The Gauss projection has three conditions, from which we can derive the
formula for a direct solution of the Gauss projection.
A Gauss projection is carried out along the narrow strips within a certain
longitude east and west of the central meridian. In each projection area, the
difference l between the longitude of an arbitrary point and that of the central
