[Abstract]:First of all, the techniques of acquiring the digital elevation model (DEM), such as high remote sensing stereo measurement, synthetic aperture radar interferometry, lidar ranging and motion reconstruction, are analyzed. As well as the main features of the (VHR DEM) extraction technology of high spatial resolution digital elevation model at present, it is necessary to select the appropriate VHR DEM acquisition technology according to the topographic and geomorphological characteristics of the study area in practical application. Then, the latest applications of VHR DEM in active fault identification and geometric structure analysis, coseismic displacement and cumulative displacement acquisition and paleoseismicity research are described in combination with the latest research results. Finally, it is pointed out that because of its high precision and high spatial resolution, VHR DEM is gradually changing the traditional active fault research method, which makes the research of active fault into an unprecedented level of refinement.
