In this paper, we propose a data model to manage dynamic aspects of geographic information. In our model, a geographic change is represented as an event.

We implemented a prototype system, and confirmed that our model is adaptable to searching dynamic aspects of geographic information based on real world phenomena. Key words: GIS, Data model,Event
