This paper deals with the integration and fusion of UAV-based imagery, including Vis-NIR multispectral and infrared thermography data, with georadar and geomagnetic prospecting, applied on Grumentum, pre-Roman and Roman city, with an important phase dated to Late Antiquity, of the ancient Lucania, in Basilicata region. The data were processed individually and then integrated with each other in order to recover as much information as possible from the different signals. Due to the qualitative and quantitative approaches to the integration and fusion of the diverse data sets and features, it was possible to detect some urban blocks (insulae) reasonably referable to the Roman age, although obviously not datable, and other features spatially linked to the late antique/early medieval church. Grumentum’s experience shows considerable potential as well as limits in the use of the image fusion-based approach for the enhancement of archaeological features, from which emerges the need to continue experimenting these approaches on a greater number of case studies.

This paper is focused on the archaeological area of Metaponto (Mexomov-nov) and its territory, located in southern Italy. The area played an important role for the agricultural economy and the traffic of goods and people, from the south of Italy towards the central regions, starting from the Neolithic period, and reaching the zenith with the Greek polis of Metaponto and its hinterland. The site is herein analyzed through an integrated use of several Earth observation and remote sensing technologies and ancillary data produced over the years by archaeologists and scholars. The aim was to identify new buried elements of archaeological interest, for the reconstruction of the historical-archaeological landscape. Through the combined use of optical and radar satellite images, high-resolution images obtained by Unmanned Aerial System (visible, multispectral, and thermal infrared), geophysical data, and archival data, it was possible to deepen the knowledge of the area, in particular the “Castrum” area, identifying new buried evidence (structures, roads, and elements of the ancient landscape).
