Parser for the XYZ family of formats for electromagnetic geophysical measuerement data and resistivity models.
- Aarhus Workbench XYZ model format as documented in the Workbench reference
- Aarhus Workbench XYZ data format
- SkyTEM XYZ format
- Geometry files (.gex), defining the SkyTEM system and the used waveform
- System response files (.sr2)
- Workbench column mappings (.alc)
- geojson of flightlines
- vtk 3d views of resistivity models
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.
For usage details, see Example usage notebook.
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.
