     spatio-temporal data models are the core of a temporal geographic information system (tgis). they define object data types, relationships, operations and rules to maintain database integrity. rigorous data model must anticipate spatio-temporal queries and analytical methods to be performed in the tgis. spatio-temporal database models are intended to deal with real world applications, where spatial changes occur over the time line. a serious weakness of existing models is that each of them deals with few common characteristics found across a number of specific applications. thus the applicability of the model to different cases, fails on spatio-temporal behaviors not anticipated by the application used for the initial model development. this paper reviews the different types of spatio-temporal data models and provides an overview of previous achievements within the domain and critically evaluates the various approaches.
