Abstract: The scientific data is an important national strategic resource, and data sharing is one of the means of effective exploitation and utilization on this resource. It is also an important basis for the transformation of current scientific research paradigm to data intensive. With the deep integration of modern information technology and exploration methods, geological exploration and geoscience research are being pushed into the era of Big Data, and it is urgent to conduct scientific management from the macro level. The developed countries in Europe and the United States have promoted the effective implementation of their own geological big data management by issuing policies and laying data infrastructure. In this paper, it investigates the data management work of the Geological Survey in the United States, Britain, Australia and Canada, and introduces and analyzes the status quo of the data management scope which including data policies, strategic plans, important databases and main data tools. Some Suggestions on data management in geological survey industry in China are put forward as follows: (1) Data management policy should adopt top-down design and implement bottom-up. (2) Open sharing and integrated communication of data is the development trend of global data research institutions in the future. (3) We will vigorously promote the construction of GeoCloud, and implement big data governance in the trinity of big data, artificial intelligence and cloud computing. (4) The construction of data sharing infrastructure should be promoted, and more discourse power should be gained through participating in inter- national governance.

Key words: geological big data, geological survey organization, data sharing, policy, data management
