“…In recent years, a growing number of Roman towns and military camps have been investigated with mechanically non-destructive methods to large extents [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. Among those, Carnuntum [15,18,21,25,32,33], Falerii Novi [14,30,34], and Portus [16,20,27,28] can be mentioned as three prominent examples. Although many of these Roman towns were researched through a combined terrestrial geophysics-airborne imaging approach, the Bassianae area is unique in its uniformness and emptiness.…”

Integrating Geophysical and Photographic Data to Visualize the Quarried Structures of the Roman Town of Bassianae

et al. 2021

Large parts of the urban layout of the abandoned Roman town of Bassianae (in present-day Serbia) are still discernible on the surface today due to the deliberate and targeted quarrying of the Roman foundations. In 2014, all of the town's intramural (and some extramural) areas were surveyed using aerial photography, ground-penetrating radar, and magnetometry to analyze the site's topography and to map remaining buried structures. The surveys showed a strong agreement between the digital surface model derived from the aerial photographs and the geophysical prospection data. However, many structures could only be detected by one method, underlining the benefits of a complementary archaeological prospection approach using multiple methods. This article presents the results of the extensive surveys and their comprehensive integrative interpretation, discussing Bassianae's ground plan and urban infrastructure. Starting with an overview of this Roman town's research history, we present the details of the triple prospection approach, followed by the processing, integrative analysis, and interpretation of the acquired data sets. Finally, this newly gained information is contrasted with a plan of Roman Bassianae compiled in 1935.

“…• The first [71] uses the GPR (Ground Penetrating Radar) to rebuild an entire buried urban area of the ancient city of Falerii Novi (located about 50 km north of Rome and founded in 241 BC). The choice of this city is due to the fact that, in addition to already having information from the excavations of the nineteenth and twentieth centuries together with an epigraphic and sculptural analysis, it was among the first Roman cities subjected to a complete survey with the gradiometer at vertical flow which has given a very clear plan of the whole site and which has made it possible to frame the urban plan within those typical of contemporary Roman colonies.…”

This paper analyses the application of artificial intelligence techniques to various areas of archaeology and more specifically: (1) the use of software tools as a creative stimulus for the organization of exhibitions; the use of humanoid robots and holographic displays as guides that interact and involve museum visitors; (2) the analysis of methods for the classification of fragments found in archaeological excavations and for the reconstruction of ceramics, with the recomposition of the parts of text missing from historical documents and epigraphs; (3) the cataloging and study of human remains to understand the social and historical context of belonging with the demonstration of the effectiveness of the AI techniques used; (4) the detection of particularly difficult terrestrial archaeological sites with the analysis of the architectures of the Artificial Neural Networks most suitable for solving the problems presented by the site; the design of a study for the exploration of marine archaeological sites, located at depths that cannot be reached by man, through the construction of a freely explorable 3D version.

“…G ROUND-penetrating radar (GPR) is a mature geophysical technique with a diverse set of applications, ranging from glaciology [1] and planetary sciences [2], to archaeology [3] and landmine detection [4]. GPR has been established as a mainstream interpretation tool in hydrogeology [5] and has been successfully applied for permeability estimation [6], mapping the water table [7], delineating clay layers [8], characterizing aquifers [9], deriving the root zone soil moisture [10] and investigating groundwater-dependent ecosystems [11].…”

Full waveform inversion (FWI) is considered one of the most promising interpretation tools for hydro-geological applications using ground-penetrating radar. However, FWI has had limited practical uptake for several reasons: large computational requirements; an inability to reconstruct loss mechanisms of soil; and the need for a good initial starting model. We aim to address these issues via a novel FWI subject to a fractallycorrelated distribution of water. Initially, the dispersive properties of the soil are expressed as a function of the water fraction using a semi-empirical model. This approach means the permittivity, conductivity, and relaxation mechanisms are all correlated, and therefore sensitivity problems between the permittivity and loss mechanisms no longer affect the performance of FWI. Subsequently, the distribution of the water fraction is constrained to follow a fractal geometry. Fractal-correlated noise is then compressed using principal component analysis (PCA) in order to further reduce the number of the system's unknowns and accelerate FWI. PCA reduces the volume and dimensions of the optimization space, and thus, initialisation is no longer necessary. Lastly, a novel measurement configuration is suggested that uses superposition with all the individual measurements in order to reduce the number of forward models that need to be executed for every iteration of FWI. These enhancements substantially reduce the computational requirements of FWI and therefore eliminate the need for high-performance computers and time-consuming algorithms. The proposed scheme has been successfully tested with several numerical case-studies, which indicate the potential of this approach to become a commerciallyappealing interpretation tool for hydro-geology.
