| Abstract: | This paper describes a new method of the establishment of a regional independent system by transforming regional ellipsoidal surface.Taking a mountain road for example,it is expounded that ellipsoid expanding model,ellipsoid shift model and ellipsoid distortion model is used in establishing regional coordinate system,then the author analyses projection distortion that three methods establish coordinate system,comparing of the characteristics of three methods. |

| Keywords: | ellipsoid transform regional coordinate system projection distortion |
