연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

지상라이다의 활용성 검증을 위하여 지상라이다를 이용하여 산불피해지의 임목 피해특성 조사 결과를 전문가에 의해 조사한 결과와 비교하였다. 조사구는 산록에서 산정으로 30 m×50 m(0.15 ha) 규모로 4 plots를 설정하였으며, 조사구내 피해임목의 흉고직경, 수고, 지하고, 지하고, 연소높이 및 수관길이를 조사하였다. 동시에 지상 레이저 스캐너를 이용하여 조사구내 피해임목의 피해특성 정보를 조사하여 전문가 조사결과와 비교분석 하였다. 전문가 조사와 라이다 조사의 비교 결과, 흉고직경은 30.8 cm, 29.7 cm, 수고 15.8 m, 17.5 m, 지하고 8.4 m, 8.4 m, 연소높이 4.0 m, 3.5 m, 수관길이 7.4 cm, 9.1 cm로 나타났다. 두 조사 방법 간에는 수고와 수관길이를 제외한 나머지 조사항목에서는 유의적인 차이를 보이지 않았다. 또한 개체목의 안정성과 고사율에 영향을 미치는 H/D율과 CL/H율, BH/CL율을 분석한 결과, 전문가 조사 51.3%, 47.1%, 53.6%, 라이다 조사 58.8%, 52.0%, 38.7%로 나타났다.

Abstract AI-Helper 아이콘AI-Helper

To verify the field-effectiveness of Terrestrial Laser Scanner (TLS), a terrestrial LiDAR was deployed to examine the damage properties of woods in forest fire area, then the data was compared with the results surveyed by a forestry expert. Four sample plots (30 m × 50 m, 0.15 ha) were set from...
