Analysis on Reservoir Submerging Simulation in the Planning of Villages and Towns

WANG Zi-jun et al(College of Geo-exploration Science and Technology,Jilin University,Changchun,Jilin 130026)  
[Objective] The aim of the research was to provide decision supports for the planning of township and town region.[Method] Taking Luxiang town as a case,DWG topographic map was used to draw elevation information and set up DEM. The fusion image of SPOT-5 with high resolution and multiple-spectrum were prepared as terrain texture to generate three-dimensional image and make reservoir submerging analysis and three-dimensional flying simulation.[Result] The submerged regions were made through human-machine interaction calculation by using VR GIS technology and reservoir submerging calculation model to make planning of the infrastructure and land layout in Luxiang town.Considering synthetically with combination of the characteristics of Luxiang town region,through aerial dynamic observation,analysis and research on the panorama and details of essentials such as landform,physiognomy and vegetation coverage in Luxiang town by three dimensional flying simulation,Luxiang town could be located as characteristic agricultural town with the majority of natural zoology and deer culture in the suburb of Changchun city.[Conclusion] Based on image data of DEM and SOPT5,virtual reality technology was used to make into lifelike three-dimensional visualized flood submerging landscape,which provided decision support for the update,development and planning of villages and towns.
