Correction for topography above and below water is also included. Demo As above, except runs in 16 bit Windows. Sentinel Win driver ver. 5.33 Win3.1, Win95, WinNT4 Free Download and install if you have problems getting the license key to work on your system. MS-DOS Free 2D resistivity forward modeling program that makes it possible to study the response of 2D structures.
Inversion can be one of two cell based algorithms or true polygon inversion.
Demo Res3Dinv will automatically determine a three dimensional resistivity model for the subsurface using the data obtained from a 3D electrical imaging survey in a rectangular grid. The result is presented as horizontal or vertical slices through the resulting volume. This program is absolutely invaluable when it comes to evaluate whether a certain geological situation is going to be possible to resolve using a 3D resistivity survey. To use the program, the user supplies the resistivity value for each cell in a 3D grid using an input text file, the program then calculates the corresponding apparent resistivity and presents the result as horizontal and vertical slices through the grid.
