| 摘 要： | 随着GIS应用的不断深入，以二维方式处理三维地形空间数据已不能满足实际应用的需求．用户需要三维可视化、动态交互地分析、处理、显示多种地理相关数据。同时，随着计算机图形技术的发展，三维仿真逐渐完善，三维表示的地形较之平面地图有更多的优越性．体现了地形三维化的趋势。

| Abstract: | With the continuing development of the application of GIS,the former methods which deal with three-dimensional terrain data in 2D manner,couldn't meet the needs of practical applications any longer. Users want to analyze,process and display the geographic information in manner of dynamically interactive three dimensional(3D) visualization. At the same time,with the development of computer graphics technology,3D simulation gradually improves,3D figure of terrain has more advantages than plane map. Manifested... |
