A study of remote sensing image features of typical landslides

The image features of landslides with different kinds of geological conditions,types and runout distances show great difference in remote sensing images with different resolutions.For long-runout landslide and complex landslide,the available interpretation keys are few,so that the identification of landslide mainly relies on ground survey.On the basis of the achievements of landslide remote sensing investigation obtained both in China and abroad and the remote sensing investigation projects for geological hazards,the authors analyzed the remote sensing image features of typical landslides,including Daqingkan Landslide,Qianjiangping Landslide,Wulong Landslide and 102 landslide group in Tibetan region.Then,the interpretation keys to landslides,especially to the high-speed and long-runout landslides,were summarized for colleagues'reference.
