Earth Science

In the broadest sense, the measurement or acquisition of information of some property of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object or phenomenon under study; e.g., the utilization at a distance (as from aircraft, spacecraft, or ship) of any device and its attendant display for gathering information pertinent to the environment, such as measurements of force fields, electromagnetic radiation, or acoustic energy. The technique employs such devices as the camera, lasers, and radio frequency receivers, radar systems, sonar, seismographs, gravimeters, magnetometers, and scintillation counters.

The practice of data collection in the wavelengths from ultraviolet to radio regions. This restricted sense is the practical outgrowth from airborne photography. Sense (1) is preferred and thus includes regions of the EM spectrum as well as techniques traditionally considered as belonging to conventional geophysics.

Group of techniques for collecting image or other forms of data about an object from measurements made at a distance from the object, and the processing and analysis of the data.

Remote sensing is the measurement and analysis of electromagnetic radiation reflected from, transmitted through, or absorbed and scattered by the atmosphere, the hydrosphere and by material at or near the land surface, for the purpose of understanding and managing the Earth's resources and environment.

The acquisition of information about an object, without being in physical contact with that object.

Remote Sensing: the science and art of obtaining useful information about an object, area or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation.

Remote sensing is the collection of natural resources and environmental information using images acquired by sensors on board aircraft or spacecraft.

Remote sensing may be broadly defined as the collection of information about an object without being in physical contact with the object. Aircraft and satellites are the common platforms from which remote sensing observations are made. The term remote sensing is restricted to methods that employ electromagnetic energy as the means of detecting and measuring target characteristics.

Aerial Radar of Region Surrounding Lost City of Ubar

Radar image taken from the Space Shuttle Endeavour of the region surrounding the lost city of Ubar in Oman. Archeologists believe Ubar existed from about 2800 B.C. to about 300 A.D. and was a remote desert outpost where caravans were assembled for the transport of frankincense across the desert. The magenta region is large sand dunes, the green region is limestone rock on the desert floor, and a wadi, or dry riverbed, shown in white, runs through the middle of the image.
