Integration with spatiotemporal relationship operators in SQL
Jong Yun Lee, Kwang Jin Oh, Keun Ho Ryu · 1998
Spatial objects in the world and location data for the vehicle change their spatial or non-spatial data over time.We therefore propose a spatiotemporal database schema and its operations to support all their history management and integration of spatial and temporal operations in a uniform manner.They will be implemented by extending time dimensions and time comparison operators in a geographic ~ormation system(GIS).Finally, we believe that our proposed spatktemporal database provides a usefhl tia.mework for history management of tirnevarying location data of vehicles and spatial objects in the world.
