Base class of geophysical electrical methods

The electrical geophysical methods are used to determine the electrical resistivity of the earth’s subsurface. Thus, electrical methods are employed for those applications in which a knowledge of resistivity or the resistivity distribution will solve or shed light on the problem at hand. The resolution, depth, and areal extent of investigation are functions of the particular electrical method employed. Once resistivity data have been acquired, the resistivity distribution of the subsurface can be interpreted in terms of soil characteristics and/or rock type and geological structure. Resistivity data are usually integrated with other geophysical results and with surface and subsurface geological data to arrive at an interpretation. Get more infos by consulting this link .

The watex.methods.electrical.ElectricalMethods compose the base class of all the geophysical methods that images the underground using the resistivity values. Is another Base class of electrical especially the ResistivityProfiling and VerticalSounding. It is composed of the details of geolocalisation of the survey area and the array configuration.

Holds on others optionals infos in kws arguments:

Attributes

Type

Description

AB

float, array

Distance of the current electrodes in meters. A and B are used as the first and second current electrodes by convention. Note that AB is considered as an array of depth measurement when using the vertical electrical sounding Vertical Electrical Sounding method i.e. AB/2 half-space. Default is ``200``meters.

MN

float, array

Distance of the current electrodes in meters. M and N are used as the first and second potential electrodes by convention. Note that MN is considered as an array of potential electrode spacing when using the collecting data using the vertical electrical sounding Vertical Electrical Sounding method i.e MN/2 halfspace. Default is ``20.``meters.

arrangement

str

Type of dipoles AB and MN arrangememts. Can be schlumberger Wenner- alpha / wenner beta, Gradient rectangular or dipole- dipole. Default is schlumberger.

area

str

The name of the survey location or the exploration area.

fromlog10

bool

Set to True if the given resistivities values are collected on base 10 logarithm.

utm_zone

str

string (##N or ##S). utm zone in the form of number and North or South hemisphere, 10S or 03N.

datum

str

well known datum ex. WGS84, NAD27, etc.

projection

str

projected point in lat and lon in Datum latlon, as decimal degrees or ‘UTM’.

epsg

int

epsg number defining projection (see http://spatialreference.org/ref/ for moreinfo). Overrides utm_zone if both are provided.

Notes

The ElectricalMethods consider the given resistivity values as a normal values and not on base 10 logarithm. So if log10 values are given, set the argument fromlog10 value to True.
