Visualization of 3-D digital elevation model for landslide assessment and prediction in mountainous terrain: A case study of Chandmari Landslide, Sikkim, eastern Himalayas Chandra Shekhar Dubey , Manoj Chaudhry , Braj Kishore Sharma , Chandra Pandey and Bhoop Singh
Abstract
Techniques for recognizing and mapping of landslides are complex in mountainous terrains. Most of the methods applied to landslide identification and prediction involves assignment of different contributing factors in landslide hazard zonation; however, it is difficult to observe the main causes of landslides. 3-D digital elevation modeling capabilities and Guided Visual Program (GVP) module of Datamine Software is utilized to successfully enumerate the various contributing factors for causing the landslide in Sikkim, Eastern Himalaya in the case study of Chandmari Landslide. A landslide warning system is discussed for the site-specific Chandmari landslide area.
