摘要
为了评价航磁测量数据的质量,通常采用重复线飞行,计算重复线测量值均方差内符合精度的评价方法,而计算内符合精度,最重要的是准确建立测线和重复线公共线段上的对应测点。笔者研究并采用了最小距离法,计算测线和重复线公共线段上测点对应关系,经过位置改正、磁场水平调整等处理,完成重复线上对应点测量值均方差的计算,获得准确的内符合精度计算结果。
In order to evaluate the quality of the aeromagnetic survey data, it is usually used to measure the repeated lines flying, and calculate internal accord accuracy of them.For this purpose ,the most important is to establish the corresponding measurement points on the measured line and repeated line.We use the minimum distance method to calculate them. and then get the result of the internal ac- cord accuracy.
