摘要
通过对地球表面和大地水准面的物理学受力分析发现,传统计算地形改正方法存在误差。分析了其误差来源及大小,解释了该误差形成的原因,并给出了计算地形改正的新算法,新算法可有效提高计算精度。
Through the analysis of the forced Earth＇s surface and quasi-geoid＇ we found out that the traditional method for calculating the terrain correction may make errors.We explained the reasons for the formation of the error,derivated the formula,analyzed the source and size of its errors,and then put forward a new algorithm for calculation of terrain correcting.
