摘要：

The Open Geospatial Consortium Web Processing Service specification is intended as a solution for creating and distributing web-based functions. This paper seeks to evaluate the WPS specification with respect to feasibility and utility, to identify areas for improvement, and to provide a demonstration implementation approach including a client-side tool and a server-side wrapping technique for exposing geoprocessing functionality through WPS using an asynchronous approach. Challenges with the WPS specification, some of which are already being addressed in the newest WPS revisions, are discussed together with proposed solutions. Several potential enhancements to the WPS proposal are introduced and considered, including a mechanism to guide client applications in prompting for correct data and a means to list the data available on a server.
