 高速铁路轨道控制测量采用精密控制测量技术,采用斜轴墨卡托投影可以避免高斯投影投影带可控范围小,坐标转换和分带计算的问题,对于东西走向的线路能很好地控制投影长度变形。文章以长吉高铁控制测量数据,实现斜轴墨卡托投影,经过其投影精度的探讨,确定斜轴墨卡托投影能满足高铁精密控制测量的精度要求。 更多还原

【Abstract】 The problems such as the controlled area by projection zone is small,the coordinate transforming and calculating by zones of Gauss Projection can be avoided if control survey of high speed railway tracks adopts precise control survey technology with Inclined Axis Mercator Projection.The projection length deformation can be controlled well of east-west trend lines.This article achieves Inclined Axis Mercator Projection with Changji High-speed Railway control survey data.After the discussion on ac...
