watex.datasets.load_boundiali(*, as_frame=True, index_rhoa=0, tag=None, data_names=None, **kws)

A DC-vertical Electrical resistivity data collected from BOUNDIALI during the National Drinking Water Supply Program (PNAEP) occurs in 2014 in Cote d’Ivoire. An illustration of the data arrangement is the following:

AB/2	MN/2	SE1	SE2	SE…
1	0.4	107	93	75
2	0.4	97	91	49
…	…	…	…	…
100	10	79	96	98
110	10	84	104	104

Parameters:

• as_frame (bool, default=False) –

  If True, the data is a pandas DataFrame including columns with appropriate types (numeric). The target is a panda DataFrame or Series depending on the number of target columns. If as_frame is False, then returning a Boxspace dictionary-like object, with the following attributes:

  • data{ndarray, dataframe} of shape (33, 6)

    The data matrix. If as_frame=True, data will be a pandas DataFrame.

  • resistivity: {array-like} of shape (33,)

    The resistivity of the sounding point.

  • MN: {array-like} of shape (33,)

    The step value of potential electrodes increasing in meters

  • AB: {array-like} of shape (33,)

    The step value of current electrodes increasing in meters

  • feature_names: list

    The names of the dataset columns. .. versionadded:: 0.23

  • DESCR: str

    The full description of the dataset.

  • filename: str

    The path to the location of the data. .. versionadded:: 0.20

  New in version 0.1.2.

• index_rhoa (int, default=0) – index of the resistivy columns to retrieve. Note that this is useful in the cases many sounding values are collected in the same survey area. index_rhoa=0 fetches the first sounding values in the collection of all values.

• tag (None,) – Always None for API consistency

• data_names (None,) – Always None for API consistency

• kws (dict,) – Keywords arguments pass to _is_readable() function for parsing data.

Returns:

data – Dictionary-like object, with the following attributes. - data : {ndarray, dataframe}

The data matrix. If as_frame=True, data will be a pandas DataFrame.

Return type:

Boxspace

Notes

The array configuration is Schlumberger and the max depth investigation is 110.0 meters for \(AB/2\) (current electrodes). The sounding steps \(AB\) starts from 1.0 to 110.0 meters whereas \(MN/2\) (potential electrodes) starts from 0.4 to 10.0 meters. The total number of sounding performers in 4 with the prefix ‘SE’. AB, AB is in meters and SE are in ohm. meters as apparent resistivity values. Use the param index_rho to get the ranking of the sounding resistivity value. For instance index_rhoa=0 fetch the first array of resistivity values (SE1).
