Overview of Modelling Concepts

Forward modelling involves creating a hypothetical geologic model and calculating the geophysical response to that earth model. GM‑SYS is a modelling program that enables intuitive, interactive manipulation of the geologic model and real-time calculation of the gravity and magnetic response.
