Abstract

Geoparks are worth preserving in an environmentally and heritage. Monitoring and public attention are essential for the conservation and protection of geoparks. The use of Unmanned Aerial Vehicles and the Structure from Motion algorithm enables effective monitoring of geoparks that are difficult to manage due to their wide range of manpower, and various spatial data derived from SfM can be utilized to improve awareness of geoparks that have been lacking. In order to prove this, firstly, we created the 3D spatial data by using the UAV and the SfM algorithm, which is one of the National geoparks of the Hantan-Imjin River area. Using this 3D data for Virtual Reality and 3D printing. After that, we verified the possibility of promoting the geopark through a simple online survey. Finally, we propose a method to utilize all the generated data from each step to promote and research for geoparks.

지질공원은 환경적 측면이나 유산적 측면으로도 보존가치가 높다. 이러한 지질공원의 보존과 보호를 위해서는 모니터링과 국민적 관심은 필수적이다. 무인항공기와 SfM 알고리즘의 활용은 인력대비 넓어 관리가 어려웠던 지질공원의 효과적인 모니터링을 가능하게 해주며, 이로부터 파생되는 다양한 공간정보 데이터는 부족했던 지질공원 인지도 향상을 위해서도 활용이 가능하다. 우리는 이를 확인하기 위하여 한탄-임진강권역 국가 지질공원중 하나인 화적연을 사례로 하여 무인항공기와 SfM 알고리즘을 이용하여 3차원 공간데이터를 생성하여 화적연을 측량하였다. 그리고 이 데이터를 가상현실과 3D 프린팅에 적용하고 간단한 온라인 설문조사를 실시하여 지질공원 홍보 가능성을 확인하였다. 최종적으로 지질공원 모니터링을 목적으로 생성된 각 단계별 데이터들을 조사하고 지질공원의 홍보 및 연구를 위한 교차활용방안을 제시하였다.
