Remote Sensing

3:59 PM mayuravaani

Remote means far away. Remote sensing means sensing things from a distance. We use three as remote sensors of our five senses. Sense of sight (watching cricket from the stands), Sense of smell (smell freshly baked food) and sense of hearing (hear a telephone call) are remote sensors.

Remote sensing is used in numerous fields. There are two types of remote sensing. Passive remote technology is used to record an object’s natural radiation. For example, an infrared camera on a tripod that records heat coming from a rock formation or an airplane flying over a rain forest that registers the sunlight reflected from the forest as canopy.

“” Science and art of identifying, observing and measuring an object without coming into direct contact “
-Ms. Evelyn Pruitt of the U.S office Naval Research

Active remote technology takes place when a device sends out a signal in order to gather information about an object. For example, Ships that send sonar waves to scan the ocean floor uses active remote sensing.
