From a practical perspective, using the Excel VBA computing platform, taking real isometric latitude as the transformation parameter, and adopting the geodetic coordinate increment method and spatial Cartesian coordinate method as the expansion transformation method, different surface Gaussian projection transformation macros were developed to achieve batch transformation of coordinates with one click. The offset (Dx,Dy)of ellipsoidal expansion coordinates is mainly contributed by the increment daof the ellipsoidal semi axis, and it increases linearly with da.展开更多
