上海市水准网复测数据分析与应用

Shanghai Level Net Reiteration Data Analysis and Application

对水准网平差的理论依据、精度评定做了介绍,结合上海市2011年水准网数据,就平差方案、精度评定和成果分析等进行了探讨。通过选取大量的实践数据验证分析,得出了精度较为准确的验证结果,表明采用按照距离定权分等级平差获得的成果可作为此次平差数据处理的最终成果,提出成果的应用方法。

In this paper, the level net adjustment with accuracy assess of the theoretical basis, the paper also introduces combined with Shanghai 2011 level net data, the adjustment with solutions, such as accuracy assess and results are discussed. By choosing a lot of practice validation data analysis, it is concluded that the accuracy of the results of the validation is more accurate, it is shown that according to the distance fixed weight points level adjustment with the results can get as the adjustment with the final results of data processing, put forward the method to use the results.
