GeoWiz - eMTEEBlackBox v1.0 : Open Source 1D MT Modelling software

So it's almost been a year since the Geophysics Hackathon run by Agile* Geoscience... I though I might expand on what impact the software our team has made since last October (2014). After making the 1D MT forward modelling software it undoubtedly had many bugs and was poorly constructed, but the idea and a bulk of the code was still pretty good considering the circumstances.

I will release the code after I fix up a few of the remaining bugs. I haven't asked them yet, but I also hope that MTnet can link to the software and help with integrating a few of the algorithms they think will be useful.

New Features

Many of the major bugs and have been fixed and the software expanded

At the conference we had several features:

• Load ASCII MT data
• Interactively forward model a 1D MT response
• Display results

It has since gotten a bit of a polish:

• Data export
• PNG Export
• Data Clearing
• Plotting options
• Unit conversion (m <-> ft) (mS/m<->S/m <-> Ohm.m) (Hz<->S)
• Forward modelling algorithm selection (not just the awesome Java code written by Colton Kohnke) but the Python code written on Digital Earth Lab as well
• Full JavaFX compatibility
• Impedance Plotting
• OSX/Win64 Compatibility

Soon to come:

• A faster 1D MT Algorithm (written in c)
• 1D MT Inversion (Python algorithm complete not integrated)
• Migration to Android and iOS via FXPorts
• Impedance plotting (Yeah, why wasn't this a default option?)

How it has been used?

The best thing about this software is that it has become an invaluable learning tool. It is really easy to use, so easy in fact that the software is now integrated as part the Advanced Electromagnetic and Potential Field Methods in Geophysics 433 unit at Curtin University, soon to be integrated at 3rd year level as well! It is currently being used to teach 20+ undergraduate and masters students the basics of magnetotellurics. Great stuff for software knocked up in 48 hours.

I also use it myself to validate MT data against airborne TEM inversion results and to carry out 1D MT feasibility studies.

Preview

eMTeeBlackBox Modelling to field data (What a dead band!)

Plotting and forward modelling options. Will include more at a later date.

Data selection pane, also notice that you can select between 1D MT algorithms seamlessly.

Final Thoughts

What a difference 48 hours can make.
