| Abstract: | Focus on integration framework architecture design, technology roadmap and key techniques aspects, this paper present the researches conduct on how to realize data interoperability and information integration in process of building large scale GIS service platform. In this paper, it proposed a five-layer-architecture for the integration framework of distributed geospatial information, and declared the conceptual of fundamental geospatial information web services. By raising the distributed geospatial query routing algorithm and virtual quadtree model, it promoted the step to achieve interoperability of spatial information. |
