Gridding Geophysical Aeromagnetic Data from XYZ data in order to obtain a Grid with Magnetic Field, Elevation and other columns using Python or Simpeg

Hello

I have Geophysical aeromagnetic data that was collected in 2014 via the Helicopter. The raw data consist of XYZ whereby the X and Y is the location and the Z is the depth. I use Ubuntu Linux and I wanted to use the SIMPEG in order to grid the data but this tool gives me options for analyzing the already gridded data.

I was wondering if you can assist me with any Python library or how can I use SIMPEG in order to grid my data to obtain the Magnetic field in nanotesla, Elevation(m) from the raw XYZ data

Hi mandalfred!

I know that SimPEG has implemented equivalent sources, which would allow you to interpolate scattered magnetic data.

But I can also recommend Harmonica. In there you will find the EquivalentSources class that will allow you to interpolate harmonic data (like gravity and magnetics fields) using equivalent sources.

Hope it’s useful for you!
