This paper firstly introduces the spatial data grid and the CDN (Content Delivery Network) technology. And then it depicts the significance of integrating grid with CDN. On this basis, this paper proposes a method of constructing the spatial data grid system by using CDN to support the massive spatial data online service. Finally, the simulation results by OPNET show that the programme do can improve the system performance, and reduce response time in a greater extent.
