Gauss projection is a conformal projection, the same coordinate system with the Gaussian projection formula for a conformal projection is based on the principle of derivation of the coordinate system between the two Gaussian function of the significant. The earth in the same coordinate system (such as 1954 or 1980 Beijing Xi' an coordinate system coordinate system), if two Gaussian coordinate system is different from the main meridian of longitude, then the significant function of the coefficient of pre-coordinate system based on the use of elements and the ellipsoid only to determine the main meridian longitude.
