This article introduces a low-budget approach to archaeological land surveying using spherical cameras, developed for contexts where drone photography is unavailable or where UAV regulations impede its use. The technique combines a 360° camera with standard accessories, making it affordable, portable, and deployable on demand across varied logistical conditions. It has proven to be quicker, more detailed, and more accurate than EDM-based survey sampling, and it produces results comparable to drone-based photogrammetry in terms of Ground Sample Distance, with the added capability to generate orthomosaics and vertical shots. This methodological article describes technology, equipment, and workflow, and it presents two case studies in which the technique was successfully tested and validated: Tell F6 (Failaka, Kuwait) and the Roman fort at Hiw (Qena, Egypt)—two sites with complex topography, under 4 ha, and with no or scarce vegetation. Quantitative results from both sites are reported, including the GCP RMSE value. We discuss the advantages and limitations of the technique, with the objective of proposing a reproducible, affordable, and legally viable method for archaeological topographic documentation when conventional remote sensing tools are unavailable.

Photographed over more than two decades, alterations to the Alto Caramucho geoglyphs in the Atacama Desert show the unfolding of a heritage disaster. This article presents research that integrates new digital technologies (photogrammetry and artificial intelligence) for the evaluation and documentation of the deterioration of the geoglyphs.

Throughout the precolonial era, monumentality in the midcontinent was expressed through a variety of earthen constructions from circular mounds to animal effigies to geometric shapes to depictions of spiritual beings. Here, we describe an example of megalithic monumentality located at the Menominee Reservation in Wisconsin, USA. This archaeological feature uses a mix of the natural geology alongside anthropogenic efforts to depict the Menominee legend of a battle between the Thunderbird and Serpent. The encountering and documentation of this megalith were the result of ongoing collaborative efforts that brought together archaeological techniques with Menominee knowledge sets. We describe the megalith and draw on the only other known megalithic effigy from Wisconsin, a serpent effigy, located in ancestral Menominee territory and documented more than a century ago. Together, these two megalithic features illustrate currently unrecognized monumental construction efforts in the midcontinent and highlight the value and importance of collaborative approaches to documenting and preserving archaeological heritage.

Coastal, riverine, and lacustrine environments have played a central role in the development of human societies, yet locating and documenting this record of activity in littoral environments have proven difficult. Terrestrial survey methods reach their limit at the water’s edge, whereas marine geophysical equipment often struggles in depths of less than 1 m. This “white ribbon” of missing data represents a persistent methodological gap but one that is rich in information. Recent work on Scottish crannogs, or artificial islands, has highlighted this predicament while also providing a test bed for practical solutions. This article presents the results of that work: a robust and repeatable workflow for high-resolution shallow-water photogrammetry, tested in challenging conditions and benchmarked against the GNSS-enabled accuracy of drone surveys. The approach combines stereophotogrammetry, using artificial scale bars for internal calibration, with ground control points to enable the integration of terrestrial and underwater data. This method is both accessible and efficient, offering a replicable framework for recording archaeological sites at the water’s edge.

In this article we present a methodological framework for integrating nondigital legacy excavation data with modern stratigraphic datasets in a 3D-GIS environment. Using a case study from the Late Bronze Age site of Hala Sultan Tekke (Cyprus), we demonstrate how georeferenced photogrammetric models can be combined with digitized legacy documentation to overcome inconsistencies in archival records. The approach enables the correction of elevation data, the reconstruction of stratigraphic layers that are no longer preserved, and the interpolation of missing contexts. By aligning old section drawings with high-resolution 3D models of recent sondages, we created a coherent spatial and chronological framework that facilitates new archaeological interpretations. This integrated model also supports cross-disciplinary collaboration and long-term digital preservation. The study contributes to wider discussions on the sustainable use of unpublished or fragmentary excavation records, offering a practical, step-by-step guide for researchers working with similar datasets. Ultimately, this approach underscores the potential of 3D modeling to revitalize underused archaeological archives and transform them into dynamic analytical tools, in line with current best practices in digital archaeology and open data sharing.

