摘要
首先简单阐明了测区概况和建立该网的基本情况。介绍了在建网过程中选点和埋设点所采用新方法,同时论述和分析了该网数据处理情况和平差后各项指标精度情况。分析了采用等值线图确定GPS正常高的方法精度情况,并与常规方法作比较得出正确结论。
The paper introduces basics of surveying area and network establishment, the new methods for point selection and bury. Meanwhile, the paper analyses the indicator accuracy after the adjustment, and comes to the conclusion by comparing the GPS normal height accuracy by using contour method and regular method.
