We review different techniques to model the Earth's subsurface from geophysical data (gravity field anomaly, magnetic field anomaly) using geological models and measurements of the rocks' properties. We show examples of application using idealised examples reproducing realistic features, while providing theoreitical details of the open-source algorithm we use.

We have developed a software that allows the user to extract and standardize drill hole information from legacy datasets and/or different drilling campaigns. It also provides functionality to upscale the lithological information. These functionalities were possible by developing thesauri to identify and group geological terminologies together.

LoopStructural is an open-source 3D geological modelling library with the model design allowing for multiple different algorithms to be used for comparison for the same geology. Geological structures are modelled using structural geology concepts and techniques allowing for complex structures such as overprinted folds and faults to be modelled. In the paper, we demonstrate automatically generating a 3D model from map2loop processed geological survey data of the Flinders Ranges, South Australia.
