The paper summerized the history of spatio-temporal data model in Temporal Geographic Information System(TGIS),and also analyzed the characteristics of some typical spatio-temporal data models, such as Sequent Snapshots Model, Base State with Amendments Model, Space-Time Composite Model, Space-Time Cube Model, Not First Normal Form(N1NF) Model and Object-Oriented Spatio-Temporal Model. At the end of the paper, the authors presented the necessity of designing object-rational spatio-temporal data model with raster data.
