| 摘 要： | 为了检验城市似大地水准面精化项目成果模型的质量,本文利用一定数量的高程异常控制点,以基于EGM2008地球重力场模型及二次曲面函数拟合的方法,构建了一套质量检验模型,其精度优于±5.0 cm。采用质量检验模型比对项目成果模型进行质量分析检验,与外业实地检测相比,检验工作量较小,对项目成果模型的质量评价更全面、可靠。

| Abstract: | In order to test the quality of the city quasi-geoid refining model based on EGM2008 earth gravity field model and the quadric function fitting method,this paper used a certain number of height anomaly control points to build a set of quality test model,whose precision was better than ± 5.0 cm.This paper used the quality test model in analyzing and inspecting the quality compared with the project results model.The results showed that the test workload is smaller,which was compared with the field test and it was more comprehensive and reliable to quality evaluation of the project results model. |
