The First Decade for “Digital Landslide” in China

摘要

10 years have passed since “Digital Landslide” concept and technique were proposed, which radically changed the methods of earlier stage landslide remote sensing in aspects of landslide information capturing, analysis and storage, as well as expressions style of interpretation results. With “digital landslide” we can more accurately locate the position of the landslides and capture their information; more scientifically and efficiently store and manage the survey results; more conveniently and faster transport and exchange landslide information. For 10 years, with “digital landslide” which under the guide of the landslide geo-theory, and the support of the modern informatics technique and the pressing need by landslide disaster mitigation and prevention work, large numbers of landslides and geological environment investigation has done such as over 10×104km2 on 1:10, 000-1:50, 000 scale and 180×104km2 on 1:1, 000, 000 scale regional landslides and its geological environment remote sensing investigating in enter Tibet railway line region have been carried out, and large scale landslides occurred in recent years in China such as Yigong, Qianjiongping, Tiantai village Yanmen village and Pali landslide…and so on meticulous remote sensing survey have been carried out that improve landslide survey and theory study in a great extent. “Digital Landslide” technique would develop continually towards some aspects of more precise and accuracy survey, TGIS analysis, digital simulation and technique integration.
