Base state with amendments spatio-temporal data model on time-slot retrieval based on temporary base-state

The method of traditional base state with amendments spatio-temporal data model processing slot-time retrieval is simply extended from time-point retrieval, neglected the characteristics of the adjacent of each point-time. This paper proposed the concept of temporary base-state, which set the current retrieved time as temporary base-state and the next point-time select the operation of base-state, having less operand between the temporary base-state and fixed base-state.
