Landslide Hazard and Its Mapping Using Remote Sensing and Gis
نویسندگان
چکیده
Landslides are amongst the most damaging natural hazards in the mountainous terrain like Himalaya. The study of landslides has drawn worldwide attention mainly due to increasing awareness of socio-economic impacts of landslides. Remote sensing images provide many useful land use information to combine in a GIS environment with other spatial factors influencing the occurrence of landslide. The landslide inventory is a fundamental prerequisite for landslide hazard analysis based on GIS. The satellite imageries of LANDSAT ETM+, IRS P6, ASTER etc. along with Survey of India (SOI) topographical sheets form the basis for deriving baseline information on various parameters like slope, aspect, relative relief, drainage density, geology/lithology and land use/land cover. Keyword: Landslide, Himalaya, GIS, Remote Sensing Image, Survey of India etc.
