| Abstract: | According to transforming element method of fixed integral,the analytic solutions for authalic latitude function and isometric latitude were advanced in detail by means of the geodetic latitude as an independent variable.The mutual transforming proximate formulas between authalic latitude function and isometric latitude are given.Taking China geodetic coordinate system 2000 for example,the absolute windages of mutual transforming approximative formulae are analyzed.The absolute error of authalic latitude function is between 0.131 3-6.675 8 m2.The absolute deviation of isometric latitude is between-9.171 0e-5-2.254 5e-8 ″. |
