[email protected] Abstract: Remote sensing is the science of making inferences about objects from measurements, made at a distance, without coming into physical contact with the objects under study. This article gives a basic introduction to remote sensing and its recent advancements and its applications. Key Words: Remote Sensing, Electromagnetic Spectrum, Digital Image Processing, Image Enhancement, GPS, GIS, ERDAS. Introduction Remote sensing is the science of acquiring information about the earth’s surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing and applying that information. Exploration of earth’s natural resources is vital for the socio-economic development of any country. The various studies carried out in India and elsewhere in the world proves beyond doubt that remote sensing is a powerful tool for mapping inventorying, monitoring and managing of natural resources due to the inherent advantages of synoptic viewing, repetitive imaging, capability to study inaccessible areas, relatively at low cost and real time/near real time availability of data.
