Recently, jointly by the Development Research Center of the China Geological Survey, 7 The “3D Geological Model Data Exchange Format,” drafted by research institutions and organizations engaged in industry, education, research, and application. Geo3DML )》standard, approved and issued by the China Geological Survey, providing technical support for the exchange and sharing of 3D geological survey data in China.

3D Geological Model Data Exchange Format ( Geo3DML )》 (No. DD2015-06 ), which specifies the organizational hierarchical structure for 3D geological model data exchange, as well as the exchange formats for spatial geometric data, attribute description data, and 3D visualization data of geological models. It supports the exchange of various types of data—such as 3D point, line, surface, solid, voxel, and annotation objects—that are applicable to different geological fields (including regional geology, hydrogeology, engineering geology, environmental geology, mineral geology, and energy geology, among others)—as well as data related to boreholes, geological maps, cross-sections, and contour maps.

In addition, to support Geo3DML For promotion, we have developed a visual support tool. Geo3DML Viewer Standard interface development kit Geo3DML SDK and has established a special website for promoting the standards. www.geo3dml.cn。

Note: Due to the wide variety of 3D geological modeling software currently in use, each software employs different data models, making it difficult to achieve integrated management and seamless exchange and sharing of 3D geological model data. Moreover, both domestically and internationally, there is still a lack of standardized protocols for the exchange and sharing of 3D geological models. To address this issue, the China Geological Survey... “ The 12th Five-Year Plan ” During this period, multidimensional geological modeling and analysis technologies were established, and the project “Technical Requirements for 3D Data Exchange” was formulated. Research was conducted on technical methods for the exchange and sharing of 3D geological model data, and the proposed research findings... Geo3DML The standard provides a technical foundation for the exchange and sharing of 3D geological model data.
