摘要
根据均值漂移模型,针对重力场特点,综合利用高精度DEM数据及绘图法,本文提出了三种重力数据的粗差探测与剔除方法,对重力点数据进行全面的粗差探测与剔除,为建立我国高精度、高分辨率数字大地水准面、垂线偏差模型提供可靠的基本数据;实际结果表明,该方法正确可靠,是一种行之有效的粗差探测与剔除方法。
This study shows three gravity data detection methods to detect outliers according to the mean value drift model.It is based on high accuracy of DEM data and plotting method.What＇s more,it can offer reliable database for the foundation of national high-accuracy and high-resolution data geoid and model of the vertical.According to the results,it is a reliable and feasible detection method.
