| Abstract: | This article took a railway of northeast as an example to discuss the role of the establishment of an independent coordinate system of railway,and introduced several ways to establish these systems.Then in this paper,project elliposoid constructing model was used in the establishment of project independent coordinate system.Meanwhile,the coordinate conversion model from the State Coordinate System to project independent coordinate system was described in detail,and the related program for computing the project independent coordinate system was designed in the end. |
