The Spatiotemporal Schema for Geographic Information Systems
Morishige Ota · Theory and Applications of GIS · 1999
The data models for GIS are usually static. In those cases, the geographic features cannot move nor mutate. However, the phenomena in the real world commonly have such a characteristic that they are changed among time and be succeeded to the next generations. This paper starts from the definition of the persisten 2D schema. And, the temporal static primitives are introduced. Then, the spatiotemporal schema which can describes the motion (movement and deformation) is suggested. Finally, the simple examples applying these schemas are introduced.
