Description: The use of three-dimensional Earth subdivision grid generation SubdivisionR_ tree indexes for multi-dimensional data model redundancy management octree index, R- tree indexes insertion and deletion process complex issues, relying GeoSOT Earth perspective subdivision grid, proposed a Subdivision R- tree indexes new model octree and R- tree organic combination (Subdivision R-tree). First, the Earth' s perspective GeoSOT octree subdivision grid based index constructed Subdivision R- tree indexes model structure subsequently, the basic design of the insertion Subdivision R- tree indexing model, delete, query, analysis algorithm and finally, to carry out Subdivision R- tree indexes with the original data indexing performance comparison test, and the threshold Subdivision R- tree analysis of selected accordingly.
