Roadmap and Ideas

This used to be a Project Board; Needs Updating.

A place to keep track of ideas.

Additional modelling routines and utilities

TEM and arbitrary waveform

• empymod#7
• empymod#64

Improve the GPR-routine

• empymod#9

Load and save

Functions to easily store and load model information (resistivity model, acquisition parameters, and modelling parameters) together with the modelling data (~using pickle or shelve~ using h5py; see emg3d).

General

Inversion

• empymod#20
• Inversion routines, preferably a selection of different ones.
  • Add some clever checks, e.g. as in Key (2012): abort loops if the field is strongly attenuated.

Additional (semi-)analytical functions (where possible)

• Complete full-space (electric and magnetic source and receiver); space-time domain
• Extend diffusive half-space solution to magnetic sources and receivers; space-frequency and space-time domains
• Complete half-space

Extend examples (example-notebooks)

• Add different methods (e.g. DC)
• Reproduce published results

Transforms

Filter Library

• empymod#106: See lib-dlf
• empymod#90: Also related

Hankel

• Add the fht-module from FFTLog for the Hankel transform.

Fourier

• Change fft to use discrete sine/cosine transforms instead, as all other Fourier transforms
• If previous step is successful, clean up the internal decisions (utils.check_time) when to use sine/cosine transform (not consistent at the moment, some choice only exists with ffht impulse responses, fqwe and fftlog use sine for impulse, and all three use sine for step-on responses and cosine for step-off responses)

Todo

• Enhancements-Tag in Issues
• Gradients
