长期以来,重力数据常常是采用各种不同的仪器以不同的方法采集到的,其精度往往参差不齐。由于测点位置分布不均匀,因此重力值便插入到在规则网格上做重力插值处理后可完成横向或垂向梯度计算等处理。有些内插方法还可以计算出内插误差。虽然计算内插所引起的误差是很重要的,但是估算出测量 For a long time, gravimetric data has often been collected in different ways using a variety of different instruments, often with varying degrees of accuracy. Due to the uneven distribution of measuring points, the gravity value is inserted into the grid to do the horizontal or vertical gradient calculation after gravity interpolation on the regular grid. Some interpolation methods can also calculate interpolation errors. Although it is important to calculate the error caused by the interpolation, the measurement is estimated
