| Abstract: | Based on the deformation of Gauss-Kruger projection and the requirement of projection deformation ,this paper presents three different ellipsoid-transform metods to establish the independent coordinate system ,specific formula and parameter selection principles .A new software is designed to avoid the shortages of current program and the calculation has been simplified .The details to solve these parameters and control point coordinates value date are analyzed with examples ,and some meaningful conclusions based on different methods are drawn to show the strengths and weaknesses as well as the scope of local independent coordinate system . |
