libaarhusxyz

Parser for the XYZ family of formats for electromagnetic geophysical measuerement data and resistivity models.

Supported data formats

• Aarhus Workbench XYZ model format as documented in the Workbench reference
• Aarhus Workbench XYZ data format
• SkyTEM XYZ format

Supplementary data formats

• Geometry files (.gex), defining the SkyTEM system and the used waveform
• System response files (.sr2)
• Workbench column mappings (.alc)

Export formats

• geojson of flightlines
• vtk 3d views of resistivity models

Binary exchange format

This library can also convert to and from a msgpack based container format. This format can e.g. be read in a web browser, and also removes the issue with numerical precision inherent in text format to/from float conversion. There's a javascript companion library for working with this format in the browser.

Examples

For usage details, see Example usage notebook.

Other tools

We have developed interface code for the SimPEG inversion software to work directly with measured data from SkyTEM systems (Tested with 304 and 306) in XYZ format using libaarhusxyz. Example notebooks can be found here.
