Recently, a lot of researches on geographic information models for handling events have been proposed. However, many of researches are application-oriented. Namely, they are not suitable to represent a phenomenon spreading broadly in the geographic space such as earthquakes, typhoons, and so on. In this paper, we propose a new model for handling events in a distributed geographic information system. In our model, event information and geographic information are represented independently, and they are associated dynamically according to the viewpoint of users for an event.
