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 basic principle of inclined axis Mercator projection, and gives the corresponding projection back and forth calculation formula. The results of numerical examples show that the relative normal Gaussian projection of incline axis Mercator projection can greatly reduce the projection deformation, so it can be used to establish long linear control network and map projection of high-speed railway construction project.
