Abstract The high precision magnetic survey is liable to suffering many kinds of surface interference which cause data distortion; therefore, the distortion points must be rejected before processing. For the purpose of implementing interactive rejection of distortion points in magnetic data, the authors employed the functions of Matlab GUI, which are characterized by visualization, drawing and mouse case. In practical application, this method enhances the efficiency of rejecting distortion points in magnetic data and preserves most information of normal data points.
