Implementation of Management of Land Temporal Information and Land Parcel Change Process in LIS

At the present time, the database management system of some existing GIS or LIS is able to handle the spatial data efficiently, but these spatial data just describes the current states of entities or phenomena without any information about their past states. In practice, the past states are as important as the current ones for some special applications.A good decision should take the past and current states into account for the future plan.This paper tries to extend the existing GIS or LIS to support temporal information of entities as well as spatial information,and uses an example to show the detail about how to realize the extension and finish the change of land parcels.
