Hey Guys, In this video I am going to show you how to apply Spectral analysis to an aeromagnetic data. The Spectral Analysis method applied to aeromagnetic grid data allows calculation of an average depth of the causative magnetic bodies. From the slope of the linear segment of the spectrum graph, the depth is calculated. Depth is a function of the decay of the spectrum function within a corresponding frequency interval. In this tutorial your will learn the following: - How to re-project aeromagnetic data - How to window a grid - How to plot map for a grid - How to use the spec file from the spectral analysis in excel to get depth to deeper and shallow magnetic sources.
