摘要
基于DEM数据和遥感影像结合实现三维地形可视化的技术,阐述了所用GIS数据的处理方法与过程,提出了一种实时动态生成小范围地区三维地景的轻量级算法。模拟了山西省太原市某点周围的三维地形景观,在此基础上探讨了ArcGlobe平台下优化显示性能的几个措施,最后指出这种算法的应用场合。
The methods and processes of processing GIS data were presented firstly, a light-weight algorithm was proposed that creats 3D terrain landscape dynamically in real-time for a small area in terms of technology of 3D terrain visualization combined DEM data with remote sensing imagery. The 3D terrain landscape of a position together with the area around the point of Taiyuan in Shanxi province was simulated. How to optimize the display performance was dicussed on the basis of the simulated results, and the applied situation of this algorithm was indicated at the end.
