Remote Sensing and GIS in Environment Management and Sustainability - Uses of Modern Technology to Conserve Environment

Abstract

Environment as a whole consist of Land, Water, Air and all the physical features that are directly and indirectly related with it. Today our Environment is in dire state and is getting depleted day by day. The world has entered in a technical era and everyday scaling new heights in technology, but everything have “cause effect relationship” and in this phase the effect is on environment. Now every country is facing environmental problems and the experts are on their toes to mitigate the risk in every possible way, it is kind of emergency that whole world is going through and the role of Modern information and technology has increased in manifolds. The technical capabilities of the sensors, space platform, data communication, GPS, Digital image processing system are contributing in level playing role. The success of many applications of remote sensing is improved considerably by taking a multiple view approach to data collection. In the multistage approach, satellite data may be analyzed in conjunction with high altitude data and ground observations. Each successive data may provide more detailed information over smaller geographic areas. It is so broad in its application that nobody owns the field. The remote sensing data is useful in monitoring, managing earth resources and us to understand the global ecosystem.
