In spatio-temporal database,geographic entity model includes spatial and temporal information of geographic object.In order to quickly query entity's spatial and temporal information,an effective spatio-temporal index mechanism is needed.On the basis of simply introduction of some spatio-temporal access methods,a new spatio-temporal access method is proposed in this paper: Multi-level grid spatio-temporal index.The algorithm is introduced.
