2017~2020년의 4개 클래스가 포함된 이 데이터 세트의 최신 버전은 JAXA/ALOS/PALSAR/YEARLY/FNF4에서 확인할 수 있습니다. 전 세계 25m 해상도 PALSAR-2/PALSAR SAR 모자이크의 SAR 이미지 (백스캐터링 계수)를 분류하여 강한 백스캐터링 픽셀과 약한 백스캐터링 픽셀을 구분하여 전 세계 산림/비산림 지도 (FNF)를 생성합니다. … alos alos2 분류 eroc forest forest-biomass -
전 세계 4등급 PALSAR-2/PALSAR 숲/비숲 지도
전 세계 산림/비산림 지도 (FNF)는 전 세계 25m 해상도 PALSAR-2/PALSAR SAR 모자이크에서 SAR 이미지 (후방 산란 계수)를 분류하여 강한 후방 산란 픽셀이 '산림'으로, 낮은 후방 산란 픽셀이 '비산림'으로 각각 할당되도록 생성됩니다. 여기서 '숲'은 다음과 같은 자연 숲으로 정의됩니다. alos alos2 분류 eroc forest forest-biomass -
