摘要
通过三维控制网的实际布设,对GPS平面控制网的精度和数字水准仪布设的高程控制网的精度进行了分析探讨,并对二者如何更加有效的结合提出了几点有益的见解。
Through the actual building of the three-dimensional control network, this article has carried on the analysis and the discussion to the precision of GPS horizontal control network and the elevation control network built by the digital level, and proposed several beneficial opinions to make the two more effective combination.
