Computation, interpretation, and modelling in electrical exploration are essential processes that transform raw field data into meaningful geological insights. Computation involves converting measured voltages and currents into apparent resistivity values using established formulas and electrode geometry. Interpretation then takes these resistivity patterns and relates them to subsurface structures, distinguishing between layers of soil, rock, groundwater, or mineral deposits. This stage often requires integrating geological knowledge and comparing survey results with known models. Modelling, on the other hand, uses mathematical and computer-based techniques to simulate subsurface conditions, refining the interpretation by fitting observed data to theoretical resistivity distributions. Together, these processes ensure that electrical exploration moves beyond simple measurements to provide accurate, reliable, and scientifically grounded representations of the earth’s hidden features, guiding decisions in resource exploration, environmental studies, and engineering projects.
