| The paper selected the area of Yin-xi-ru-lan transporting water engineering in the Anshan City and processed the SPOT5 image of the area, on the famous of remote sensing image processing system of ENVI from Singapore. Firstly, the author did radiation correction, geometric correction, color composing, data fusion and many wave band difference analysis; Secondly, the author enhanced the precision of extraction and identification of the linear fault information on the base of spectrum information enhancement, primary component transformation and adverse transformation and spatial information enhancement; at last, according to the basic principle that is from whole to part, from structure to lithology and from simple to complex, the author did the systemic remote sensing engineering geologic analysis and mark off stratum lithology and fault structure of the area on the base of hue, image texture and physiognomy character which will have an important guiding sense to geologic survey in the future.
