Web Processing Service ( WPS ) Orchestration A Practical Approach

The overall experience of any geospatial processing environment depends on the successful collaboration of different distributed components, such as clients, web portals, multiple processing-nodes and service discovery-measures. Many aspects of web service based geospatial processing have already been tackled and put into action at various operational levels and by different means. This contribution provides a brief review of conducted research and work done in the past. It continues with demonstrating a concept for workflow composition based on local and distributed processes. Therefore a domain-specific language is introduced and the field of application demonstrated by an accompanying use case. The overall concept is evaluated using the framing project RichWPS.
