Temporality is the basic attribute of cadastral information.It is very important to scientifically and efficiently manage all kinds of data that exist in the Cadastral Information System(CIS),such as spatial data,temporal data and attributive data.Based on the research of TGIS and the advantages of existing spatiotemporal database model,this paper proposes a design of a spatiotemporal cadastral database which is divided into up-dated database,historical database and alterative database.This design fulfills the requirements for spatial,temporal,spatiotemporal queries for cadastral data,and reduces several existing database and enhances the efficiency of database.It is supposed to be helpful for the research of TGIS in CIS.
