This International Standard provides mechanisms to unambiguously specify objects used to model environmental concepts. To accomplish this, a collection of nine EDCS dictionaries of environmental concepts are specified: classifications: specify the type of environmental objects; attributes: specify the state of environmental objects; attribute value characteristics: specify information concerning the values of attributes; attribute enumerants: specify the allowable values for the state of an enumerated attribute; units: specify quantitative measures of the state of some environmental objects; unit scales: allow a wide range of numerical values to be stated; unit equivalence classes: specify sets of units that are mutually comparable; organizational schemas: useful for locating classifications and attributes sharing a common context; and groups: into which concepts sharing a common context are collected. A functional interface is also specified. This International Standard specifies labels and codes because denoting and encoding a concept requires a standard way of identifying the concept. This International Standard specifies environmental phenomena in categories that include, but are not limited to, the following: abstract concepts (i.e. absolute latitude accuracy, geodetic azimuth); airborne particulates and aerosols (i.e. cloud, dust, fog, snow); animals (i.e. civilian, fish, human, whale pod); atmosphere and atmospheric conditions (i.e. air temperature, humidity, rain rate, sensible and latent heat, wind speed and direction); bathymetric physiography (i.e. bar, channel, continental shelf, guyot, reef, seamount, waterbody floor region); electromagnetic and acoustic phenomena (i.e. acoustic noise, frequency, polarization, sound speed profile, surface reflectivity); equipment (i.e. aircraft, spacecraft, tent, train, vessel); extraterrestrial phenomena (i.e. asteroid, comet, planet); hydrology (i.e. lake, rapids, river, swamp); ice (i.e. iceberg, ice field, ice peak, ice shelf, glacier); man-made structures and their interiors (i.e. bridge, building, hallway, road, room, tower); ocean and littoral surface phenomena (i.e. beach profile, current, surf, tide, wave); ocean floor (i.e. coral, rock, sand); oceanographic conditions (i.e. luminescence, salinity, specific gravity, turbidity, water current speed); physiography (i.e. cliff, gorge, island, mountain, reef, strait, valley region); space (i.e. charged particle species, ionospheric scintillation, magnetic field, particle density, solar flares); surface materials (i.e. concrete, metal, paint, soil); and vegetation (i.e. crop land, forest, grass land, kelp bed, tree).
