VOXI magnetics: TMI or RTP and database vs. grid
I'm a bit new to aeromagnetic data and to VOXI inversions. My first question is if reduction to pole should be done on the data input to VOXI? I tested 1) using the TMI without the reduction to pole and then specifying the IGRF for the survey date in the VOXI data import dialog, and then 2) using data that were already…

Negative apparent magnetic susceptibility values
Hi, I have been trying to derive near surface apparent magnetic susceptibility from aeromagnetic survey data. In order to do this I have been applying high pass butterworth filters (experimenting with different wavelengths) to try and isolate the residual field and then performing an apparent susceptibility calculation…

Which is the correct workflow for airborne magnetic data
I need to process airborne magnetic data and make all the actions required (qa/qc, corrections, leveling, filtering, etc).
