ABSTRACT

Remote sensing is the science of marking inferences about objects from measurements made at a distance. Remote sensing of earth resources using space-borne sensors is accepted as a useful tool by the application scientists for generating inputs to the natural resources management system. Undoubtedly, it is the fastest and cheapest means of obtaining information of a vast area of the earth’s surface. The data are obtained using satelliteborne sensors available in the optical and nonoptical ranges of electromagnetic spectrum.
