不同椭球参数下高斯投影的差异分析研究

Analysis and Research on the Differences of Gauss Projection with Different Ellipsoid Parameters

在投影计算中,使用不同椭球参数会获得不同的投影计算结果。本文对克拉索夫斯基椭球、GRS75椭球与CGCS2000椭球下高斯投影平面坐标的数值差异、偏移方向和长度变形情况进行了计算及分析,讨论了其在地图制作和GIS数据实践中的应用。

Different ellipsoids parameters lead to different results of projection. In this ethics,we calculated and analyzed the difference of coordinate,the direction of displacement and length deformation with parameters of Krasovsky ellipsoid,GRS75 ellipsoid and CGCS2000 ellipsoid. Finally,we discussed the practice use for cartography and GIS data of the theory that we have put forward.
