Spatio-Temporal Data Model and Spatio-Temporal Databases

Spatio-temporal database can deal with the objects’ temporal and spatial properties uniformly, and it can manage data that is evolving with time, i.e., the information of spatial objects whose shape and position evolve with time. In spatio-temporal database, spatial data has one more time dimension, which increases the complexity of data management. In this chapter, we first introduce the concepts of spatio-temporal database, and then introduce the spatio-temporal data model, query types of spatio-temporal data and the architecture of spatio-temporal database system.
