Geogiga RTomo 6.2 — Resistivity and IP Tomography Software

RTOMO handles resistivity and IP data in a 2-D electrical imaging survey. It supports Wenner, Dipole Dipole, Pole Dipole, Pole Pole, Schlumberger, Wenner-Schlumberger, and other general arrays. Bad datapoints can be interactively removed, or deleted using a median filter, alpha trim, or average filter. The high-resolution topographic correction method and robust tomography approach assure the high processing quality.
