A Geographic Event Management, Based on Set Operation Among Geographic Objects
説明
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 an event spreading broadly in the geographic space, such as earthquake, typhoon, and so on. In this paper, we propose a new model for geographic information system. In our model, event information and geographic information are represented independently, and are associated flexibly from a viewpoint of users for an event.
