Interpretation and Mapping for the Prediction of Sites at Risk of Landslide Disasters: From Aerial Photography to Detection by DTMs
摘要
By grasping the slope topography three-dimensionally and typifying and mapping the landform features, it is possible to visualize the areas at risk of landslide-induced disasters. This effort began with the interpretation of aerial photographs, and, in recent years, has shown great development with the advancement of remote sensing technology. In this chapter, we introduce the characteristics that can be extracted from remote sensing data that can be used to identify potential areas exposed to mass movement processes and landslide-induced disasters. In addition, we created a manual for landslide recognition by aerial photographs, AW3D-based wide-area maps, and specific landslide microtopography maps, which can be freely used to identify landslide landforms.
