分析了四叉树空间索引的优缺点,提出了一种可扩展的线性可排序四叉树空间索引,实现了空间索引的动态更新,同时具有高效的空间查询能力。
After analyzing the advantages and disadvantages of quadtree spatial index,we present an extensible linearly sortable quadtree spatial index.This method makes the spatial index updated dynamically,and has high spatial query efficiency.
