Application of GNSS-supported static terrestrial lidar in mapping landslide processes in the Himalaya

Site-specific topographic survey of 15 landslides in the four mountainous states of India, namely Uttarakhand, Jammu & Kashmir, Sikkim and Nagaland, was carried out through a terrestrial laser scanner campaign. The versatility of the lidar instrument in topographic surveys and its advantages over conventional survey practices are highlighted. The effective use of the static terrestrial lidar in the rapid characterization and hazard assessment of landslides in this study is presented for adoption as a meaningful hazard assessment strategy in the hilly terrains
