v0.1.9 (March 20, 2023)

This is a change performed from v0.1.8.

• Major feature Add impedance tensor multiple correction class (watex.methods.ZC) and gives opportunity to export new tensor data into EDI files if the argument out=True. For instance:

  • watex.methods.ZC.remove_static_shift() remove the static shift from correction factor from x and y using the spatial median filter

  • watex.methods.ZC.remove_ss_emap() removes the static schift using the EMAP moving average filters such as:

    • 'ama': Adaptative moving average

    • 'tma': Trimming moving-average

    • 'flma': Fixed-length dipole moving average

  • watex.methods.ZC.remove_distortion() removes distortion D form an observed impedance tensor Z.

  • watex.methods.ZC.get_ss_correction_factors() computes the static shift correction factor from a station using a spatial median filter.

• Major feature Add new module ( watex.site.Profile) in watex.site as supplement site data transformation. Gives supplement materials (methods) for data transformation such as:

  • watex.site.Profile.distance() computes the distance between profile coordinates points

  • watex.site.Profile.bearing() computes the bearing between calculate bearing between two coordinates.

  • watex.site.Profile.scale_positions() scale the position coordinates along x and y. This is useful in complex terrain ( high topography )

  • watex.site.Profile.shift_positions() shifts the x and y position coordinates from the step and angle.

  • watex.site.Profile.dms2ll() transforms array x and y from DD:MM:SS to degree decimal -longitude (x) and latitude (y)

  • watex.site.Profile.ll2dms() does the revert process of watex.site.Profile.dms2ll()

  • watex.site.Profile.make_xy_coordinates() generates synthetic coordinates from references latitude and longitude from x and y.

  • watex.site.Profile.interpolate() interpolates x, y and elev ( if applicable).

• Fix Fix bug in updating tensor in _zupdate class of module watex.methods.em. Set the z property attribute using the _z. Idem for z_err which henceforth uses _z_err in watex.externals.z.Z module.

• Enhancement Fix the dependencies when using scikit-learn >=1.2.1. Data was new pickled in version 1.2.1. No more longer uses the 1.1.2 version . Update to >=1.2.1 to avoid the pickle warning at the beginning of package initialization as:

  UserWarning: Trying to unpickle estimator FeatureUnion from version 1.1.2 when using version 1.2.2. This might lead to breaking code or invalid results. Use at your own risk. For more info please refer to:

  warnings.warn(
  

  The following changes are made in the setup.py

  setup_kwargs['install_requires'] = [
  ...
  "numpy >=1.23.0",
  "xgboost >=1.7.3", # rather than  >=1.5.0
  "joblib >=1.1.1", # rather than  >=1.2.0
  "scikit-learn >=1.2.1", # rather than ==1.1.2"
  "threadpoolctl >=2.2.0", # rather than ==3.1.0
  "matplotlib ==3.5.3",
  ]
  

• Fix In watex.utils.gistools.convert_position_float2str() fix the bug related to the use of type(position) is float in the validation of the position value( expected to be a float). type (position) is replaced by isinstance (position, float).

• Fix Bug fix in watex.view.TPlot.plot_rhoa() when errorbar parameter is set to False. No more crash , apparent resistivity plot could henceforth be possible either with errorbar=True or False.

• Feature watex.view.TPlot.plot_corrections() allows to visualize the static shift correction as well as the distortion.
