ABSTRACT
Mining and opencast mining may lead to severe environmental degradation. Continuous monitoring of the lands is essential for their effective reclamation and environmental management. Chemical properties of water and feed used in aquaculture have significant impact on soil fertility. Shifting cultivation is the most complex and multifaceted form of agriculture in the world. Both aerial photographs and spaceborne multispectral measurements have been utilized for assessment and monitoring of areas subject to mining, aquaculture, and shifting cultivation. Remote sensing technique is quite useful in the detection, inventory, monitoring, and quantifying active surface mining activities or abandoned mining problems. The detection and delineation of aquaculture areas is based solely on their spectral response pattern as seen in the image or as portrayed in the changes in spectral radiance values of spaceborne multispectral data. Preparation of database involves geo-referencing, radiometric normalization, and data fusion.
