Abstract

Dam is built to supply water necessary for life stably and reduce the damage caused by heavy rains. Recently there has been required the analysis and utilization of spatial information on the area around the dam because construction of the dam gives a great impact on the environment of the surrounding area. In this study, we build spatial information about the submerged district due to dam construction using drone and propose the effective method for analysis of the spatial information. As a result, orthoimage and DSM of study area were constructed effectively. Change of submerged district of this area was calculated according to the analysis of spatial information. Building and analyzing spatial information carried out in this study are expected to be utilized as the basis in related fields.

댐은 생활에 필요한 수자원을 안정적으로 공급하고, 집중호우에 의한 피해를 저감하기 위해 건설된다. 댐의 건설은 많은 토지, 가옥 등이 수몰되고 주변지역의 환경에도 큰 영향을 주기 때문에 최근에는 댐 주변지역에 대한 공간정보의 분석 및 활용이 요구되고 있다. 이에 본 연구에서는 무인항공기를 활용하여 댐건설로 인한 수몰지역에 대한 공간정보를 구축하고 효과적인 공간정보 분석 방안을 제시하고자 하였다. 연구를 통해 댐 및 주변지역에 대한 정사영상과 DSM의 공간정보를 효과적으로 구축할 수 있었다. 또한 DSM에 대한 분석을 통해 댐의 담수에 따른 침수 지역의 변화와 수량을 효과적으로 산정할 수 있었다. 무인항공시스템을 활용하여 공간정보를 구축하고, 이에 대한 분석을 기반으로 효과적인 댐 주변지역의 관리 방안 제시할 수 있었으며, 연구에서 수행된 공간정보 구축 및 분석방법은 관련 분야의 기초자료로 활용이 기대된다.
