A Study on tieoSensor Data Stream Processing Techniaue for u-GIS Computing Services

In ubiquitous spatial computing environments, GeoSensor generates sensor data streams including spatial information as well as various conventional sensor data from R F ID ，W SN , W eb C A M , Digital Camera, CCTV, and Telematics units. This GeoSensor enables the revitalization o f various uDiquitous U S N technologies and services on geographic information. In order to service the u-GIS applications based on GeoSensors, it is indispensable to efficiently process sensor data streams from GeoSensors o f a wide area. In this paper, we propose a GeoSensor data stream processing system for u-GIS computing over real-time stream data from GeoSensors with geographic information. The proposed system provides efficient gathering, storing, and continuous query processing o f GeoSensor data stream, and also makes it possible to develop diverse u-GIS applications meet each user requirements effectively.
