摘要：Remote sensing and digital elevation model data are all important data sources in the research on geographical information. Geographical information system has the ability of providing powerful functions to support our research. However, we found it was difficult to study water system in plain area by routine methods because the topography is too flat. A method for analyzing the surface water system in plain area with the help of remote sensing, geographical information system and digital elevation model was given in this paper. Based on remote sensing images and the vertical exaggeration of digital elevation model, it was discovered that the relationship between the distribution of water and digital elevation model could provide the evidence for the cause of water system formation and the process of water system evolvement
