A Method for Calculating the Band Change of Gauss Projection Coordinates

Abstract

In geodesy, many surveying projects are carried out on the plane, which requires the transformation of geodetic coordinates, the element on the ellipsoid, into plane coordinates, and each independent coordinate system has new contradictions due to zoning. Based on the basic geometric parameters and the mathematical description of the earth ellipsoid, this paper introduces the principle of Gauss projection method. Since Gauss Krueger projection is currently used in China, this paper introduces the principle and method of Gauss projection, and deduces the correlation between the Gauss plane coordinates (x, y) and the geodetic coordinates (L, (B)), that is, the forward and reverse calculation formulas of Gauss projection. With the help of Gauss projection as a communication "bridge", the coordinate transformation calculation is studied from geodetic coordinate transformation, and its advantages and disadvantages are compared with other methods. Based on the 1954 Beijing coordinate system and 1980 Xi'an coordinate system commonly used in China, a geodetic coordinate conversion system is compiled using C # language, and the forward and inverse calculation of Gaussian projection is realized.
