This paper presents a multi-analytic study conducted as part of the IDHEA project at the former Tuna Factory Florio, an architectural complex situated on the captivating island of Favignana within the Egadi Islands, Trapani, Sicily, Italy. As a 19th-century industrial archaeology pole, this site stands as an intriguing nexus of architecture, museum exhibits, and cultural significance, rendering it an ideal experimental ground for pioneering methods and technologies aimed at preserving, managing, and enhancing cultural heritage. Given its coastal location, the structures are highly susceptible to marine, geomorphological, and environmental threats, intensifying material degradation risks. In this study, different approaches were adopted for the inspection, decay assessment and architectural survey of the building complex, including 3D architectural surveys via terrestrial laser scanning, drone-based RGB photogrammetry, multispectral data collection, and direct inspections. This integration yields comprehensive data and intricate 3D models, aiding in pinpointing specific vulnerabilities. The study culminates in the implementation of a GIS platform that harmonizes all data, serving as a pivotal resource for managing and preserving this historically significant site.

Thanks to the analysis of some recent satellite images, within a CNR-ISPC research project aimed at the realization of a Historical Aerotopographic Atlas of the ancient city of Albania, it is possible to present a preliminary study of two important ancient cities of Albania, Apollonia and Phoenike, aimed at enhancing some aspects of urban topography. In particular, historical space photos and recent satellite images were particularly useful for identifying traces likely to refer to buried buildings or parts of buildings, in sectors of archaeological areas where archaeological excavations have not yet been conducted.

Lecce s historical character is expressed by its historical centre, rich in cultural and architectural marvels of the past. However, the symbol of Lecce s ancient origins is the Roman amphitheatre in St. Oronzo square, the core of the city. The amphitheatre was discovered during the construction of the building of the Bank of Italy by some workers in the early 900. In order to have pieces of information related to the structure of the amphitheatre, geophysical surveys were undertaken inside and outside it. In this paper, some of the interesting results obtained will be presented.

The potential of GIS applications has been successfully applied in the most diverse fields for years, starting from urban planning to geology, from agriculture to cultural heritage, and from engineering to architecture. Through GIS systems, territorial information can be entered in a single container that allows not only to save and preserve them but also to study and process them. This GIS for the systematic filing of the dovecotes present in Salento in Puglia, implements GIS analysis technologies. With them the common characteristics of the architectures are immediately highlighted, thus creating tables which, converted into special formats, dynamically connect the artefacts and the thematic segments: a precious source for an innovative analysis tool, in terms of conservative recovery and subsequent enhancement of the entire system of dovecotes present in Salento.

The Roman amphitheater of Venosa (Potenza, southern Italy) is one of the experimental sites chosen as part of the IDEHA project (Innovation for Data Processing in Heritage Areas) in the Basilicata region, of which the CNR ISPC was scientific coordinator. This contribution presents the new results of the research more closely linked to the technical and constructive aspects of the monument, achieved starting from the instrumental survey performed with integrated techniques of laser scanning and digital photogrammetry. The metric data collected was integrated with those no longer visible that emerged during the archaeological excavation campaigns, which took place in 1841, 1925 and then in the 1980s and from a careful reconnaissance of the collapsed architectural elements present in situ. Despite the poor conditions of the wall structures, subject to centuries of abandonment and spoliations, it was possible to develop a reconstructive proposal for the amphitheater, with the creation of a three-dimensional model in which they critically merged all the collected data.
