Distributed geospatial data integration based on OGC standards-compliant geospatial data grid services

Geospatial data is the core of spatial information system. It is always a research hotspot of how to realize the sharing and integration applications of distributed geospatial data. OGC has developed a number of web services specifications that enable the interoperation of heterogeneous geospatial data sources. Grid is the technology enabling resource sharing and coordinated problem solving in dynamic, distributed environment. In this paper, we research on the integration technologies of distributed geospatial data based on OGC standards-compliant geospatial grid services by combining grid and OGC. Firstly, we introduce the OGC Web Services standards and grid technology. Then, we design the framework of integration system of distributed geospatial data based on OGC standards-compliant geospatial data grid services. Lastly, we research the main technologies of distributed geospatial data integration based on OGC standards-compliant geospatial grid services.
