Overview
A resistivity-IP object represents geolocated, time-stamped resistivity and induced polarization (IP) survey data. This data is used extensively in exploration for mineral resources, environmental investigations, and other fields where the electrical properties of subsurface materials provide insight.
The number_of_dimensions parameter describes the survey dimension and can take one of the values "1D", "2D", or "3D".
The number_contributing_electrodes parameter indicates the number of contributing electrodes, excluding remote electrodes.
The survey object includes details about the survey type, which can be one of the following:
- DCIP (Direct Current Induced Polarization): Measures the voltage decay after current injection is switched off, characterising subsurface chargeability. Includes timing information, duty cycle, and number of pulses per recording
- SIP (Spectral Induced Polarization): Specifies a list of frequencies used during measurement
- PHASEIP (Phased Induced Polarization): Specifies a list of frequencies used during measurement
- DCRES (Direct Current Resistivity)
The configuration object includes details about the survey configuration, as well as location information for the remote survey elements in the case of Pole-Dipole (one current electrode at "infinity", offering good lateral resolution) or Pole-Pole (both a current and potential electrode at "infinity", offering the deepest penetration but lowest resolution).
The line_list array includes one or more resistivity-IP line definitions, including the group_number, date, station, number_of_electrodes, and channel_attributes.
