摘要
本文应用三维平差、粗差检验等方法，对２００多个露天采场的测角后方交会点进行统计分析，得出测角中误差、点位中误差、高程中误差等实际精度指标．
y using three-dimensional mean difference,gross error test method ect.,the statisticalanalysis of resected point of more than 200 open-pits are conducted in this paper,and the practical precision indexes of the mean square errors of surving angle,point and altitude are obtained.
