Global GIS is a system, which supports the huge data process and the global direct manipulation on global grid based on spheroid or ellipsoid surface. A new Global GIS architecture based on STQIE model is designed in this paper, according to the computer cluster theory, the space-time integration technology and the virtual real technology. There is four-level protocol framework and three-layer data management pattern of Global GIS based on organization, management and publication of spatial information in this architecture. In this paper a global 3D prototype system is developed taking advantage of C++ language according to the above thought. This system integrated the simulation system with GIS, and supported display of multi-resolution DEM, image and multi-dimensional static or dynamic 3D objects.
