GMSys 3D aeromagnetic data issue
I have an aeromagnetci data which was flown at 300 m height. The DEM data ranges from 373 to 2515 m. when I trying to use this data in GMSys 3D, I have to input the survey elevation at constant level above 2515, which is not real. I guess there is something missed, if some one help, will be highly appreciated.
