Abstract
Spatial index is the vital technique for improving storage efficiency of spatial databases and the spatial retrieve performance. Traditional technology of index can not be used efficiently in spatial index. This paper classify a series of methods on spatial database index, and introduce the QR-tree index structure with very large spatial database.
