To address the issues of low efficiency and high error rates associated with traditional manual methods for converting coordinate formats in the mineral resources national survey database, two conversion approaches and program algorithms are proposed: First, a forward conversion that transforms coordinate strings of mining areas (mines) in the database into coordinate pair text files; Second, a reverse conversion that transforms coordinate pair text files back into coordinate strings of mining areas (mines) in the database. These methods can provide data that meet format requirements for coordinate system conversion of mining areas (mines) in the database, and enable rapid rewriting of coordinate values and database updates after coordinate system conversion, thereby effectively enhancing the automation level of coordinate data processing and data management efficiency.
