Abstract

In order to advance forest resource management, it is necessary to solve problems such as the aging of forest-related industry workers and the field investigation system centered on manpower. Therefore, in this study, the trend of establishment and utilization of overseas forest geospatial information applied with the latest technology for scientific forest resource management was investigated to identify the domestic application plan. Overseas, photogrammetry and LiDAR technologies were being used to construct and utilize forest geospatial information. In the case of photogrammetry, it was used to measure the volume of vegetation, diameter, and tree height. And LiDAR technology has been applied to the measurement of diameter, and tree height. Through the analysis of overseas cases, it was identified how to construct forest geospatial information using photogrammetry and LiDAR, and it was found that LiDAR showed higher accuracy than photogrammetry. In the future, if the construction of forest geospatial information using various LiDAR sensors are performed and the accuracy and work efficiency are analyzed, it will be possible to present the possibility of using new technologies in the construction of forest geospatial information in Korea.

산림자원관리의 선진화를 위해서는 산림 관련 산업 종사자의 고령화와 인력 중심의 현장조사 체계 등의 문제해결이 필요하다. 이에 본 연구에서는 과학적인 산림자원관리를 위해 최신 기술이 적용된 해외 산림공간정보 구축 및 활용동향을 조사하여 국내 적용 방안을 파악하고자 하였다. 해외에서는 산림공간정보 구축 및 활용에 사진측량 및 LiDAR 기술이 활용되고 있었다. 사진측량의 경우 식생의 체적, 흉고직경, 수고 측정 등에 이용되었으며, LiDAR는 흉고직경 및 수고 측정에 적용된 사례가 있었다. 해외 사례에 대한 분석을 통해 사진측량 및 LiDAR를 활용한 산림공간정보 구축방안을 파악하였으며, LiDAR가 사진측량에 비해 높은 정확도를 나타냄을 알 수 있었다. 향후 다양한 LiDAR 센서를 이용한 산림공간정보의 구축을 수행하고, 정확도 및 작업 효율에 대한 분석이 이루어진다면 국내 산림공간정보 구축에 있어 새로운 기술의 활용 가능성을 제시할 수 있을 것이다.
