A Study of Spatio-temporal Data Model Based on Graph Theory
Yin Zhang · 2003
Several representative spatiotemporal data models are presented. It is difficult to depict and express the spatiotemporal semantics. A graph theorybased spatiotemporal data model is presented. In the model, a vertex depicts an entity, and a border depicts a temporal connection between two entities. This can express entity and temporal connection directly. Finally, the change of land subdivision is depicted with the data model.
