高斯投影是正形投影的一种，同一坐标系中的高斯投影换带计算公式是根据正形投影原理推导出的两个高斯坐标系间的显函数式。在同一大地坐标系中(例如1954北京坐标系或1980西安坐标系)，如果两个高斯坐标系只是主子午线的经度不同，那么显函数式前的系数可以根据坐标系使用的椭球元素和主子午线经度唯一确定。-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.
