A series of multispectral high-resolution Korean Multi-Purpose Satellite (KOMPSAT) images were analyzed to detect the geographical changes in four different tidal flats in the west coast of South Korea. The method of unsupervised classification was used to generate a series of land use/land cover (L...

무감독 분류이란? | 무감독 분류는 영상자료에 대하여 표본자료와 같은 사전정보 없이 파장별, 공간별 특성에 의해서 분류하는 방법으로, 최소한의 입력자료로부터 군집화(Clustering)가 시작되어 분류되는 등급별(Class)로 평균과 공분산을 선택하여 계산된다. 분류하고자 하는 모든 지표 대상물은 빛의 반사 및 흡수 등으로 인해 각 파장에 대해서 고유한 밝기 값을 나타내기 때문에 같은 종류의 지표 대상물은 비슷한 분광반사 패턴을 가지게 된다(Sohn and Rebello, 2002). | |
연안 습지를 황폐화시키는 요인은? | 연안 습지는 조석변화와 같은 해양 환경 변화뿐 아니라 대규모의 매립과 도시화 같은 지역개발 활동으로 인해 계속 변화하고 있으며 이러한 변화는 연안 습지를 황폐화시키는 요인이 되기도 한다(Syphard and Garcia, 2001; Baker et al., 2007). | |
공중사진을 이용한 전통적인 방법의 한계를 극복하기 위해 장려되는 방법은? | , 2004). 이러한 한계성 때문에 최근에는 시간과 비용이 적게 소요될 뿐 아니라, 정확한 지리 정보와 함께 높은 시간적 범위에 따라 해안 습지를 조사하고 모니터링 할 수 있는 위성 이미지를 통한 다중 스펙트럼 원격 감지의 적용이 장려되고 있다(Ozesmi and Bauer, 2002; Davrache et al., Nyarko et al. |
