RES2DINV
• 2D inversion of ERT DC and IP data for resistivity/
conductivity and chargeability
• Supports all common electrode configurations as well as
custom electrode configurations, underwater and cross-
borehole surveys
• Basic data processing options
• Supports smooth and sharp inversions
• Possibility to incorporate known geophysical information
to guide and constrain inversion
• Easy visualization of pseudosections and inversions as
well as export of results to use in visualization and inter-
pretation software
• Time-lapse inversion of datasets, and easy combination
of separate datasets into time-lapse datasets
• Data import from a wide range of native file formats,
including the standard .dat format
