simpeg.electromagnetics.static.utils.convert_survey_3d_to_2d_lines#
- simpeg.electromagnetics.static.utils.convert_survey_3d_to_2d_lines(survey, lineID, data_type='volt', output_indexing=False)[source]#
Convert a 3D survey into a list of local 2D surveys.
Here, the user provides a Survey whose geometry is defined for use in a 3D simulation and a 1D numpy.array which defines the line ID for each datum. The function returns a list of local 2D survey objects. The change of coordinates for electrodes is [x, y, z] to [s, z], where s is the distance along the profile line. For each line, s = 0 defines the A-electrode location for the first source in the source list.
- Parameters:
- survey
simpeg.electromagnetics.static.resistivity.Survey A DC (or IP) survey
- lineID(
n_data)numpy.ndarray Defines the corresponding line ID for each datum
- data_type{‘volt’, ‘apparent_resistivity’, ‘apparent_conductivity’, ‘apparent_chargeability’}
Data type for the survey.
- output_indexingbool, default=False,
optional If
Trueoutput a list of indexing arrays that map from the original 3D data to each 2D survey line.
- survey
- Returns:
- survey_list
listofsimpeg.electromagnetics.static.resistivity.Survey A list of 2D survey objects
- out_indices_list
listofnumpy.ndarray,optional A list of indexing arrays that map from the original 3D data to each 2D survey line. Will be returned only if
output_indexingis set to True.
