Abstract: The national mineral resources potential evaluation project (20062013), a most comprehensive mineral survey since the founding of the Peoples Republic of China, lasted eight years and produced massive (TB) data. How to manage this data depository efficiently and disseminate data widely to researchers has become a critical and difficult issue for data sharing services. Using data generated in the evaluation project and GIS technology, we analyzed key big data technologies such as geological big data storage management, metadatabased query retrieval, spatial data visualization and so on, and proposed a unified information management approach for managing and disseminating the massive, multisourced and heterogeneous geological data. By analyzing and sorting the results data, we built a meta database to store addresses of different types of data, completed the unified data management framework, and realized rapid data query. With the help of the powerful and mature Mapgis K9 function module and open source NASA World Wind 3D Earth engine, we carried out secondary development to set up a data management platform suitable for handling mineral resource potential evaluation results, providing technological support in data dissemination and improving service capability for data sharing.
