摘要
介绍了利用遥感图像生成DEM和地形可视化的过程 ,同时介绍了基于VRML的Web虚拟现实技术 ,最后举例来说明如何实现对遥感数据的DEM地形可视化并利用VRML来实现在Web中的发布 ,并给出了单机模式下和Web模式下的DEM生成耗时性能对比表。
This paper introduces the process of using remote sensing image data to produce DEM and visualization. Meanwhile it introduces how to use VRML to achieve Virtual Reality based on the Web. At last it gives the sample of how to process the visualization and release it on the Web, also it gives the contrast table of cost time between the stand alone model and the Web model.
