PRINCIPLES OF REMOTE SENSINGS hefali AggarwalPhotogrammetry and REMOTE SENSING DivisionIndian Institute of REMOTE SENSING , Dehra DunAbstract : REMOTE SENSING is a technique to observe the earth surface or theatmosphere from out of space using satellites (space borne) or from the air usingaircrafts (airborne). REMOTE SENSING uses a part or several parts of theelectromagnetic spectrum. It records the electromagnetic energy reflected or emittedby the earth s surface. The amount of radiation from an object (called radiance) isinfluenced by both the properties of the object and the radiation hitting the object(irradiance).
computer, electronics and telecommunication, satellite launching etc. All these technologies are integrated to act as one complete system in itself, known as Remote Sensing System. There are a number of stages in a Remote Sensing process, and each of them is important for successful operation. Stages in Remote Sensing
