Abstract
In this study, fusion of Landsat TM, SPOT and ERS SAR Images were done, and then an orthphotomap of the fusion image of Landsat TM453 and SPOT panchromatic image of Yunyang area, the Yangtze Three Gorges Project Region was made, which is in 1:50000 scale and up to an international standard of topographic map. With the orthphotomap, many new geological structures and disasters were identified and positioned. The biggest landslide in the Yangtze River region-JIPAZI landslide was digitized. 3D quantitatively analyzing patterns for surveying landslides and rockfalls were established with RS, GIS and GPS techniques. Through phase- separation analysis of remote sensing information field and quantitative processing of the linear structures, the relationship between geological disasters and crack structures was found out. Finally, with a synthetic analysis, these landslides and rockfalls probably to stop up river water and their environmental influence were predicted.
