Abstract
With the spread of Geoweb, people can more easily create and exchange geo-spatiotemporal contents on the Web. Consequently, it becomes an emerging issue to manage exploding amount of Geoweb contents more efficiently than traditional approaches for mapping contents on a digital earth and/or a time line. In this paper, we propose a novel approach for managing Geoweb contents based on the idea of moving phenomena such as a typhoon and price escalation. Our moving phenomenon DBMS defines data types and predicates of moving phenomena, and the visual query interface, called Sticker, allows users to aggregate Geoweb contents with 3D view of the moving phenomena. Our framework works well for obtaining comprehensive knowledge about the situations or influences of real-world phenomena from the Geoweb contents.
