Paper Abstract

With the development of high-speed railway in recent years, the previous precision of control surveying and the methods of data processing will not meet the requirement of high-speed railway any longer. In view of the characteristics of precision is much higher in large-scale precise construction and the superiority of precision in reform of large-scale engineering control networks, in this paper, using the algorithm of ellipsoid expansion to deal with overrun coordinate projection distortion in high-speed railway, then compares with common calculation method of surveying, we get a conclusion that this method can get minimum projection and it accord with the requirement of high-precision control surveying.
