A Dynamic Architecture for Distributing Geographic Information Services Journal Article uri icon



  • Traditional GISystems are no longer appropriate for modern distributed, heterogeneous network environments due to their closed architecture, and their lack of interoperability, reusability, and flexibility. Distributed GIServices can provide broader capabilities and functions for data management, browsing, and exchange. This paper introduces a dynamic architecture for distributing GIServices. The term dynamic indicates that the architecture is constructed temporarily by connecting or migrating geodata objects and GIS components across a network. The intention of the paper is to overview components and protocols necessary for a workable implementation of dynamically linked GIServices. The paper introduces a metadata scheme for both geodata objects and software components, and proposes an implementation framework based on existing languages, computing architectures and web services. In the framework, GIS nodes form the basic processing unit. All GIServices can be accomplished through collaboration between GIS nodes. The design of the presented framework emphasizes scalability, reusability, and dynamic integration. Current distributed computing environments cannot fully support dynamic architectures for technical and other reasons. Throughout the discussion, we distinguish what currently can be implemented from what cannot. We summarize costs and benefits of adopting a dynamic GIServices paradigm in a final section.
