Abstract
Abstract. The volume of real-time streaming data produced by georeferenced sensors and sensor networks is staggeringly large and growing rapidly. Queries on these geo-streams often require tracking spatiotemporal extent (e.g. evolving region) continuously in real time. The notion of real-time monitoring and notification requires support from a database capable of tracking and querying dynamic and transient spatiotemporal events as well as static spatial objects and sending out real-time notifications. In this paper, we leverage the work in data type based spatio-temporal databases and propose new data types called STREAM and their abstract semantics to support geo-stream applications. New operations on STREAM data types are defined and illustrated by embedding them into SQL. 1
