Environmental Data Coding Specification

1 Scope

This International Standard establishes concepts to ensure that environmental information is:

  1. unambiguously defined,
  2. flexibly denoted and encoded, and
  3. easily bound in exchange formats and to programming languages.

This International Standard specifies:

  1. classifications that define the type of environmental objects,
  2. attributes that define the state of environmental objects, and
  3. enumerants and units of measure that define how values of state are characterized.

This International Standard specifies labels and codes because denoting and encoding a concept requires a standard way of identifying the concept.

This International Standard is applicable, but is not limited to:

  1. abstract concepts (for example: absolute latitude accuracy, geodetic azimuth),
  2. airborne particulates and aerosols (for example: cloud, dust, fog, snow),
  3. animals (for example: civilian, fish, human, whale pod),
  4. atmosphere and atmospheric conditions (for example: air temperature, humidity, rain rate, sensible and latent heat, wind speed and direction),
  5. bathymetric physiography (for example: bar, channel, continental shelf, guyot, reef, seamount, water body floor region),
  6. electromagnetic and acoustic phenomena (for example: acoustic noise, frequency, polarization, sound speed profile, surface reflectivity),
  7. equipment (for example: aircraft, spacecraft, tent, train, vessel),
  8. extraterrestrial phenomena (for example: asteroid, comet, planet),
  9. hydrology (for example: lake, rapids, river, swamp),
  10. ice (for example: iceberg, ice field, ice peak, ice shelf, glacier),
  11. man-made structures and their interiors (for example: bridge, building, hallway, road, room, tower),
  12. ocean and littoral surface phenomena (for example: beach profile, current, surf, tide, wave),
  13. ocean floor (for example: coral, rock, sand),
  14. oceanographic conditions (for example: luminescence, salinity, specific gravity, turbidity, water current speed),
  15. physiography (for example: cliff, gorge, island, mountain, reef, strait, valley region),
  16. space (for example: charged particle species, ionospheric scintillation, magnetic field, particle density, solar flares),
  17. surface materials (for example: concrete, metal, paint, soil), and
  18. vegetation (for example: crop land, forest, grass land, kelp bed, tree).

Figure 1.1 illustrates some of these concepts.
