Zhihong Xu, Shentu Hai-gang · Geography and Geo-Information Science · 2004
With the economic development, more changes based on land use are happened.The management of spatio-temporal information is brought out as an urgent problem in the cadastral information system.On the basis of the requirement of cadastral management and the theory of event semantics,the spatio-temporal model based on event semantic is brought out in the paper.Five aspects——who, when, where, how and what are used to record changes, and they are managed by five domains——attribute domain, time domain, space domain, event domain and relationship domain.Four examples based on this model are given on historical query, rollback and recurrence.
