Three-dimensional geophysical data integration at Portus, Italy
Geophysical surveys that utilise more than one technique are becoming commonplace in geophysical fieldwork strategies in order to acquire more information about the subsurface. Integration techniques, however, are seldom utilised in particular with three-dimensional geophysics data. There are a number of geophysical techniques that collect three-dimensional data for instance ground penetrating radar (GPR), electrical resistance tomography (ERT) and electromagnetic induction (EMI). Three-dimensional data enables the estimation of the volume of archaeological features and allows for stratigraphic relationships to be identified. Integration provides methods of analysing the composite information from the individual datasets simultaneously, thus providing enhanced understanding of the subsurface. Furthermore, utilising these methods with three-dimensional data will provide a significant advancement in the understanding of the subsurface that is currently possible with data from individual geophysical techniques alone. While demonstrable advances in the visualisation of archaeological features using integration have been presented in the last 10 years (Piro, et al. 2011), this has mainly focused on two-dimensional
