公路控制测量坐标系统的选择

Choice of control survey coordinate system of highway

阐述了公路控制测量的特点,从新投影中央子午线、投影范围、抵偿高程面的确定等方面详细地介绍了公路控制测量坐标系选择的要素,并总结了坐标系统选择的方法,以提高公路控制测量的精度,满足工程施工的要求。

The characteristic of highway control survey were set forth. The principle of choice of control survey ocordinate system of highway was detailly introduced including the determination of central meridian in new projecting, projecting scale determination. The choice method of coordinate system was summarized so as to enhance the accuacy of highway control survey and satisfy engineering construction need.
