Remote Sensing Components
1) Target: the object or material that is being Studied.
2) Energy source: may be natural source or artificial ”ex,., sun, radar”.
3) Transmission path: The passage of radiation from a source of energy to the target then to the sensor.
4) Sensor: is the device that measures the reflected and emitted rays from the target.
What Is Remote Sensing ?
Remote sensing is defined as a technique for getting information about objects by analyzing data collected by instruments that were not in direct contact with the objects. Or, it is the art and science involving the detection, identification, classification, delineation, and analysis of earth surface features and phenomena using imagery acquired from terrestrial, aircraft and satellite platforms equipped with photographic and non-photographic sensors using visual and computer-assisted interpretation techniques.
