EVALUATION OF INTERPOLATION RESIDUAL ACCURACY WITH MIDPOINT OF CHECK LINES IN MARINE MAGNETIC SURVEY
磁异常插值残差精度检查线中点评估法

In order to improve the accuracy of magnetic diagram from marine magnitic surveying the evaluation method of the interpolation residual accuracy with midpoint of the cross-check lines was brought forward,and the relation between the interpolation residual accuracy and line spacing was analyzed.The study shows that the method can make full use of information along the check lines,the interpolation ability between the lines can be really reflected but the interpolation residual accuracy will reduce with the increase of the line spacing.
