| Abstract: | This paper presented a case study on how to integrate virtual reality(VR) technology with geographical information system(GIS) for simulating the soil erosion process in Dongzhen Reservoir of Fujian Province,China.The research work was divided into three parts: (1) building a three dimension simulated environment of the whole reservoir area with remotely sensed image SPOT5 and digital elevation model(DEM) driven from contour relief map;(2) modeling the soil erosion process and visualizing the dynamic process on a computer,and(3) predicting the farther evolution of erosion process via changing the affecting factors and visualizing the future scenario of the reservoir area.Taking Dongzhen Reservoir of Fujian Province as a typical case,the environment condition and basin status around the reservoir area are simulated for display based on the VRGIS technology,the 3D simulation scene of soil and water erosion status and dam is built by the project of water and soil conservation simultaneity.Through this method,combined the integration of flood analysis feature and 3D spatial visual data,using the special function of GIS in spatial data processing and analysis,the unified data and graph of monitoring and predicting system of water and soil erosion is also realized,the scientific characteristic of monitoring and prediction of water and soil erosion is also strengthened,providing a reliable information source for reducing the harm of water and soil erosion. |
