摘要
首先分析了大范围有源洪水淹没分析方法的研究现状。然后面向三维虚拟地球应用,基于全球地形数据组织方法,提出了一种以地形瓦片为单元的有源洪水淹没分析算法,实现了三维虚拟地球中的大范围有源洪水淹没分析。最后基于开放式三维虚拟地球集成共享平台软件GeoGlobe进行了实验,验证了该方法的有效性。
In this paper, firstly, the deficiency of traditional large-scale source submergence analysis is introduced. Secondly, considering the application in the 3D virtual globe and based on the global ter- rain data organization method, a terrain tile - based algorithm for source submergence analysis is pro- posed, and the large-scale source submergence analysis is achieved in the 3D virtual globe. Finally, according to the algorithm, a GeoGlobe-based experiment is tested and some advices are discussed.
