watex.utils.type_#

watex.utils.type_(erp)[source]#

Compute the type of anomaly.

The type parameter is defined by the African Hydraulic Study Committee report (CIEH, 2001). Later it was implemented by authors such as (Adam et al., 2020; Michel et al., 2013; Nikiema, 2012). Type comes to help the differenciation of two or several anomalies with the same shape. For instance, two anomalies with the same shape W will differ from the order of priority of their types. The type depends on the lateral resistivity distribution of underground (resulting from the pace of the apparent resistivity curve) along with the whole Electrical Resistivity Profiling survey line. Indeed, four types of anomalies were emphasized:

“EC”, “CB2P”, “NC” and “CP”.

For more details refers to references.

Parameters:

erp – array-like - Array of Electrical Resistivity Profiling line composed of apparent resistivity values.

Returns:

str -The type of anomaly.

Example:
>>> import numpy as np
>>> from watex.utils.exmath import type_
>>> rang = np.random.RandomState(42)
>>> test_array2 = rang.randn (7)
>>> type_(np.abs(test_array2))
... 'EC'
>>> long_array = np.abs (rang.randn(71))
>>> type(long_array)
... 'PC'
