Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation emitted from aircraft or satellites).

Famous quotes containing the words remote and/or sensing:
“The places which I have described may seem strange and remote to my townsmen ... our account may have made no impression on your minds. But what is our account? In it there is no roar, no beach-birds, no tow-cloth.”
—Henry David Thoreau (1817–1862)
“Something was still there, that something that distinguishes an artist from a performer: the revealing of self. Here I be. Not for long, but here I be. In sensing her mortality, we sensed our own.”
—Studs Terkel (b. 1912)
