An application research on the landslide interpretation based on the technology of remote sensing three-dimension visualization

The fusion technique of remote sensing image and digital elevation model (DEM) is applied and the 3D image of researched region is made. The landslides are interpreted through the 3D image. The conclusion shows that the proposed method is better than the traditional methods. Landslide is a serious geologic hazard with serious results for the environment and zoology. Remote sensing interpretation is an important means to study the distribution of landslides. The technology of remote sensing three-dimension visualization and image dynamical analysis is synthetically utilizing the remote sensing (RS) and geography information system (GIS) to realize the three-dimension recurring and continuous cartoon of landslides. It provides a advanced method for studying landslides. The critical technology involves in several parts: the data fusion of multi-type RS images, making digital elevation model (DEM), fusion of DEM and image. It will effectively gain the information of landslides of research area through the dynamical analysis technology. We have analyzed some instances with the technology. It shows the three-dimension recurring is an important method for landslide study.
