摘要
我国高速铁路控制网中采用高斯投影,它适合于南北走向的铁路,对于东西向铁路就需要划分为多个投影带,这给设计、施工都带来了不便;结合沪杭高铁探讨了斜轴墨卡托投影在高铁路控制网中的应用。
Gauss projection is generally used in control network of our country's high speed railroads.It is used for North-south railroad,while East-west railroad has to be divided into many projection zones,which causes a lot of inconvenience to the design and construction.In this paper,we discussed Oblique Mercator projection through ShanghaiHangzhou high speed railroad.
