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.ElectricalMethodscompose the base class of all the geophysical methods that images the underground using the resistivity values. Is another Base class ofelectricalespecially theResistivityProfilingandVerticalSounding. It is composed of the details of geolocalisation of the survey area and the array configuration.Holds on others optionals infos in

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
Trueif 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.
