Research on index technology of high dimensional spatial data

XIA Yu ①,ZHU Xin-yan②(①School of Remote Sensing and Information Engineering,Wuhan University,Wuhan 430079,China;②State Key Laboratory of Information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,Wuhan 430079,China)  
Nowadays the applications of spatial data similarity search are widely needed,and high dimensional spatial data index becomes a key technology of similarity search.Beginning with analyzing the distribution of high dimensional spatial data,this paper discusses high dimensional spatial data retrieval in similarity search.Based on all the research,we propose a method to classify the high dimensional spatial data index technology for similarity search,which initially makes a clear distinction of the relationship between high dimensional spatial data index and similarity search.Then high dimensional spatial data index principle and the state of its applications in similarity search are analyzed with an example of typical index structure respectively,which lays a foundation for the research on index technology in spatial data similarity search.
