摘要
在多级导线网统一平差更加严密、合理的设想下 ,根据德州市德城区已形成的首级控制网和加密的一级导线网数据 ,通过重新进行统一平差 ,对多级导线网统一平差需解决的有关问题进行了研究。文章对多级网中多类、不同等级观测值的权匹配问题和粗差探测问题进行了分析讨论 ,并用科傻测量控制网数据处理软件(CosaWIN)计算出了相应的结果 ,最后结合计算结果 。
This paper is based on the idea that multi-order traverses united adjustment is more vigorous and reasonable. The data resources are from the tertiary traverses and the 5″ densifieds traverse networks of Decheng District of Dezhou City. The related area of multi-order traverses united adjustment is studied together with the above network. The weight assigmment of different observations and gross error detection are also analyzed. Finally, the adjusted result got by the Surveying Control Network Data Processing Software(CosaWIN) is given. The conclusion is then listed at the end.
