자연관광자원 관리를 위한 드론매핑시스템의 활용: 신두리 해안사구를 중심으로

Abstract

Coastal sand dunes are sand dunes created on the coast and play an important role in the coastal ecosystem, such as protecting the coastline, habitat for animals and plants, and storage of ground-water. In addition, the coastal sand dunes are very important as natural tourism resources as they are unique desert terrain that cannot be seen in Korea. However, in recent years, coastal erosion due to large-scale reclamation or development has increased the damage of coastal sand dunes, so it is necessary to monitor and manage the coastal sand dunes in time series in terms of protection. In this study, 3D precise displacement analysis was performed to monitor the shape change of the Sinduri coastal sand dunes in terms of natural tourism resource management. To this, the target area was photographed with a drone in 2020 and 2021, respectively, and a three-dimensional point cloud was created and then the topographical change was analyzed in terms of spatial information. As a result, it was possible to analyze topographic changes with cm-level precision, and it was found that a precise 3D topographical model could be created using only low-cost drone images. This means that it is necessary to replace the existing coastal sand dune survey techniques.
