| Abstract: | This paper discussed the method of establishing local independent coordinate system through Ellipsoid transformation. Taking a road in mountain area as an example,it established local independent coordinate system using Ellipsoid Expanding Model,Ellipsoid Shift Model, and Ellipsoid Distortion Model. Then it analyzed the projection distortion value of the independent coordinate system by these different models. It also compared the characteristics of the three models. |
