Development of a Grid GIS Prototype for Geospatial Data Integration

Recently, there has been a fast proliferation of applications creating geospatial data distributed somewhere that has to be processed, queried and analyzed efficiently. Consequently, there is a need for effective data processing technologies that are able to support such distributed query and analysis operations. The emergence of grid computing offers a well solution to accomplish this goal. Development technologies to accomplish grid GIS were derived in this paper. After discussing the structure of grid GIS for geospatial data integration, one actual prototype system was designed and then implemented. Several implementation methods, including global directory construction and global parsing algorithm, were brought forward in this paper. Through the grid system, integration of distributed geospatial data was achieved.
