That is a screenshot from RES2DINV by Geotomo (now owned by Aarhus Geosoftware, who is owned by Bentley Systems). It is the most common electrical resistivity tomography (ERT) software worldwide.
Performing ERT surveys with only a single channel resistivity meter (2 current electrodes and 2 voltage electrodes) is one of the most tedious tasks in geophysics. I did a 100 m long survey over a tunnel leading out of the world's largest prison with a system like that. It took me four days to do a survey that I could do with a multichannel switching system in a few hours. One should only perform a survey like this if they have a lot more time than money, or if they are on the other side of the planet and their switching resistivity system is at home.
