What is remote sensing?

Remote sensing is the science and art of obtaining information about a phenomenoa without being in contact with it. Remote sensing deals with the detection and measurement of phenomena with devices sensitive to electromagnetic energy such as:
Light (cameras and scanners)
Heat (thermal scanners)
Radio Waves (radar)

How is remote sensing useful?

It provides a unique perspective from which to observe large regions.
Sensors can measure energy at wavelengths which are beyond the range of human vision (ultra-violet, infrared, microwave).
Global monitoring is possible from nearly any site on earth.
