The Design and Implementation of a Virtual Sensor Web Platfor Bad Weather Monitoring

摘要

This paper designed and implemented a web-based interoperation architecture for integrating diverse sensor data source for weather application using a service-oriented architecture (SOA). In this architecture, the OGC Data Interoperability Technology and Protocols are applied to provide uniform standard access interfaces. Sensor data will be served through standard OGC WCS (Web Coverage Services), satellite-derived winds, model data and in-situ storm reports will be served by Standard WFS (Web Feature Service). The prototype detection and tracing application are decomposed as several independent logical units (Services) and are published as standard WPS (Web Processing Service). By defining WDSL description for these WPS, they can be easily chained and executed through available BEPL Engines. A unified OGC-Compliant Data Access Component is developed to provide standard access to various sources. This paper presents a promising architecture for web based interoperation system.
