In this paper through Honam high-speed railroad which is planned with the north and south axis, we will verify the feasibility of the coordinate conversion using railroad control points after regarding current planned-railroad as the linear central axises. From analysis, distortion of Y axis varies 21㎝ to 40㎝ diminishing to a gentle straight line, distortion of X axis varies 14㎝ to 29㎝. Through a revision, the deviation value between the coordinates were 6㎜ to 9㎜ and it satisfied the allowable error of national geographic information institute which is following ITRF (International Terrestrial Reference Frame) and cadastral boundary survey(10㎝). consequently the coordinate conversion is possible using railroad control points as co㎜on control points.
