The Index Storage Model for Urbanization Data Combined Query

摘要：

　　Urban information is a kind of multi-sources data,the paper is focused on data indexes construction,classified indexes for non-spatial data,R-trees index for spatial data and the paper puts forward an area hiberarchy index tree structure to build up direct relationship between spatial data and non-spatial data for combined queries,and the experiment shows that the hiberarchy index tree is much validated and something useful is obtained.
