Abstract

Forest investigation is the basic data for forest preservation and forest resource development, and periodical data acquisition and management have been performed. However, most of the current forest investigations in Korea are surveys to grasp the current status of forests, and various applications have not been made as geospatial information. In this study, the unmanned aerial scanner was used to acquire and process data in the forest area and to present an efficient forest survey method through analysis of the results. Unmanned aerial scanners can extract ground below vegetation, effectively creating DEM for forest management. It can be used as geospatial information for forest investigation and management by generating accurate topographical data that is impossible in conventional photogrammetry. It can also be used to measure distances between power lines and vegetation or manage transmission lines in forest areas. The accurate vertical distance measurement for vegetation surveys can greatly improve the accuracy of labor measurement and work efficiency compared to conventional methods. In the future, the use of unmanned aerial scanners will improve the data acquisition efficiency in forest areas, and will contribute to improved accuracy and economic feasibility compared to conventional methods.

산림조사는 산림보전 및 산림자원개발을 위한 기초자료로 주기적인 데이터 취득과 관리가 이루어지고 있다. 하지만 현재 우리나라의 산림조사는 단순한 산림의 현황을 파악하는 조사가 대부분이며, 공간정보로서 다양한 활용이 이루어지지 않고 있다. 본 연구에서는 무인항공 스캐너를 이용하여 산림지역의 자료취득 및 처리를 수행하고, 성과물의 분석을 통해 효율적 산림조사 방안을 제시하고자 하였다. 무인항공 스캐너는 식생 하부의 지면을 추출할 수 있기 때문에 산림지역 관리를 위한 DEM을 효과적으로 생성할 수 있으며, 기존의 사진측량방법에서 불가능한 정확한 지형 데이터의 생성으로 산림조사 및 관리를 위한 공간정보로써 활용이 가능하다. 또한 산림지역에서 전력선과 식생간의 간격 측정이나 송전선로 관리에 이용될 수 있다. 식생의 조사를 위한 정확한 연직방향의 거리 측정이 가능하기 때문에 기존 방법에 비해 수고측정의 정확도 및 작업의 효율성을 크게 향상시킬 수 있다. 향후 무인항공 스캐너의 활용은 산림지역에서의 데이터 취득 효율성을 향상시킬 것이며, 기존의 인력에 의한 조사에 비해 정확도 개선 및 경제성 확보에 기여할 것이다.
