Remote sensing for landslides in China as a main means for regional landslide investigation has a history

of more than 20 years, and has made important contributions to survey, mitigation and prevention of landslide

disasters in  large-scale engineering construction of mountainous areas. With the adoption of “digital landslide”

technique and high resolution remote sensing data since the end of the 20th Century, Remote sensing for landslides

has acquired the capacity for more exact qualitative and quantitative landslide survey, even for detailed survey and

monitoring of large-size independent landslides. The realization of“digital landslide”technique depends on the

support of remote sensing, digital photogrammetry and image-processing, GIS and computer technique. The“digital

landslide”technique can be divided into three parts, i.e., acquisition of basic landslide information, information

storage and management, and thematic service technique. With Tiantaixiang landslide, Three Gorges area, Jinglong

Mountain landslide remote sensing investigation and Yigong landslide remote sensing monitoring as examples, this

paper deals with the thematic service technique of “digital landslide”.
