What key factors should be considered during data acquisition in a field survey? Additionally, what are the recommended steps for data cleaning to ensure optimal results, and how can one assess the suitability of the data for inversion both during the survey and after cleaning? Are there any relevant video tutorials available on these topics?

    Hi MdImam, that’s definitely an interesting and broad question! Without diving too deep, I’d say it really comes down to a few key things: clearly defining your survey objectives, choosing the right array, ensuring good electrode-ground contact (to reduce contact resistance), thoughtful electrode spacing and survey design, keeping detailed field records, being aware of cultural noise, and making sure your instrument is properly calibrated and set up.

    Honestly, if you get things right in the field, you’re already a big step ahead — it really reduces the chances of running into noisy data issues when you move into software processing. For solid field practices, most geophysics textbooks have great material. And if you're looking for help with processing, this video could be a good starting point: https://www.youtube.com/watch?v=iW_Dsw_r69c&t=3225s.

    I believe other people in the forum will also be able to share their thoughts and ideas as well on this question. Out of curiosity, are you trying to figure out a specific application or is this a general question?
