%X This paper proposes a new model for grid task distribution. This model combines Grid computing idea for role task decomposition with 3D GIS navigation technique. In this model, by decomposing the complicated computa- tional task of 3D GIS into little blocks and assign them to many task node to complete cooperatively and synchronously according to the roles that these nodes take on, many computers can process according to their own roles the task realtimely and orderly which was originally disorderly done by only one computer. This model can solve not only the problems of disordered distribution of network resources and lack of management of communication between various nodes that exist in.the traditional grid computation, but also such questions as poor 3D vagile speed, high request for server equipment and navigation intermission, which exist in traditional 3D GIS navigation and come of large amount of 3D data and complicated operation.
