摘要
在控制测量中，尤其是建立大面积城市控制网或者较长的铁路控制网都涉及到控制网投影面的选择。根据几个具体实例说明，利用EXCEL表格中的相应功能计算投影变形和投影的高程面，尤其是大型的带状工程，有很大的优越性。
The control survey involves the choice of control network projection planes, especially for the establishment of large-scale urban control network or a much longer train control network. Ac- cording to several concrete examples in this article, the use of EXCEL tables＇corresponding functions has a lot of advantages to calculate the deformation of projection and the projection elevation surface, particularly in large ribbon Engineering.
