Abstract |
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. Three relations are defined on events: they are is-a relation, part-of relation, and event-driven relation. We implemented a prototype system, and confirmed that our model is adaptable to searching dynamic aspects of geographic information based on real world phenomena. |
