文摘内容 In order to apply Satellite Remote Sensing(RS) to minig areas,some key issues should be solved,Based on an introduction to relative studying background,related key issues are propsed and analyzed oriented to the devel-opment of RS information science and demands of mining aress ,Band selection and combination optimization of Landsat TM is discussed firstly,and it proved that the combination of Band 3 ,Band 4 and Band 5 has the largest informaiton amount in all three-band combination schemes by both N-dimensional entropy method and Genetic Algorithm(GA) ,After that the filtering of Radarsat image is disccussed ,Different filtering methods are experimented and compared,and adaptive methods are more efficient than others,Finally the classification of Satellite RS image is studied,and some new methods including classification by improved BPNN (Back Propagation Neural Network) and classification based on GIS and knowledge anre propsed。
