| Abstract(in English) | In this paper, we propose a system for dealing with event-based geographic information to manage changes of spatio-temporal geographic information. Using tuis system, we can deal with changes of geographic information as not only sequential object sets, but also semantic unit. First, we define the event model as a phenomenon that causes changes in geographic information. Second, we define the relations among event objects. There are two relations among event objects: an event-driven relation and a component relation. Event objects have the event-driven relation if one of them induces other event objects. The component relation is defined as the relation between one event object and included event by that event object. Finally, we define the event class, which is used to classify types of event. We implemented a prototype system, in which the changes of geographic involved with consolidation of municipalities are treated. In this system, the changes shown to user are selected based on a set of related event object. From this system, we confirmed the validity of our event model |
