  Abstract

Spatial objects in the space world have been changed by either non-spatial operations or spatial operations. For example, their states are changed by the following operations changing their owners, changing their owner's address installing new constructions, changing precincts, splitting, and merging. The conventional geographic information system(GIS), however, did not also manage their historical information because it handles the snapshot image of spatial objects in the world. In this paper we therefore propose a spatiotemporal data model which is able to not only manage the historical information of spatial objects but also support their historical interrogation by extending a time dimension and a historical pointer for SDE(Spatial Database Engine) spatial data model. Finally, the proposed spatiotemporal data model using a layered time extension are going to contribute to manage the history of spatial objects in the world and retrieve them.
