Identification and mapping of landslides

Abstract

In order to study landslides using GIS, it is first necessary to identify landslides based on their characteristics: deep-seated landslides, such as main scarps, debris, mounds, and hollows, or shallow landslides. Deep-seated landslides are classified into rotational slide (slump), planar slide (glide), debris avalanche, or earth flows. Shallow landslides are composed of scar, flow, and deposit part. The seat is classified into planar or spoon type. After producing an inventory of landslides, an analog map should be transformed into a digital map and analyzed using GIS to obtain "landslide hazard maps" including: (1) landslide inventory maps, (2) landslide susceptibility maps, (3) landslide hazard maps, and (4) landslide risk maps. Finally, this chapter reviews on GIS landslide analyses and susceptibility mapping reviews briefly representative papers.
