| Abstract: | High resolution DEM is created based on original topographical maps of reservoir area. After the quality of DEM is approved reliable, topographic factors analysis, visibility analysis and reservoir volume are achieved based on DEM, to obtain and display water information, 3-dimensional visualization system is designed by combining ASP and VRML. |
