Remote Sensing and GIS Applications in Environmental Sciences – A Review

Remote sensing and Geographic Information System play a pivotal role in environmental mapping, mineral exploration, agriculture, forestry, geology, water, ocean, infrastructure planning and management, disaster mitigation and management etc. Remote Sensing and GIS has grown as a major tool for collecting information on almost every aspect on the earth for last few decades. In the recent years, very high spatial and spectral resolution satellite data are available and the applications have multiplied with respect to various purpose. Remote sensing and GIS has contributed significantly towards developmental activities for the four decades in India. In the present paper, we have discussed the remote sensing and GIS applications of few environmental issues like Mining environment, Urban environment, Coastal and marine environment and Wasteland environment.
