摘要
以南京市TM遥感影像为例,利用HOT最优云监测变换方法对遥感影像进行薄云的去除,然后通过分析典型地物在不同波段的光谱特征,引入多波段组合(TM2+TM3)/(TM4+TM5)并辅以单波段(TM5)阈值的方法对南京市的水体信息进行了提取。
Taking TM data in Nanjing as an example,the method of HOT optimal cloud monitoring transformation was firstly used to remove the haze in remote sensing data.And then the information about water in Nanjing was extracted using the method of combination of multiple bands((TM2+TM3)/(TM4+TM5)) combined with a single band(TM5) through analyzing spectral characters of typical objects at different bands.
