Wetland is a versatile, rich biological diversity ecosystems on the planet which is one of the most important living environment of human beings. As the representative data of mid-resolution data, ETM data is widely used in Resources survey by its unique advantage in band set. Based on the analysis of water, terrestrial vegetation and aquatic vegetation's spectral characteristic, this article uses ratio composite method (ETM band3/band5(R)、band2/band4(G)、band3/band7(B) to enhance water and wetland information combining with the band characteristics of ETM data. Practice has proved that this method has unique advantage in enhancing water and wetland information, and can improve the accuracy and efficiency in automatic Extraction of wetland information.
