Two kinds of coordinate projections of Overhauser magnetometer coordinate transformation are studied in this paper. On this basis, the MFC program of Visual C++ is programmed independently. The program implements accurate conversion of Gauss-Krüger projection coordinates and UTM projection coordinates to the WGS-84 geodetic coordinates. It is verified by the examples that both forward projection calculation errors are less than 1.0m. The error of Gauss inverse calculation is less than 10 -3 degrees, while the error of UTM projection coordinate inverse calculation is less than 10 -5 degrees. This research provides assistance for magnetic survey workers to generate coordinate images, and is also the theoretical basis for the corresponding function of magnetometer PC software.
