This paper addresses a geographic information management to model various kinds of geographic objects with respect to the space and time features. In this model, an event represents the geographic situation in which geographic objects change, and represented as a set of geographic objects which are concerned to the event. It is possible to easily divide an event into sub-events along space and time criteria. Using this model, our geographic information system can provide users with a capability to manipulate an event from various viewpoints.
