatory if applicable): Given as a representative fraction (e.g., "1:25 000"). Can include vertical scale for relief models or angular scale for celestial charts.
  • Statement of projection (Mandatory if available): The name of the projection (e.g., "universal transverse Mercator proj."), possibly with associated phrases.
  • Statement of coordinates and celestial hemisphere (Mandatory if available): This covers:
    • Terrestrial coordinates: Longitude and latitude in degrees, minutes, and seconds, with cardinal directions.
    • Celestial coordinates (Right ascension and declination): RA in hours/minutes/seconds and Decl. in degrees/minutes/seconds, with +/- for hemispheres.
    • Other celestial coordinate systems: Ecliptic, galactic, supergalactic coordinates.
    • Celestial hemisphere: Indication of northern, southern, or both hemispheres.
  • Statement of epoch and equinox (Mandatory if available): A reference moment in time for position measurements (epoch) and one of the intersection points of the ecliptic and celestial equator (equinox).
  • Statement of magnitude (Mandatory if available): For celestial charts, the brightness magnitude (e.g., "limiting magnitude 3.5").

Punctuation Rules​

  • The projection statement is preceded by ;.
  • The statements of coordinates, celestial hemisphere, epoch and equinox are enclosed in one pair of parentheses ( ).
  • The statement of equinox is preceded by ;.
  • The statement of celestial hemisphere is preceded by ;.
  • The statement of magnitude is preceded by ;.
  • Within coordinates, pairs are separated by / (no space), and ranges by – (no space).

Relationship to ISBD Standards​

This is element 3.1 within Area 3. The 2021 Update broadened and refined the description of cartographic resources, clarifying stipulations and reorganizing elements, especially for celestial cartography.

Relationship to Other SES​

It is a key component of the "Material Or Type Of Resource Specific Area Encoding Scheme." Notes can provide additional mathematical or cartographic data, including details on digital graphic representation.

Examples​

  • . — Scale 1:250 000 ; universal transverse Mercator proj.
  • . — Scale 1:25 000 (E 79°–E 86°/N 20°–N 12°)
  • . — RA 16 h/Decl. -23° ; equinox 1950)
