Aeromagnetic survey generally require much more pre-processing steps than that of common land survey dueto several complex and cumbersome steps included in pre-processing stage. Therefore it is desirable to use specificprocessing tool especially based on graphic user interface. For this purpose, aeromagnetic pre-processing software basedon graphic user interface under the Windows environment, called KMagLevellingTM was developed and briefly introduced. In an aspect of its user-friendliness and originality, three noticeable features of KMagLevellingTM are summarized as thefollowing ① function of representation and handling for large amount of aeromagnetic data set as a visualization in theform of flight-path ② function of selective exclusion of unwanted data by using survey area information expressed aspolygon, and ③ function of selective removal processing for the irregular flight-path data acquired within the entire surveyarea by implementing the segmentation of flight-path technique.
