Abstract

Abstract: Taking the Nanjing city as the research area, we transform the TM image with the LBV way to extract the water information based on object-oriented classification method. The experiment results show that the extraction accuracy of water information reaches 94.6%. This method not only removes the influence of the mountain shadow and city buildings, but also reduces the salt-phenomenon. This method is simple and has practical value. It is suitable for automatic extraction of water information.

Key words: LBV transformation, object-oriented method, multi-segmentation, extraction of water, MNDWI
