The purpose of this study is to develop landslide susceptibility analysis technique usinf artificial neural network and apply the newly developed techniques for assessment of landslide susceptibility to study area. Yongin. Landslide locations detected from interpretation of aerial photo and field survey, and topographic, soil and geological maps of the Yongin area were collected. The data of the locations of landslide, slope, soil and geological maps of the Yongin area were collected. The data of the locatins of landslide, slope, soil texture, topography and lithology were constructed into spatial database using GIS. Usinf the factors, landslide susceptibility was analyzed by artificial neural network methods. The results of the analysis were verified usinf the landslide location data. The validation results showed satisfactory agreement between the susceptibility map and landslide location data.