This article describes the publication and evaluation of a user-driven narrative module on the public-facing 3D platform Sketchfab, which comprises dozens of interlinked 3D models relating to the archaeology of the Faynan region of Southern Jordan. Models included in the project are archaeological sites, excavation units, and artifacts related to the Iron Age and Islamic period archaeology of the region. By interlinking these models according to their spatial, conceptual, and contextual relationships, this project facilitates the nonlinear exploration of archaeological data and replicates the process of archaeological knowledge generation, in which information is produced through examination of the relationship between object and its provenience. Through the inclusion of bilingual (Arabic and English) text in this project, we aim to increase the accessibility of archaeological data and interpretation to interested parties. We also invite participation in the development of multiple narratives based on user-driven, independent exploration of artifacts and context. Through free navigation within and between models, users can develop their own understanding of the archaeology of Faynan based on research-based content published in 3D. The effectiveness of the project is evaluated here through surveying Arabic-speaking Jordanians, a key group of interested parties.

We present new line drawings of the hieroglyphic inscriptions on Stela 4 (a.d. 796) at the ancient Maya royal capital of Ixkun, Guatemala. Lichen growth makes these texts almost illegible in person, but a photogrammetric model, rendered monochrome in Agisoft Metashape and imaged in Blender 3D, permits almost all the glyphs to be read or reconstructed. According to our interpretation, the main inscription records the journey of a prince of Ixkun to be fostered at Tikal, coordinated between the ruler of Ixkun and Yax Nuun Ahiin II, the king of Tikal. We think this arrangement cemented a new alliance between Tikal and Ixkun, in exchange for which the Ixkun king received a newly elevated royal and ritual status. Another text indicates that a prisoner from the neighboring Ho’kab’ kingdom, represented six years earlier on Stela 1, had survived in captivity for at least that long.

Quarries are information-rich anthropic landscapes, but their unique characteristics often limit the effectiveness of traditional archaeological documentation strategies. Here, the authors present a novel interdisciplinary method for the documentation and analysis of these landscapes, focusing on two ancient marble quarries on the Mediterranean island of Naxos. The workflow, combining lidar, photogrammetry, sculptural and architectural study, geoscience, ecological study and archaeological survey, provides a means for the systematic documentation of quarry landscapes in the Mediterranean and beyond, and aims to promote an understanding of premodern extractive activities not as isolated occurrences but as important aspects of interconnected, evolving landscapes.

This article presents an innovative workflow for the acquisition and storage of archaeological data. The system is based on open-source software to enhance method replication and media accessibility. QGIS software is used as the central platform, connected to a spatial database developed in PostgreSQL and managed with the SQL and Python programming languages. The aim is to achieve an efficient, flexible, and reproducible digital method for data collection and management that can be applied to surface archaeological surveys. During the implementation and development of the method, we have recorded over 4,600 archaeological remains in two different structures with traces of Upper Paleolithic activity in the Lower Gallery of La Garma (Cantabria, Spain). After 18 months of continuous work, the results obtained demonstrate the usefulness and versatility of this procedure, which can be adapted to each context and to the specific needs of each researcher. Our goal is not simply to systematize archaeological documentation, as traditionally proposed, but to establish a simple and robust method for data collection and preservation, accessible to any user. Its fully open-source approach aims to promote a model that is nurtured by the use and contributions of the research community.

It remains a little-known fact that from March 1766 to May 1767 Jean-Jacques Rousseau – fleeing from persecution in France and Switzerland – stayed in the remote hamlet of Wootton in Staffordshire. There he composed the first half of his Confessions in a garden hermitage, a structure half natural and half architectural, ever since known as Rousseau’s Cave. Our paper records the hermitage in its current state (exposed to the elements); it creates a digital reconstruction of the hermitage as it was in Rousseau’s lifetime; and it provides digital access to a monument that is otherwise not generally accessible.

