四叉树空间索引技术在江苏电网GIS中的应用研究

Research on the Application of Quadtree Index in Jiangsu Power Grid GIS Platform

为了解决江苏电网GIS并发更新时间长的问题,文章分析了在图形数据变更场景下,四叉树空间索引与R树空间索引的技术特点,结合江苏电网GIS实际业务场景需求提出四叉树空间索引改造方案,最后通过实验测试及实际运行验证了四叉树索引在电网GIS图形数据变更场景下的有效性。

To solve the problem of the concurrent update time consumption of Jiangsu power grid GIS platform, this paper analyzed the technical features of Quadtree index and R-tree index in the context of graphical data changes. Considering the actual business scenario requirements of Jiangsu power grid GIS, this paper presented a scheme of Quadtree spatial index transformation. The experimental results and the actual operating results showed the efficiency of Quadtree index in the case of the GIS platform graph data change.
