The integration of cross-organizational geospatial services, which are different standard interfaces, is one of problems that limit the use of such orchestration technology as BPEL for assembling geospatial services into a complex geospatial workflow. Because that geospatial services can be implemented over a number of standards and technologies that meet their requirements such as Web service, OGC Web service, or REST. In this study, the necessity and requirements of interface independent orchestration are addressed. The orchestration language is also designed response to interface independent orchestration purpose. Then multi-standard service interfaces over HTTP protocol can be assembled without the need of mediator (such as interface wrapping service). The language interpreter and execution, so called orchestration engine, is implemented behind OGC Web processing service for demonstrating the interface independent orchestration by client requests an execution. Site selection use case in which common problem of GIS projects are selected and used to define an example of orchestration script that contains a sequence of processes with different service interface standards. The result of execution is displayed with verified that cross-organizational geospatial services which is a different service interface, can be orchestrated through the implemented engine. For this solution, open geospatial information services from public organizations and authorities in which different service interface can be orchestrated without the need of mediator implementation.]]>Alameh, N.,2003Amirian, P. and A.
