A distributed geospatial infrastructure for Sensor Web

One of the critical components in developing a Sensor Web is to build a geospatial information infrastructure, a backbone that connects the heterogeneous in situ sensors and remote sensors over the wired or wireless networks. We, firstly, introduce the revolutionary concept of the Sensor Web and provide a comprehensive study of Sensor Web. Secondly, we describe the architecture of a distributed geospatial infrastructure for Sensor Web--GeoSWIFT Sensing Services, which serves as a gateway that integrates and fuses observations from spatially referenced sensors. Thirdly, we demonstrate the prototype of GeoSWIFT Sensing Services that integrates an existing sensor network of webcams into the Sensor Web.
