摘要
讨论了 EDM三角高程测量平差模型选择的问题 ,分别用外围大气模型和整体大气模型两类模型对新安江三角高程测量数据进行了试算 ,通过比较分析 ,探索可供实际应用的平差模型 。
In this paper, adjustment model selection for data processing of EDM trigonometric levelling is discussed. Then different models are used for the processing of data from the Xin'anjiang power plant. Through comparison and analysis, the practical model is studied for reduction of refraction error in data processing.