Our paper records a modest but fairly typical eighteenth-century garden hermitage and also, with the highest quality digital reconstructions and fly-throughs, provides a new insight into the creation of one of the world’s greatest works of literature.

The paper contributes substantial new material to the study of Jean-Jacques Rousseau and also contributes to garden history and the phenomenon of the garden hermitage.

The tattoos of the Pazyryk ice mummies are of paramount importance for the archaeology of Iron Age Siberia and are often discussed from a broad stylistic and symbolic perspective. However, deeper investigations into this cultural practice were hindered by the inaccessibility of quality data. Here, the authors use high-resolution, near-infrared data in conjunction with experimental evidence to re-examine the tools and techniques employed in Early Iron Age tattooing. The high-quality data allow for the previously unfeasible distinction of artist hands and enable us to put the individual back into the picture of a widespread but rarely preserved prehistoric practice.

The long-term development of coral reef frameworks and the net vertical accretion of reefs fundamentally underpins the provisioning of most reef-related ecosystem services. One area of particular concern at present is how rates of reef accretion are changing under ecological decline and what the consequences of this may be for the capacity of reefs to keep pace with near-future sea-level rise (SLR). This may have major implications for the capacity of reefs to maintain their coastal protective functions and to support reef island stability. Both are issues relevant to understanding future tropical coastal risk. Long-term (millennial timescale) rates of reef accretion are relatively well constrained, including through past periods of sea-level fluctuations. However, widespread and persistent ecological degradation of coral communities has caused many reefs to diverge significantly from their past accretion trajectories. This renders historical analogues increasingly unreliable for projecting future accretion potential. Addressing this necessitates a reorientation towards considering reef accretion rates across shorter (ecological to geomorphic) timescales, i.e., over years to multi-decades. This is essential if we are to better constrain contemporary reef accretion rate and SLR interactions at timescales relevant to predicting emerging coastal risks and understanding future implications for reef-derived benefits. Here, we review existing approaches for quantifying vertical reef accretion rates of modern reefs. These methods span data recovered from fossil outcrops or core-derived records, the conversion of carbonate budget data, direct in situ measurements and emerging remote sensing and image-based techniques. The review explores the advantages and limitations of these different approaches and outlines options for developing an integrated framework to link past, present and future reef accretion potential.

The nature and extent of interactions between the distant regions and cultures of Mesoamerica remain open to much debate. Close economic and political ties developed between Teotihuacan and the lowland Maya during the Early Classic period (AD 250–550), yet the relationship between these cultures continues to perplex scholars. This article presents an elaborately painted altar from an elite residential group at the lowland Maya centre of Tikal, Guatemala. Dating to the fifth century AD, the altar is unique in its display of Teotihuacan architectural and artistic forms, adding to evidence not only for cultural influence during this period, but also for an active Teotihuacan presence at Tikal.

Recent research on the organisation and growth of large settlements (both urban and non-urban) has prompted a reassessment of factors driving population aggregation. Systematic aerial and ground survey of the South Caucasus mega-fortress Dmanisis Gora, described here, contributes to the understanding of large fortress settlements in the South Caucasus (c. 1500–500 BC) as part of this wider debate. Substantial defensive walls and stone architecture in the outer settlement contrast with low-intensity occupation, possibly by a seasonally mobile segment of the population. The exceptional size of Dmanisis Gora helps add new dimensions to population aggregation models in Eurasia and beyond.

