Research on hybrid-integration of multisource spatial data based on ArcSDE and Socket

MENG Ling-kui,ZHOU Yang,Li Ji-yuan,ZHU Chang-xian(School of Remote Sensing and Information Engineering of Wuhan University,Wuhan 430079,China)  
With the rapid growth of heterogeneous spatial information resources,how to integrate and manage multisource spatial data efficiently in GIS system has become one of the key points and difficulties in GIS.Firstly,several main multisource spatial data integration methods were analyzed and studied in the paper.Drawing on their advantages and combining with the real-time feature in spatial data application,it proposed a new solution that managed real-time spatial data with hybrid-middleware,which mixes with both ArcSDE and Socket communication mechanisms,provided non-real-time spatial data service with ArcGIS Server,finally integrated these two organically.Based on the mixed spatial data integration mechanism,a platform for water application and publishing of MODIS data has been set up,and applied in high performance,which proved the mechanism for spatial data integration proposed in this paper was flexible and efficient.At last,some advices for further improvement on this approach were given.
