摘要
八叉树结构是3DGIS中一种研究和应用最为广泛的栅格数据结构。在对线性八叉树编码方法进行分析的基础上,将行程编码技术引入八叉树的数据压缩,形成三维行程编码方法。并对三维行程编码的八叉树显示方法进行讨论。
Octree is one of the most studied and used raster structures in 3 D GIS. In this paper, linear octree encoding method is introduced firstly, three dimensional run encoding is then developed to compress octree data. Finally some tests are made to confirm the results.
