摘要
本文在对三维（３Ｄ）ＧＩＳ中多种数据结构进行分析的基础上，发展了三维行程编码方法，完善了有关四面体格网的理论和算法，提出了一种基于八叉树和四面体格网的混合数据结构，以及基于混合数据结构的３ＤＧＩＳ概念。
In this paper, after an analysis of data structures in 3D GIS, three dimensional run length encoding method is developed and the theory and algorithms of tetrahedral network(TEN) are completed. A hybrid data structure based on Octree and TEN is presented. The concept of 3D GIS based on hybrid data stucture is introduced. Finally, some experiments are made to prove the results.
