摘要
利用搭载在EOS-Aqua/Terra卫星上的MODIS数据,对长江口溢油、委内瑞拉的马拉开波湖溢油等4次事故进行光谱分析和研究。在对出事海域的卫星数据进行图像处理的基础上,利用MODIS数据的多光谱信息,分析溢油在各个波段的特征,并确定油膜特征比较明显的波段范围,为可见光/近红外卫星监测溢油提供参考。
With EOS/MODIS data, the spectrum analysis was carried out for the four oil spill cases which happened in the Yangtze estuary （China）, Lake Maracaibo （Venezuela） and so on. Based on the image processing of the MODIS data, the spectrum feature of different bands was analyzed. It seems that the IR band （1000nm^2000nm） is the better choice for the oil spill detection. The ratio of visible band and 7th infrared band enhances the contrast between oil spill and surrounding water which can be used to detect oil spills with visible/IR sensor in the future.
