摘要
工程测量工作中,为了控制边长投影变形而产生了不同的坐标系。由于边长投影变形的影响,不同坐标系之间不只是数学上的转换关系。通过国家对工程施工测量精度的要求,给出小区域内不同坐标系之间的简易转换方法。
In the measuring of engineering , in order to avoid producing different marks of long flashback transformation. Influenced by the long flashback transformation, the transformation among different marks are not just the number transformation. The accuracy to the engineering construction given by the nation is to give the simply transformation ways of different marks in small areas.
