I am going to carry out some data acquisitions in urban environments such as roads and paved surfaces. Which geophysics or resistivity/IP/SP imaging company do you suggest for getting the flat-based electrode?
Those flat basis are available in local welder shops you can simply weld your electrode with a flat base it will be cheap and will provide good results for ERS
Also, to conduct ERT survey in an urban environment, you can use the normal electrodes. BUT you have to use a suitable electric drill to make holes for electrodes along the necessary positions in the ERT line. This was conducted in several areas in Malaysia to collect 2D ERT data along the roads. It considered a practical solution for such cases.
Thank you for the comments. I was writing this question because there are errors for the ground electrode due to the driving electrode. Now I want to run a test without hammering. How is possible to get a desirable results?
