基于MODIS图像海岸带二类水的提取
Determination of Case Ⅱ Water from Coast Zone Using MODIS Image
-
摘要: 提出了一种利用MODIS图像提取二类水的经验算法,该算法是利用一类水和二类水在可见光区的表观反射率差别很大,而在近红外波段的表观反射率基本相同的特性来完成的。利用该算法对不同地区的海岸带进行了二类水的提取,并对其结果进行了讨论。Abstract: An empirical algorithm is described,which is used to determine the case Ⅱ water from the MODIS image.The algorithm takes advantage of the characteristic that the apparent reflectance of the Case Ⅰ water and the Case Ⅱ water is same in SWIR band,but is considerably different in visible band.
