Landslide Susceptibility Mapping Using GIS Author: Chandrasekaran Sivapragasam 10, Kent Ridge Crescent Phone: 0065-8735721 Landslides are one of the potential earth hazards severely affecting the Asia Pacific region. Recent developments in GIS technology have provided us with a wide range of effective tools and techniques for assessing landslide hazard. The spatial variation of landslide hazard is generally represented using landslide susceptibility maps. Landslide susceptibility mapping involves spatial integration of morphologic and geologic parameters. Many complex and highly data-intensive mathematical models have been proposed by various researches in the past to analyze and map landslide susceptibility. In most of the Asia Pacific regions, such high-resolution data is not easily available. The present paper discusses a set of specific GIS-based models for generating landslide susceptibility maps at reasonable levels of accuracy using available input data. |
