摘要
通过城市大型一级导线网测量及其观测数据处理的实践,在平差前,根据导线网观测条件,以估算测角、测边先验中误差为基础,合理选择平差时边角先验权的匹配方案,以取得理想的平差结果。根据边角观测精度的综合因素,适当地选择几组边角先验权匹配方案进行试算,最后确定较为理想的一组边角先验权匹配方案,再进行正式平差计算和精度评定。
Through the practice of surveying and data procession in urban 1st grade traverse network,we reach a conclusion:Before adjustion,according to the observation conditions,based on the RMSE of angle and line,we can choose the correct way to reach the reliable adjusted result.According to the comprehensive factors of the angle and line observation,we choosed several group of line and angle for test,finally choosed one group as the best group.In the end,we can formally calculate the adjustion and the presion evaluation.
