A Spatial Index Based on Clipping Bounding Box of Space Partitioning Tree [PDF]
In spatial databases, spatio-temporal indexes based on R tree use minimum bounding box(MBB)to approximate spatio-temporal data to improve query efficiency, and the efficiency of indexing can be further improved by by clipping the bounding box.To ...

Modeling and Querying Multi-dimensional Moving Objects
Motivated by the problem that the existing spatio-temporal data models do not fully represent moving objects, we design a multi-dimensional data model supporting multiple attributes, static and dynamic attributes.
