ELETOM - Electrical Tomography
ELETOM is a software that performs complete 2D inversion (and not the simple iterative deconvolution of the pseudo-sections) of surface electrical surveys with any measurement array (Wenner, dipole-dipole, pole-dipole, pole-pole, user defined arrays, mixed arrays) with a maximum of 64 electrode positions that can be added by the user as required.
ELETOM uses the finite elements method (FEM) in two dimensions to model the electrical response of the subsurface.
The elements that define the grid are trapezoidal in form to enable one to compensate any height differences between the electrode positions. The current dispersion in the third spatial dimension (perpendicular to the section of interest) is taken into consideration using Wannamaker's correction.
