What is Remote Sensing Technology
Remote Sensing Introduction The term "remote sensing," first used in the United States in the 1950s by Ms. Evelyn Pruitt of the U.S. Office of Naval Research. ‘Remote’ means far away and ‘sensing’ means observing or acquiring some information. Therefore, r emote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object. In our everyday living, one employ remote sensing to view different objects. Our eyes can be considered as sensors that respond to the light reflected from various objects. The data acquired by our eyes are the impulses corresponding to the amount of light reflected from light and dark areas of the object. This data is analyzed and interpreted by our brain which works like computer, to enable us to recognize the object. Remote sensing is a tool/technique that use sensors to measure the amount of electromagnetic energy emitting an object or geographic area from a distance and then
