A Study on Estimation of Areas Damaged by Landslide due to Heavy Rainfall

摘要

This study aimed to take a rapid detection and follow-up measures of Landslide using terrestrial LiDAR. HyangChon village, which is close to Uymeon mountain in Seoul, Korea, was heavily damaged by landslide last summer 2011 and we conducted laser scanning to obtain the 3D pointcloud data of damaged place. VRS GPS was also used for the geo-referencing of data acquisitions. Then, the 3D pointcloud data obtained by terrestrial LiDAR was co-registered with the airborne LiDAR data, which was obtained before landslide, and the damaged area was estimated. This result is expected to be used for rapid detection and fast recovery of disaster area.
