The construction and application of ‘3D-one-map’ based on China Geological Survey Information Grid

Abstract：At present, China Geological Survey Information Grid has realized the integration and sharing of geological spatial information through the ‘One-Map of Geology and Mineral Resources’. However, higher requirements of data publishing mechanism and service efficiency should be satisfied for the integration and sharing of the underground 3D space. Based on the framework of the 3D-One-Map of the China Geological Survey Information Grid and starting with the organization and management of 3D spatial data， this paper deals in detail with the discovery mechanism，the integration of 3D visualization and scene services, and the diverse-interface in Geological Survey Information Grid. This service pattern has been implemented and effectively applied to 3D geological models and orebody models, with satisfactory results obtained.
