Abstract
In this study, characteristics of landslide is considered from Remote Sensing data and DTM (Digital Terrain Model). A hill shading map, a sumit level map and a drinage pattern map were generated from DTM. A vegetation map and a landcover map were generated from LANDSAT TM as remote sensing data. From these maps, almost landslides were near an abundance of water resource which is stream or rice field. And landslide might be related with water erosion in topographical level.We suggest to use slope stability analysis for prediction of landslide. Generally, slope stability analysis has been applied to only the area where landslide had been occurred. However, we attempt to apply it to all areas regardless of landslide occurrence. A method of landslide risk mapping has been developed with use of Remote sensing data, DTM and ground survey data of geology and soil mechanics. The proposed method will be useful for preparedness of landslide prevention in the wide and steep terrain such as SHIKOKU Island, JAPAN where landslides occurred very often.
