Scope of the EDCSIncludes, but is not limited to:

• Abstract concepts (absolute latitude accuracy, geodetic azimuth),

• Airborne particulates and aerosols (cloud, fog, snow),

• Animals (civilian, fish, human, whale),

• Atmosphere and atmospheric conditions (air temperature, precipitation rate, pressure Altitude, wind speed and direction),

• Bathymetric physiography (continental shelf, guyot, reef, seamount),

• Electromagnetic and acoustic phenomena (acoustic noise, frequency, polarization, surface reflectivity),

• Equipment (aircraft, artificial satellite, tent, train, vessel),

• Extraterrestrial phenomena (comet, planet, spacecraft),

• Hydrology (lake, rapids, river, swamp),

• Ice (ice field, ice peak, ice shelf, glacier),

• Man-made structures and their interiors (bridge, building, hallway, road, room, town),

• Ocean and littoral surface phenomena (current, surf, tide, wave),

• Ocean floor (coral, rock, sand),

• Oceanographic conditions (luminescence, salinity, specific gravity, water current speed),

• Physiography (cliff, gorge, mountain, valley region),

• Space (charged particle species, ionospheric scintillation, magnetic field, particle density),

• Surface materials (concrete, metal, paint, soil), and

• Vegetation (crop land, forest, grass land, kelp bed, tree).
