State and event is a pair of basic conception in Temporal Geographical Information Systems (TGIS).Now most of spatio-temporal data models deal with both conceptions separately,and cannot combine the merits of both models.In this paper,a new spatial-temporal data model based on state-event is presented,and the qualifications for conversion between spatial-temporal data models are analyzed.
