A Hybrid Architecture for Implementing Efficient Geospatial Web Services: Integrating .NET Remoting and Web Services Technologies

Open GIS Consortium (OGC) Geospatial Web services have been introduced to overcome spatial non-interoperability problem associated with most geospatial processing systems. Although OGC geospatial Web services provide interoperability among heterogeneous geospatial processing systems, in some cases they can not provide required performance and efficiency. This paper proposes a hybrid architecture which can efficiently provide interoperability and high performance for transferring geospatial data. It is suggested that making use of Web services technologies for implementing OGC geospatial Web services would significantly facilitate sharing geospatial data in heterogeneous environments like Web. In addition, making use of a proprietary and platform-dependant technologies can provide best performance and efficiency in homogeneous environments like an internal network. In this context, design and development of an OGC geospatial Web service using hybrid architecture of Web services Technologies and .NET Remoting technology (as proprietary and .NET specific technology) is described. Based on our evaluations and practical tests, the hybrid architecture proved to be an efficient solution for development of geospatial Web services.
