Abstract

How to use web services quickly and efficiently is quite important in geospatial applications. A possible solution of sharing and integrating geospatial resources in opening web environment is to chain distributed and diversified geodata and geoprocessing by using web services. This paper presents an approach for chaining geoprocessing by employing Web Processing Service (WPS) and Business Process Execution Language for Web Services (BPEL4WS) under the service-oriented architecture (SOA) and Open Geospatial Consortium (OGC) standard. Workflow control model and SQL Server based register center are used in a prototype system for chaining geoprocessing web services which have been performed functionality decomposition and packed by using extended WPS.
