Abstract: China Geological Survey grid node system constructed by Development and Research Center of China Geological Survey has initially realized the portal autonomy and collaboration as well as sharing of node resources and portal resources. With the development of information technology, there exists the problem as to how to apply big data and Beidou navigation and communication technology on the grid platform. In this paper, the authors first present the upgrading architecture for the grid platform based on cloud architecture. In addition, the key technologies in such fields as the fast building of geological survey middle-ware, the unstructured geological data storage and management and the field geological work safeguard service used by the grid platform are introduced. The results achieved by the authors provide the theoretical basis for the future development of the grid platform.
