| Abstract: | 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. |
