Organizing Spatio-temporal Data of Land Subdivision with Temporal Land Parcels

In order to model and represent the spatio-temporal processs of land subdivision, a spatio-temporal data model concerning temporal objects is designed in this paper. With the help of three tables:active land parcel, non-active land parcel and future index, and spatio-temporal data of land parcels are maintained in the land-related database and can be accessed by the users even after the land parcels completed their functions. In addition, time is added at two levels:at tuple level and at attribute level.
