The expression of link information between updating data and history data is still a difficult issue so far. This paper proposes a way to identify and store the feature changing information caused by data updating process based on the consideration of features-changing process. Besides
this paper designs the record structure of changing information and verifies the method by real data in a prototype system. The experiment results show that the improved method has better performance in the process of geometric history data backdating and recording of geographic object life cycle.
