An Integrated Spatio-Temporal Data Model
Hao Wang · 2009
As a difficult problem in theory and technique of GIS,temporal GIS gets more and more attention,and the study emphasizes on the design and implementation of spatio-temporal data model.Aiming at some issues of spatio-temporal data model,an integrated spatio-temporal data model was proposed.There were five kinds of integration,which included the integration of static state and temporal state,the integration of vector data and raster data,the integration of topological data and non-topological data,the integration of geometry data and attributive data,and the integration of discrete change and continuous change.Finally,the model was applied in our own experiment system,and some experimental were done with patch data,vehicle track data,and cloud image of meteorological satellite.The results showed that the proposed model was reasonable and feasible.
