The integrated exploration is an important way to perform the National Exploration and Development Planning. Based on geological data management and geological data related to mineral prospecting, this paper proposes the geological data integration and service in the equipped exploration area, in which data and maps are collected, the data are integrated, the public data are produced, and the system for publishing data is developed. On such a basis, geologists inquire about the finished data. The research on the geological data integration and service can provide reference for the development of the geological data.
