斜轴墨卡托投影及其在高铁建设工程中的应用

Oblique Mercator projection and its applications on high speed railway construction

本文介绍了斜轴墨卡托投影的基本原理,给出了相应的投影正反算计算公式。通过算例分析表明,斜轴墨卡托投影相对常规的高斯投影能大幅度减小投影变形,因此可以用于建立高铁建设工程等长线性的控制网和地图投影。

This paper introduces the principle of Oblique Mercator projection.The forward and backward equations for Oblique Mercator projection are given.Based on the analysis of results of experimental map projections,we conclude that Oblique Mercator projection can greatly reduce the distance distortion comparing with normal Gaussian projection,and Oblique Mercator projection can be applied to develop a uniform plane coordinate system for high speed railway construction.
