Temporal geographic information systems(TGIS) aim to represent,manage and analyze the dynamically changing geographic phenomena.Spatio-temporal database is the core of TGIS,and its theoretical foundation is spatio-temporal data model,so the research of spatio-temporal data model is very essential.The presented spatio-temporal data models include simple models,space-time joint models,space-time-attribute three-domain models,object-/feature-based models and event-/process-oriented models,et al.This paper reviewed these models,analyzed and compared their advantages and disadvantages and emphases.Furthermore,pointed out the future research directions on spatio-temporal data models.
