| Abstract: | with regard to phenomenon of landslide and debris flow taken place frequently in earthquake area,this paper analyzes extraction method of landslide and debris flow information based on optical remote sensing data and SAR data.For optical remotely sensed data,multi-phase image feature was analyzed to identify the change result from landslide and debris flow;for SAR data,feature analyses method is used.Results show that the method can give a reference to landslide and debris flow identification. |
