A spatiotemporal database is a new type of database system that manages spatiotemporal objects and supports corresponding query functionalities. A spatiotemporal object is a kind of object that dynamically updates spatial locations and/or extents along with time. A typical example of a spatiotemporal object is a moving object (e.g., a car, a flight or a pedestrian) whose location continuously changes. Spatiotemporal databases have many important applications such as Geographic Information Systems, Location-aware Systems, Traffic Monitoring Systems, and Environmental Information Systems. Due to their importance, spatiotemporal database systems are very actively researched in the database domain. Interested readers are referred to  for a detailed survey of spatiotemporal Databases.
