Study of new P2P spatial indexing network on vector data
一种新的P2P空间矢量数据索引网络的研究*

In allusion to the insufficiency of current P2PGIS researches in space vector data index of multi-scale and multi-la-yer,this paper proposed a new P2P spatial indexing network on vector data in view of practice. This network expanded the existing hybrid indexing network architecture, and built the distributed quad-tree which fused multi-scale using pyramid technology. In addition,this paper proposed a query algorithm for distributed P2P spatial vector data, and analyzed the performance of the algorithm by mathematical method. The testing result of the prototype system shows that the indexing network can reduce network burden and improve indexing efficiency effectively.
