Spatiality, temporality, legality, accuracy and continuality are characteristic of cadastral information, and the cadastral
management demands that the cadastral data should be accurate, integrated and updated timely. It's a good idea to build
an effective GIS management system to manage the cadastral data which are characterized by spatiality and temporality.
Because no sound spatio-temporal data models have been adopted, however, the spatio-temporal characteristics of
cadastral data are not well expressed in the existing cadastral management systems. An event-version-based
spatio-temporal modeling approach is first proposed from the angle of event and version. Then with the help of it, an
event-version-based spatio-temporal cadastral data model is built to represent spatio-temporal cadastral data. At last, the
previous model is used in the design and implementation of a spatio-temporal cadastral management system. The result
of the application of the system shows that the event-version-based spatio-temporal data model is very suitable for the
representation and organization of cadastral data.
