LOU Shu-rong,MENG Ling-kui,HUANG Chang-qing(School of Remote Sensing and Information Engineering,Wuhan University,Wuhan 430079,China)  
In this paper,it reviewed the P2P-based spatial data indexing methods.The current P2P spatial data indexing methods was divided into four main categories: the methods based on distributed hash table,tree structure,delaunay triangulation and spatial distance.Then,the research including search methods,load balancing methods and maintenance methods and other relevant technologies was discussed separately for each class in detail.Comparison was performed between query efficiency,maintenance costs and load balance.Finally,this paper was summarized further.
