Spatial Deterministic Modelling of Landslide in Chamoli Area

The high susceptibility to landslides of the Himalayan terrain is mainly due to a complex geological setting combined with contemporary crustal movement, varying slopes and relief, heavy rainfall, along with increasing human interference of human in ecosystem. The paper presents Remote Sensing and GIS based spatial data analysis for landslide mapping in Chamoli district using IRS 1C LISS III, IRS 1C PAN image. Landslide map were prepared to understand the parameter which is influencing landslides. It includes the derivation of input parameters from remotely sensed data with limited field check. Factor of safety map is also calculated for the study area.
