文回顾与评述了三维GIS的相关发展情况,探讨了三维GIS的有关基本问题,如数据获取、大数据量存贮与处理、三维空间分析,同时指出科学计算可视化、数据库系统管理、数字影象处理等技术的成熟和二维GIS长期发展提供的理论实践经验等为三维GIS的发展提供了良好的基础。最后为三维GIS实际系统的开发提出了几个值得注意的要点。-In this paper,the review and comment on the development of 3 dimension GIS are first made.Then the basic aspects about 3D GIS,such as data acquisition,storing and processing of mass data,analysis of 3D space,are discussed.Meanwhile, it points out that the techniques such as scientific computation visualization,database system management and digital image processing,and theories and experiences provided by development of 2D GIS offer a better platform form the development of 3D GIS.Finaally,some key points in developing practical system of 3D GIS is proposed.

分形。纹理可以使用分形几何方法(Fracta1 geometry)来真实地描述自然景物,使用过程而不是使用方程来对物体进行建模。正如我们所期望的, 过程描绘的物体其特征远不同于方程描绘的物体。物体的分形几何表示可以用于很多领域, 以描述和解释自然现象的特性。在计算机图形学中, 使用分形方法来产生自然景物显示及各种数学和物理系统的可视化。-fractal. Texture can use fractal geometry (Fracta1 geometry) to describe the beauty of nature, the use of the process rather than the use of equations to model objects. As we had hoped, the process of objects depicted far different from the characteristic equation painted objects. Objects said Fractal geometry can be used in many areas to describe and explain natural phenomena features. In computer graphics, the use of fractal method to generate natural landscape display and mathematical physics and visualization system.
