摘要：Recent progress on Web service technology may provide a solution to current problems in using remote sensing data. This paper presents a prototype geospatial Web service system to demonstrate the advantages of such a system over the traditional non service- based systems for reducing the difficulty of using remote sensing data for research and applications. The foundations of the prototype system are the OGC and W3C standards that define the interfaces for accessing geospatial data and the methods for constructing chainable geospatial Web services. In the system, we have implemented a limited number of interoperable services, including WCSportal, reprojection, visualization, classification, reformatting, subsetting, and georectification. The system allows users to dynamically chain the services with other services and services with data to produce the user-specified products over the Web. The successful implementation of this prototype system will provide us experience in for building large, operational Web systems for geospatial information and knowledge services
