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).
