Remote Sensing is a technology that is used for collecting and analyzing information and examine about objects or phenomenon without making any physical contact with it. This technology used to in several kind of fields like geography, ecology, geology, hydrology, glaciology and oceanography.
However, conventionally, Remote sensing refers to the identification of earth features by detecting the characteristic electromagnetic radiation that is reflected by the earth surface.
In simply, we can say that the technology which can sense from camera or sensor without physical contact that is remote sensing.
Remote sensing uses sensors mounted on different platform to measures energy response. Sensors are either active or passive. Active sensors illuminate a target with a know energy source and measure the time, phase, intensity and other characteristics of the reflected energy. Passive sensors measure natural energy usually sunlight that is reflected or emitted form an object.
