Best practices for the application of computer vision-based machine learning in archaeology
Defines seven best practices for CV-based ML in archaeology. • Links sources, preprocessing, training, post-treatment and validation. • Shows how to reduce false positives in low-density survey settings. • Integrates explainability, cross-validation and ethical responsibility. • Promotes reproducible, FAIR and archaeologically informed AI workflows
High-performance 3D morphometrics via deep learning and tabular foundation models
This study explores the integration of advanced 3D morphometric techniques and machine/deep learning (ML/DL) for the analysis of complex shapes. In this study, cereal grains were employed to develop a series of complex 3D classification tasks, aiming to improve previous 2D-based classifications of barley grain origins, type, and landrace. Traditional geometric morphometric methods in archaeobotany, typically reliant on 2D data, are expanded here …
Theory and practice of artificial intelligence in archaeology
During the last decade, Machine Learning (ML) approaches have been increasingly adapted to archaeology from related fields, supported by the expansion of open repositories, advances in computational infrastructures, and the fast development of detection, classification and segmentation algorithms. However, the multiplication of ML-based papers can give a false impression of methodological efficiency and general applicability, while masking fundam…
Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features
The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient levees in central Iraq, integrating big multitemporal and multisource satellite datasets with advanced ins…
Over the Hills and Far Away
Archaeologists have long been interested in mobility in the past, but tend to think about and visualize movement in simplified ways that do not account for the range of topographic, environmental, and climatic factors that influenced it. The Iranian Plateau is akin to a number of regions around the globe characterized by dramatic diversity in topography, natural resources, and climate that present local and regionally varied affordances and restr…

Late Bronze – Early Iron Age Agro-systems in Northern Greece
Coastal Landscapes at Palaikastro, Eastern Crete, from the Late Neolithic to the Bronze Age and Historical Periods
Integrating legacy survey data into GIS‐based analysis
Surface archaeological survey has been widely established as the principal method for the regional study of Mediterranean diachronic landscapes. Before the introduction of GPS and digital, GIS‐based recordings in the late 1990s, survey projects employed analogue recording strategies (e.g. personal notebooks, printed forms and cartographic materials) resulting in low‐precision spatial datasets. These archives, termed here as legacy survey data, ca…
Deep learning-based detection of qanat underground water distribution systems using Hexagon spy satellite imagery
Qanats are a remarkable type of ancient hydraulic structure for sustainable water distribution in arid environments that use subterranean channels to transport water from highland or mountainous areas. The presence of the qanat system is marked by a line of regularly spaced shafts visible from the surface, which can be used to detect qanats using satellite imagery. Typically, qanats have been documented by field mapping or manual digitisation wit…

Landscape footprints of peopling and colonisation from the Late Bronze Age to Antiquity in the coastal hinterland of Emporion-Emporiae , NE Iberia
The Empordà plain attests to a remarkable mixture of Late-Holocene cultural exchanges and colonial processes. This includes the founding of Emporion, the earliest Greek colony in Iberia, and of the Roman city of Emporiae. This study aims at assessing landscape changes related to indigenous and colonial settlement in this unique scenario where the shaping of cultural landscapes occurred within a dynamic coastal ecosystem. We carried out a high-tem…

Structuration et occupation de la plaine littorale d’Empúries dans l’Antiquité
Cette contribution traite de l’étude des espaces agraires antiques, de l’occupation du sol et du phénomène de la centuriation dans la plaine littorale de l’Empordà (nord-est de la Catalogne). Caractérisée par des interactions socio-environnementales complexes, la plaine littorale de l’Empordà est marquée par la présence de vastes espaces atterris et de milieux humides liés aux inondations fluviales ainsi que par celle de cordons littoraux. Des ap…
Mediterranean polyculture revisited
This paper examines agriculture, farming and dietary resources in east Crete, and re-evaluates the role of grape and olive in its prehistoric economy, these being key in debates on the emergence of social complexity. To do so bioarchaeological, paleoenvironmental and landscape survey data from the Bronze Age town at Palaikastro and its territory are combined. The results indicate a highly compartmentalised landscape, including intensive crop cult…
Potential of deep learning segmentation for the extraction of archaeological features from historical map series
Historical maps present a unique depiction of past landscapes, providing evidence for a wide range of information such as settlement distribution, past land use, natural resources, transport networks, toponymy and other natural and cultural data within an explicitly spatial context. Maps produced before the expansion of large-scale mechanized agriculture reflect a landscape that is lost today. Of particular interest to us is the great quantity of…

