In spatial database application,to solve the problem that a single special indexing structure constrains retrieval performance with the increment of the amount of data,a hybrid tree special indexing structure is proposed,and so is OR*-tree,which is based on Octree and R*-tree in 3D GIS.
方法提出一种三维GIS中基于八叉树和R*树的混合树空间索引结构OR*树,该结构在对三维索引空间进行八叉划分的基础上应用R*树索引技术,将操作空间限定在某一特定的区域。
