Study of Spatio-Temporal data model in Parcel-alteration and Tracing of history

摘要：

Temporality is the distinct attribute of cadastral information.It is very important to scientifically and efficiently manage three kinds of data that exist in the Cadastral Information System,such as spatial data,temporal data and attributive data.Based on the research of TGIS and the advantages of existing spatio-temporal database model.This paper proposes a design of a spatio-temporal cadastral database which is divided into historical database and alterative database.This design fulfills the requirements for management of cadastral data and reduces data redundance and enhances the efficiency of database.