Automated detection of archaeological mounds using machine-learning classification of multisensor and multitemporal satellite data
Significance This paper illustrates the potential of machine learning-based classification of multisensor, multitemporal satellite data for the remote detection and mapping of archaeological mounded settlements in arid environments. Our research integrates multitemporal synthetic-aperture radar and multispectral bands to produce a highly accurate probability field of mound signatures. The results largely expand the known concentration of Indus se…
A brave new world for archaeological survey
Archaeological pedestrian survey is one of the most popular techniques available for primary detection of archaeological sites and description of past landscape use. As such it is an essential tool not just for the understanding of past human distribution, economy, demography and so on but also for cultural heritage management and protection. The most common type of pedestrian surface survey consists of fieldwalking relatively large tracts of lan…
Reconstruction of Caprine Management and Landscape Use Through Dental Microwear Analysis
This paper presents the results of a pilot study using dental microwear analysis on 23 sheep and goat teeth dated to the 6th century BC from the Iron Age site of El Turó Font de la Canya (Barcelona, Spain). This study aimed to reconstruct livestock management practices and landscape use. The dental microwear pattern indicates that sheep and goats could have been grazing in the same area where vegetation was composed of shrubs, bushes and non-gram…
Toward a Definition of Minoan Agro-Pastoral Landscapes
Agricultural production and the palatial redistribution of staples have played a key role in the debate concerning the emergence of social complexity in Minoan Crete. However, much of the focus has fallen on major settlements where such products were consumed, rather than on the landscape where agricultural surplus was produced. While there is no shortage of landscape surveys on Crete, their emphasis has typically been on the distribution of rura…
Environmental evolution and mid–late Holocene climate events in the Valencia lagoon (Mediterranean coast of Spain)
Integration of geomorphological, stratigraphic, malacological, sedimentological and micropalaeontological techniques and 14 C dating allows us to characterise the processes and evolution of the coastal barrier–lagoon system of Valencia (Spain), from the middle Holocene to the historical epoch, as well as the responses to global climate events. Four stages are recognised. Phase 1: around 8240 ± 80 cal. yr BP, a brackish lagoon of moderate energy a…

Photogrammetric re-discovery of the hidden long-term landscapes of western Thessaly, central Greece
Reconstructing the Roman London flavourscape
Using archaeobotanical data and examining them with a novel combination of density interpolation surfaces and social and spatial network analyses, this study has brought together exotic food plants in Roman London to outline the changing ‘face’ of its flavourscape, and contextualise it within the broader exotics commerce in Britannia. Consumption of a variety of exotics appeared to be widespread since the very first stages of London's establishme…

Tracing the history of highland human management in the eastern Pre-Pyrenees
Although high mountain areas have traditionally been viewed as predominantly grazing areas, with low population and a high degree of land-use stasis, recent research suggest that land-use complexity and change over time has been underestimated. This interdisciplinary palaeoenvironmental analysis has been carried out on the Pradell calcareous fen, located in the eastern Pre-Pyrenees (Spain) at 1975 m a.s.l., and it comprises different environmenta…
Pitch production during the Roman period
The authors' research project in the Pyrenees mountains has located and excavated Roman kilns for producing pitch from pine resin. Their investigations reveal a whole sustainable industry, integrated into the local environmental cycle, supplying pitch to the Roman network and charcoal as a spin-off to the local iron extractors. The paper makes a strong case for applying combined archaeological and palaeoenvironmental investigations in upland area…

The Roman Centuriated Landscape
Although centuriation was only one system of Roman land division, its impact on the landscape and its visibility in modern field arrangements make it the most commonly recognized expression of Roman landscapes. Centuriated grid systems are usually analyzed from a materialistic point of view and consequently are regarded as an assertion of Roman dominance over conquered territories. In this sense, their productive function is clear. The hinterland…
Contemporary Engagements Within Corridors of the Past
In a medieval Barcelonan side street, urine, rubbish and a bewildering array of graphic imagery splatters the narrowing walls between two major thoroughfares. A contemporary conflict between residents, unknown artists and others is played out using banners, bottles, stickers, posters, stencils, spray paint and bodily substances. In this shadowy liminality, local and global debates are superimposed upon substructures constructed from disease, pros…

Legacies of Change
Human conceptions of landscape have influenced the shaping of landscapes as much as landscape configurations have modelled human perceptions. In this article a new theoretical approach to long‐term cumulative landscape change is tested on the Garraf Massif (Baix Llobregat, north‐eastern Spain). Thanks to its ancient occupation, physical character and location near to the city of Barcelona, the area provides a good illustration of how human‐induce…
