Often interpreted as 'proto-towns', the authors present results of investigations at Monte Santa Croce-Cognolo that challenge this idea. Previous studies identified a small area (<1ha) of occupation and suggested that habitation extended across the whole 18ha site. Combining geophysical and pedestrian survey with remotely sensed data, and local ethnographic accounts, the authors detect little evidence for permanent habitation and instead argue for activities connected with animal husbandry. The results challenge urban-centric interpretations by demonstrating the coexistence of monumental but uninhabited hillforts and urban sites-usually seen across the Mediterranean and Europe.

However, the representativeness of these datasets in accurately reflecting the surviving distributions of archaeological sites has often been overlooked. This paper discusses issues of sampling and representativeness in LiDAR-derived datasets, particularly within the scope of large-scale landscape studies in Mediterranean contexts. Drawing insights from the Ancient Hillforts Survey, which analysed 15 296 km 2 in south-central Italy, the study examines the variability in the visibility of different site typologies in open-source but low-resolution LiDAR data. Through an examination of hillforts, platform farms, settlements, field systems, traces of Roman centuriation, and transhumance routes, the paper highlights significant variability in the identification and mapping within and across different site types. Recognizing the need to account for this variability in the development of spatial analysis, the paper discusses the use of sampling areas to address this variability. This approach aims to effectively mitigate potential biases in analysis, emphasizing the necessity for nuanced methodologies in interpreting LiDAR data for archaeological research.

Given the difficult terrain, the archaeological information currently at our disposal has, as a rule, been collected in a non-systematic way. This hampers comparison and integration within wider, regional landscape archaeological projects. In this paper, we present a field method applied to two mountain sites with different characteristics in the province of Isernia, Molise. The hillfort of La Romana near Castelromano presents monumental walls enclosing an area of c. 20 ha, and is almost fully covered with forest and shrubs. The site of Lo Monaco near Longano, is smaller, with c. 0.6 ha, and has a barren, rocky surface. We applied a systematic point sampling strategy, collecting all finds within circles with a 1 m radius, combined with diagnostic sampling in larger spatial units. We also used various remote sensing and fieldwork methods to map structural remains. This combined method aimed to strike a balance between adaptation to the particularities of different mountain sites, and comparability of the results. We offer a new reconstruction of the walled area(s) of La Romana, and propose a chronological and functional interpretation discerning an Archaic-Hellenistic phase and a Late Roman-Medieval phase. For Lo Monaco, we propose a main Classical-Hellenistic phase of the settlement, and present evidence for (semi)permanent habitation as well as metal-working at the site. We conclude that the point sampling method is labour-intensive, but effective in better understanding the internal configuration and chronological development of mountain sites. Keywords: Samnites; hillforts; mountain archaeology; archaeological survey; remote sensing.

This article presents a statistically grounded method for the comparative analysis of polygonal masonry and the calculation of their architectural energetics. Four wall stretches of different Samnite hillforts (5th-3rd century BCE) have been recorded through 3D modelling to generate models suitable for calculating three variables (area, rectangularity and gap area) used for a comparative assessment of the different building techniques involved in their construction. This allowed the identification of masonry styles related to different costs of labor which were used to produce cross-regional energetic indexes suitable for the cost analysis of several hundred hillforts in south-central Italy. This formal and replicable approach to the cost analysis of polygonal masonry is not only suitable for analysing sites in Italy, but can also be applied to similar sites found widely in the Mediterranean.

Past approaches have been limited by the available means of archaeological investigation, which has hindered the creation of a representative dataset suitable for developing spatial statistical models. The Ancient Hillforts Survey addressed this issue by developing a large-scale LiDAR-led survey that effectively overcomes some of the previous limitations for studying mountainous and forested regions. In this way, it is creating the first representative dataset of hillfort sites in Samnium. The paper discusses this project’s approach and showcases the results obtained for the area of mount Tifata in Campania. New data was collected on both hillforts and the organisation of the landscape, including detecting new traces of Roman centuriation. The results show the effectiveness of the developed approach for studying mountainous and forested regions, landscapes historically understudied by archaeological research, especially in the Mediterranean basin.

An analysis of 15,300 km2 spanning Campania, Lazio, Abruzzo, Molise, and Apulia detected 305 new suspected hillforts. The area was visually interpreted using image blends of lidar visualizations (VAT method) based on in-house-generated digital terrain models. Interobserver and intraobserver interpretational biases were tested and CORINE Land Cover data used to evaluate the representativeness of the legacy data compared with the new dataset and to estimate the number of sites for no-data areas. The results from the Daunian mountains (Apulia) are presented to demonstrate the effectiveness of this approach in advancing knowledge of historically under-surveyed areas and in addressing long-term debates. Here, the data showed a novel hillfort system interpretable as Samnite, dating between the 6th and 3rd century b.c.

The use of semi-automatic methods to detect and extract archaeological objects in LIDAR data is providing outstanding results. For several large areas of the world, however, LIDAR data are not available, and satellite imagery is often the only source of information that archaeologists can use. Therefore, it is necessary to develop new automatisms to analyse satellite imagery. This paper proposes a ruleset developed in eCognition to detect and extract complex burial monuments in Arabia from WorldView-2 satellite imagery. The ruleset is composed of three parts. The first part identifies candidate objects as single pixels using an adaptive template matching algorithm. The second part uses the identified candidate pixels as seeds for a region growing segmentation which creates the borders of the objects. This process is suitable to draw any object automatically because it does not consider any assumption regarding its shape. The third part of the ruleset classifies the candidate objects using a combination of thresholds and a random tree classifier. The adaptive template matching code has been trained using 130 burial monuments located across 3 km2. The same objects have been used to train the random tree classifier together with 200 negative samples. The ruleset was then applied on 100 km2 of terra incognita to test its efficiency. The results of this test are highly significant. This new method was able to detect and extract almost 80% of the burial monuments verified in the area, with an index of false positives equal to 30% of the total detections.

However, its application across the region remains uneven, particularly due to significant variations in data availability. While some countries benefit from comprehensive, large-scale government datasets at different resolutions, others must rely on ad hoc, often drone-based, acquisitions. These disparities directly affect lidar's research potential, shaping its ability to address archaeological questions at both landscape-wide and site-specific levels. The methodological divide between large-scale, lower-resolution lidar and high-resolution, site-focused data presents important considerations for researchers. In countries like Spain, Slovenia and Italy, where extensive datasets are accessible, efforts to identify archaeological sites across vast regions are progressing, supported by machine learning techniques that automate site detection. In contrast, countries that depend on ad hoc data acquisition tend to use lidar at a more localized scale, focusing on detailed analyses of individual sites or smaller portions of the landscape. These studies investigate multiple aspects of the sites rather than concentrating solely on specific site typologies. The uneven availability of lidar data shapes research strategies and creates disparities in its use across the Mediterranean. This session aims to explore how the quality and accessibility of various lidar datasets influence regional research priorities. We welcome contributions on a range of topics, including methodological approaches such as the implementation of machine learning or addressing the challenges of filtering data in densely vegetated areas, as well as specific case studies and broader reflections on how lidar is shaping research and cultural heritage management in different countries. Our goal is to foster dialogue among researchers, encouraging critical reflection on how lidar is reshaping traditional archaeological questions associated with landscape archaeology and driving new research directions in the Mediterranean context.
