The nucleation of the rural population was a widespread phenomenon during the Middle Ages that interested many areas of Western Europe. However, many of these sites are now deserted with the underlying phenomena causing these abandonments not always easy to reconstruct. Archaeologists have been interested in these medieval settlements since the middle of the 19th century, and remote sensing has played a decisive role in mapping hundreds of them. This also applies to many parts of the Po Valley but not the Romagna plain, where hundreds of medieval sites are known but almost exclusively based on written sources. However, the increasing availability of aerial and satellite images offers a valuable opportunity to bridge this knowledge gap. The systematic study of legacy images allowed the mapping of new defensive elements and reconstruction of the general plan of six deserted medieval fortified settlements in the broader hinterland of Ravenna. PlanetScope 3m resolution images were later exploited to continuously monitor these sites during periods prone to crop marks formation to detect the presence of wide crop/soil marks (e.g. ditches). Six successful field verifications demonstrate that these 'coarse' images are sufficient to plan drone surveys that can allow the mapping of additional smaller features. [ABSTRACT FROM AUTHOR]

This paper focuses on a multidisciplinary approach used mainly in the post-processing of the data collected in the intensive survey carried out in 2018 in San Basilio di Ariano nel Polesine (RO). At first, the interpretation of aerial photos and the DTM processing for the area of San Basilio have been used to identify features of the ancient landscape before the field survey, in order to better plan the investigations; the results of the analysis on remote sensing and DTM data have been also used during the post-processing phase. Then, the data collected in the field have been digitalized, organized and processed in a database and a GIS, using both cluster analysis and data classification. The research has allowed us not only to confirm and expand the context of the historical and environmental evolution of the area during pre-Roman and Roman period, but also to reflect on the methodology used for the data collection and processing within an intensive field survey. In particular, cluster analysis and numerical classification methods have been compared in order to better understand their potentialities and limits in the data analysis. [ABSTRACT FROM AUTHOR]

This paper deals with the practical application of photogrammetry in the study of the Roman city of Doclea in Montenegro, with particular reference to the use of Structure from Motion (SfM) techniques. Among the various research areas, archaeology of architecture and settlement archaeology make today an increasing use of photogrammetry for the in-field documentation of archaeological features. This method has an essential role in obtaining a reliable geometric survey that in turn forms the basis for the structural assessment of the architectural heritage thanks to consolidated methods such as archaeological stratigraphy and direct examination. In recent years, digital photogrammetry and the implementation of data processing technologies have made it possible to create three-dimensional models using images acquired through high-definition cameras. In addition to an accurate topographical survey, the aforementioned methods offer the opportunity to obtain a faithful representation of the real world, providing a basis for subsequent architectural and territorial studies. The use of drones equipped with cameras has proved to be particularly effective and capable of detecting large areas quickly and with good results. Due to its versatility and relative ease of use, photogrammetry could actually be deemed as an essential tool for the study and conservation of cultural heritage. [ABSTRACT FROM AUTHOR]

The paper presents a reconstruction of the ancient morphology of the early medieval port of Comacchio through Kriging and Radial Basis Functions algorithms, and 3D models of the archaeological remains. The predicted surfaces are in significant accord with past hypotheses, also providing a good amount of certainty from a scientific point of view, since they appear extremely consistent with the geological data collected through stratigraphic corings. As a whole, the predicted surfaces and the 3D reconstructions of the wooden remains of the port offer fresh perspectives on the interpretation of the site by showing the existence of different building phases and spatial organizations, thus providing new guidelines for future excavations.

Over the past few decades Geographical Information Systems in archaeological practice and above all in urban archaeology have become a standard tool for understanding the development of late antique towns. This paper analyses the city of Ravenna as a case-study, illustrating some standard and innovative GIS applications in a city characterised by non-systematic archaeological research. GIS helped us to systematize archaeological investigations and to guide city planning. New important excavations, in Piazza Kennedy, with the discovery of the 5th c. church of S. Agnese, and other smaller trenches in the city centre, add a fundamental collection of archaeological data. The creation of new chronological evaluation maps highlighted empty research zones in the old city, where urban archaeology should focus new excavations and archaeological evaluation projects.

This paper focuses on a survey of the Predictive Archaeology domain, including a review of its key developments since the 1960s. A working and minimalist definition of “Predictive Archaeology" (P) – which becomes “Preventive Archaeology" in its application, that is, when it is expressed through the quantification of the risk of archaeological impact – may be that of a prediction technique for locating archaeological sites in terra incognita, based on a sample of known sites (terra cognita) or on assumptions about human location/allocation behavior in the past. A prospective view of possible short-term evolutionary scenarios is also illustrated. [ABSTRACT FROM AUTHOR]
