Summary

tl;dr This webinar covers some features to process resistivity (RES) and induced polarization (IP) 1D, 2D, 3D, and 4D RES/IP data sets with and without topography. Emphasis is made on QA/QC for collected and processed data sets from various settings throughout the webinar. Our EarthImager software 1D, 2D, and 3D packages are used to process the RES and IP data sets.
