Abstract  

There are many extraction methods based on TM images for getting water body information.However,most of them fail to eliminate the influence of shadow of mountain or building fast,accurately and objectively.The paper discussed and verified several commonly used extraction methods.Based on the Munsell HSV color transformation,a new model of water body information extraction (WEM: TM2-TM5>0 and Sat-Va>0) was established.It was testified that by WEM the influence of shadow can be eliminated thoroughly and accurate information of water body can be obtained.
   

Key words:          Munsell HSV transformation      Water body extraction      TM
