摘要
选取Landsat8卫星OLI的武汉地区部分遥感影像,采用基于阈值的单波段法、谱间关系法、基于阈值的指数法提取水体影像,结果表明:单波段阈值法的水体提取可以达到89.44%;谱间关系法提取出的水体含有较多的建筑物信息,错分像元较多;基于阈值的指数法中MNDWI精度最高,可作为Landsat8卫星提取水体的重要方法。
Select Landsat8 satellite OLI part of remote sensing images in Wuhan,based on the single band threshold method,the relationship between bands,threshold based index method based on extracting water body image,the results showed that：single-band threshold method of water extraction can reach 89. 44% . The relationship between spectrum method to extract the water contains a lot of building information,more pixels misclassified. The accuracy of MNDWI index method based on the threshold of the highest,an important method for Landsat8 extraction from satellite can be used as water extraction.
