| Abstract: | As the combination of Data Warehouse and Temporal Geography Information System,Spation-Temporal Data Warehouse is a large database designed to support the needs of decision making.The emergence of Spatial-Temporal Date Warehouse extends the scope of applications of GIS and supports the research on global change,development of region.In this paper,Characterizations of Spation-Temporal Data are introduced,and the characterizations and the basic structure frame of Spatial-Temporal Data Warehouse are discussed. |
