To increase directional query efficiency, based on the study of existing algorithms of directional query, new pruning rules for directional query were given, combined with the new index structure MB-tree. The rules exclude the MBRs outside the query

In the spatial database, the furthest neighbor query is a jumped-up method. If different distances and pruning strategies are properly selected, we can greatly reduce the node number in search space. Through using data cube and edge detection method,

In this paper, an index structure - BR-tree for spatial data , is proposed by combining the division for spatial data objects with bi-tree. In the structure, the topological relations between spatial data objects are recorded and the overlap between
