星载多光谱浅海水深测量方法

Method of Satellite-borne Multispectral Bathymetry in Shallow Water

利用遥感技术以及星载多光谱数据,进行浅海海域水深测量的基本方法以及关键技术,提出了一种基于主成分分析方法和底质分类的新的浅海水深提取技术路线,可应用于浅海水深提取及海图制作和更新.

Using remote sensing technology and satellite-borne multispectral d ata,the basic methods and key techniques to measure the water depth in shallow water are discussed.A new technology flow of exacting the depth in shallow water based on primary component analysis(PCA)and bottom classification is put forw ard to be applied in making or renewing ocean cartography.
