摘要
Abstract
Threshold method and spectral relationship method are traditional methods for water body information extraction, the two methods, however, could not distinguish cloud shadow from water body,which leads to lower precision. For achieving a optimal model, the K-T transformation (Kauth-Thomas transformation) was applied to the TM image firstly, and then the improved model of water bodies extraction was found using the six new wave bands of the TM image after K-T transformation. It can be concluded that only when the spectral curve of water body occurred with W shape, could the new model of water body information extraction, Greenness <Wetness> Fourth, eliminate the influence of all shadow and extract the water body with higher precision.关键词