La Milpa, situated in northern Belize, stands out as one of the region's largest archaeological sites, having served as the capital of an ancient Maya city-state. Its significance is indicated by extensive monumental architecture, with the epicenter covering approximately 8.8 ha. The site's corpus of monuments, comprising 23 stelae and several altars, underscores its prominence in northern Belize, rivaling the corpora of sites such as Nim li Punit and Caracol. Despite its remote location, La Milpa has garnered the attention of researchers, particularly since the first modern survey of the site in 1988. Subsequent studies—in particular, that by Nikolai Grube in the 1990s—has provided detailed analyses of the site's corpus of carved monuments. Recent efforts, including epigraphic documentation in 2019, serve to enhance our understanding of La Milpa's dynastic history through traditional epigraphic and computational photographic methods. Utilizing field observations, raking light photography, and 3D photogrammetric models, we have refined previous analyses and provide new insights into the iconography and textual segments of the monuments. Here, we present the results of these recent efforts as well as our new analyses of a selection of monuments.

The Central Mediterranean Penal Heritage Project (CMPHP) employs remote-sensing techniques to study and preserve archaeological remains of human confinement. Within this larger project, digital photogrammetry was used to document part of the castle prison in Noto Antica to identify and digitally preserve graffiti depicting galleys and gameboards.

In the summer of 2022, Tulane University, in collaboration with archaeologists from other institutions, began excavations at the site of Pompeii. The archaeological work was focused on Insula 14 of Region 1, located in the southeastern sector of the site. To overcome the challenges of recording a complex urban excavation, and of working with a collaborative team, we designed and implemented a unique workflow that combines paperless and 3D data-capture methods through the use of GIS technologies. The final product of our documentation workflow was a robust and easy-to-use online geodatabase where archaeologists can revisit, explore, visualize, and analyze each excavated context using virtual tools. We present our workflow for digitally documenting observational and spatial data in the field, and how we made these data available to project archaeologists during and after the field season. First, we describe the development of digital forms in ESRI's Survey123. Then, we explain our procedures for 3D documentation through SfM photogrammetric methods and discuss how we integrated the data and transformed it into an accessible format by using interactive dashboards and online 3D web scenes. Finally, we discuss the components of our workflow that are broadly applicable and that can easily be adapted to other projects.

The military invasion of Ukraine has destroyed and damaged extensive built cultural heritage, including churches, museums and monuments. Based on site visits conducted since the invasion, we outline damage to the eleventh-century sites of Boldyni Hory, Chernihiv, and the church, citadel and graveyard at Oster, Chernihiv Oblast.

Debate surrounds the identity of the Europeans who settled Iceland and Greenland in the early medieval period. Historical sources record settlers travelling from Norway to Iceland and then Greenland, but recent analyses of biological data suggest that some settlers had British and Irish ancestry. Here, the authors test these hypotheses with 3D-shape analyses of human crania from Scandinavia, Britain and Ireland, and one of the Norse colonies in Greenland. Results suggest that some 63 per cent of the ancestry of the Greenlandic individuals can be traced to Britain and Ireland and 37 per cent to Scandinavia. These findings add further weight to the idea that the European settlers who colonised Iceland and later Greenland were of mixed ancestry.

We present a photogrammetric model and new line drawing of Sacul Stela 3 at the ancient Maya site of Sacul 1, Guatemala. Although virtually illegible in person and from photographs, the inscription on the eroded stela can largely be read or reconstructed in the 3D model. Our reading confirms a previous argument that the kingdom based at Sacul 1 was attacked in A.D. 779 by forces from the site of Ucanal. Traveling by night, warriors from Sacul retaliated with a raid at dawn next day on an unidentified site and, months later, followed up with an attack on Ucanal itself. The same narrative appears substantially on a well-known monument, Ixkun Stela 2, but there are differences between the two texts which suggest that Sacul and Ixkun had their own sculptors and record-keepers and which offer insights into the implications of verbs (pul, “to burn” and ch'ak, “to chop”) commonly attested in Classic Maya accounts of war. We then present the results of GIS analysis which suggests that the site area of El Rosario (between Sacul 1 and Ucanal) is an appealing candidate for the unidentified site mentioned in the stela text.
