Integrated use of aerial and ground-based close-range remote sensing techniques to support preventive archaeology: the case study of Ascoli Satriano (FG)

The present work aims to show the multi-sensor close-range remote sensing (RS) activities carried out in the municipality of Ascoli Satriano (FG Apulia). The site is of great significance as it has been continuously occupied from the 8th century B.C. to the present day. The site is famous for the discovery of marble griffins dated to the 4th century B.C., probably inside a princely tomb. The study was conducted using a multispectral UAS and a ground magnetometer. The results of the RS analysis showed a complex scenario, with features of buried remains related to roads, paleo-channel, and, above all, circular structures of considerable size. The latter, as confirmed by the targeted excavations conducted following the RS acquisitions, are referable to monumental tumuli. The integration of several sensors has made it possible to overcome the limits of single instrument observation and to provide useful data for practical preventive archaeological work.

The study of Limes Arabicus using aerial and satellite remote sensing documentation. The case of Umm ar-Rasas (Amman, Jordan)

Limes Arabicus is an excellent laboratory for experimenting with the enormous potential of historical and modern remote sensing data for the identification and recording of fortified centres located along this sector of the Roman Empire s eastern frontier, which then also became the Byzantine Empire s eastern borderline. Remote sensing, in conjunction with modern survey techniques and tools such as photogrammetry and laser scanner surveys, enables the identification, documentation, and study of ancient settlements in this area, as well as the development of site valorisation programmes such as the design of real and virtual routes for better use of archaeological areas. In this paper, a preliminary contribution focused on aerial and satellite remote sensing documentation concerning the site of Umm ar-Rasas (Amman, Jordan), a fortified settlement along the Via Traiana Nova, is presented.

Significant data and information in complex analysis of the architectural heritage, the Republican Museum of Itu, Brazil

Innovative digital tools make it possible to investigate and understand elements of architectural heritage based on considerations extracted from historical and physical analyses, and to use a large quantity of information acquired with technologically advanced tools (e.g, photogrammetry and image-based modeling systems ). These tools allow us to investigate the form, reconstruct the process of designing, and study formal, proportional, and spatial features of archeological elements. The interrelation between theory, methods and application opens the possibility to achieve complete results as far as archaeological documentation, analysis and interpretation. On one hand, these high precision digital tools realistically show surface qualities; on the other hand, in the process of production of these models, it s possible to extend the knowledge of archaeological artefacts through the investigation of the material and its articulation with other components of the building, it offers a complex process of interpretation of historical aesthetical aspects, materials and surfaces.

Electromagnetic survey to detect a section of the Messapian city walls in Ugento (Lecce)

The Messapian city walls in Ugento (Puglia, in south Italy) are of great archaeological importance and some sections are still visible. In order to locate a stretch of the city walls, a non-destructive geophysical prospection was performed, applying the electromagnetic method. The survey was carried out in a peripheral area of Ugento, near a visible section of the city walls. The analysis and interpretation of the measured electromagnetic data (specifically in this work, the quadrature-phase component) revealed a clear anomaly that could be ascribed to the city walls; in fact, it is aligned with the adjacent section of the visible walls.

Integrated survey techniques for historical architectures: first results for Santa Maria della Croce in Casaranello, South of Italy

Historic buildings are complex structures because of both materials and construction techniques that have occurred between the different eras, as well as from the historical point of view (periods of abandonment, changes of use, changes on the original plant, etc...). All events leave marks on the building that form layers legible with different techniques and appropriate analytical procedures. In recent decades, stratigraphic analysis of both positive and negative units has been performed through non-invasive and non-destructive techniques.
Here the authors propose a combined analysis of different techniques in order to obtain a complete knowledge of the architectural structure of the building under investigation. The case study chosen is the church called S. Maria della Croce whose architectural vicissitudes are and have been the subject of study for the relevant historical interest of the monument. The investigation techniques identified to analyze the stratigraphic units of the building are 3D scanning, infrared thermography, and ground penetrating radar (GPR) techniques. These investigations aim to understand what was the original function of the building.
In this paper preliminary information of the research activity is reported, related to the thermographic investigation carried out on the front facade of the church object of investigation, through which the authors want to highlight possible traces of occlusions, openings, removal of materials that can clarify the original use of the monument.
