| Abstract: | Gauss projection is generally used in control network of China＇s high speed railroads. It is used for North-South railroads,while East-West railroads have to be divided into many projec- tion zones,which causes a lot of inconvenience to the design and construction. We discuss the se- lection of projection method in the case study of Shanghai-Hangzhou high speed railroad. |
