Abstract

This study utilized high quality three-dimensional geospatial information produced by high-resolution Digital Aerial Photograph and Airborne LiDAR data in order to analyse landslides and debris flows induced by the heavy rainfall in Chuncheon area. Also, this study analysed correlation between the established landslide hazard map and the landslide factor effect and reviewed the analysis result of debris flows on the area where landslides with debris flows occurred frequently. Finally;the study proposed ways to renew the established landslide hazard map effectively and utilize the high quality three-dimensional Geospatial information on the landslide risk area.

본 연구에서는 춘천지역을 대상으로 집중호우에 의해 발생된 산사태 및 토석류에 대한 분석을 위해 고해상도 디지털항공사진영상과 항공 LiDAR 자료를 이용하여 생성된 고품질 3차원 공간정보를 활용하였다. 또한 산사태 발생 지역에 대한 기존 산사태 위험등급도와 산사태 관련인자의 연관성을 분석하였으며 집중호우에 의해 토석류를 동반한 산사태 피해가 많이 발생된 지역을 대상으로 토석류의 분석결과를 검토하였다. 이 결과를 이용하여 기존의 산사태 위험지도를 효과적으로 갱신하고 산사태 위험지역에 대한 관리에 고품질 공간정보를 활용할 수 있는 방안을 제시하고자 하였다.
