Research on “Visualization and Calculation Integration System of Water Conservancy Project based on VR-GIS
In the traditional planning and designing process of the water conservancy project, there is a serious gap between the project visualization (“Visualization) and the project calculation (“Calculation). Usually, “Calculation can not be guided by “Visualization, and “Visualization can not quickly reflect the result of “Calculation. In order to resolve the disjoint between “Visualization and “Calculation, this article discusses the method of realizing the integration of “Visualization and “Calculation in planning and designing water conservancy project by adopting the technologies of Virtual Reality (VR) and Geographic Information System (GIS). The VR technology can provide a realistic, interactive and dynamic three-dimensional scene of the water conservancy project area by computer technologies. By this three-dimensional scene the analysts will get the immersive feeling even if they are not at the scene. GIS can provide the strong function such as spatial data storage and analysis, three-dimensional terrain analysis, and so on, to address its advantage in “Calculation. So in this article, the threedimensional virtual environment is built to express the terrain, topography and landscape of the project area, and with this three-dimension environment, the hydroelectric reservoir storage capacity, the submerged area and the volume of excavation and filling in the water conservancy project can be calculated.
