Proceedings of the 48th Conference on Computer Applications and Quantitative Methods in Archaeology Kyriakidis, Phaedon; Agapiou, Athos; Leventis, George These proceedings bring together a selection of papers and posters presented at the 48th Conference on Computer Applications and Quantitative Methods in Archaeology (CAA), one of the leading international forums for the exploration of digital and quantitative approaches in archaeological research. The conference theme, “Digital Crossroads,” was selected to reflect the original intention to host the event in Limassol, Cyprus, the third-largest island in the Mediterranean and a place that has occupied a pivotal position at the crossroads of civilisations since prehistory. Beyond its geographical resonance, the theme also captures the broader intellectual and methodological moment in which archaeology and related disciplines now find themselves, as ongoing digital transformation continues to reshape the ways in which the past is investigated, interpreted, and communicated. The cultural heritage of Cyprus and the wider Eastern Mediterranean constitutes an exceptional historical, social, and economic resource. At the same time, this heritage remains particularly vulnerable to the effects of conflict, political instability, and other regional pressures. In this context, the protection, preservation, and promotion of cultural heritage, together with the study of long-term social and human–environment interactions, provide a particularly fertile framework for the development and application of quantitative methods and digital technologies within contemporary archaeological scholarship. Although the Local Organising Committee had very much hoped to welcome participants to Limassol in June 2021, the COVID-19 pandemic ultimately rendered an in-person meeting impossible. Nevertheless, it was both a privilege and a pleasure to host this important annual gathering of the CAA community in an online format, ensuring the continuation of scholarly exchange and international collaboration during an exceptionally challenging period. We wish to express our sincere gratitude to the members of the Scientific Committee, the officers of CAA International, the Cyprus University of Technology, and our local supporters. Their dedication, collaboration, and generosity were instrumental in making this event possible. 2026-05-01T00:00:00Z http://hdl.handle.net/10900/174135 Digital Technologies Applied to Antarctic Archaeology: An Overview da Silva Martire, Alex; Zarankin, Andrés; Codevilla, Fernanda Since 2009, the Laboratory of Antarctic Studies in Human Sciences (LEACH) at the Federal University of Minas Gerais (UFMG) in Brazil, has been dedicated to the research and mediation of Antarctic archaeology from the perspective of Public Archaeology. The international project ‘White Landscapes: Archaeology, Anthropology, History and Conservation of Human Occupation in the South Shetland Islands, Antarctica’ , under development by the LEACH-UFMG team, aims to understand the human occupation strategies of the last continent throughout history. In this context, the main objective of this work is to present the digital approaches of LEACH-UFMG in three concomitant aspects: 1) applied to the archaeological field in Antarctica during excavations undertaken on-site (3D laser scanning of remains and landscapes, drone captures , and data logging on tablets); 2) applied to artefacts and collections analysed in the laboratory (3D printing, 3D laser scanning and photogrammetry); 3) applied to mediation with the archaeological and non-archaeological public (itinerant sensory exhibition that simulates the Antarctic environment, Virtual and Augmented Reality, and digital video game about the daily life of local sealers and whalers, as well as current archaeological expeditions in territories of Antarctica). Thus, with this work, we aim to demonstrate how we can streamline communication channels between archaeologists and non-archaeologists, encouraging the creation of multivocal narratives about the human occupation of Antarctica. 2026-03-01T00:00:00Z http://hdl.handle.net/10900/174134 Towards a workflow for documenting, processing and archiving large excavation contexts on-the-fly: challenges and lessons learnt at the Palace of Nestor Project, Pylos Putzolu, Cristiano; Wallrodt, John; Stocker, Sharon; Davis, Jack Photogrammetry constitutes a key part of the excavation workflow for The Palace of Nestor Excavations (PONEX). Since May 2018, the PONEX project has been engaged in the excavation of two monumental stone-lined tholos tombs: each tomb is documented using high-resolution photogrammetry every few days and the total number of models generated by the project now numbers in the hundreds 100s. This discursive paper discusses the particular challenges faced by the PONEX project with regard to the acquisition of 3Dd documentation. The first challenge is one of scale. To produce a set of usable models of such large and complex contexts on a regular programme presents both technological and practical challenges. The goal of the project is to process all 3Dd models ‘on-the-fly’, such that there is no backlog of processing left at the end of excavation seasons. This second challenge concerns division of labour and the availability of project staff. Particularly during the COVIDcovid-19 pandemic, there was a need to compartmentalise tasks and to train non-specialists to gather data or run basic data processing tasks when specialists were not present. Remote working has always been an important part of the PONEX workflow, specifically with regard to data archiving. The PONEX project is just one of many that now use photogrammetry documentation, but the wider implication of this case study is in demonstrating how and why workflows can be adapted according to the specific needs of a project’s scope and workforce. 2026-03-01T00:00:00Z http://hdl.handle.net/10900/174133 ART3mis: Ray-based textual annotation on 3D cultural objects. Arampatzakis, Vasileios; Karamatskos, Dimitrios; Sevetlidis, Vasileios; Arnaoutoglou, Fotis; Kalogeras, Athanasios; Koulamas, Christos; Lalos, Aris; Kiourt, Chairi; Ioannakis, George; Koutsoud, Anestis; Pavlidis, George P. Beyond simplistic 3D visualisations, archaeologists, as well as cultural heritage experts and practitioners, need applica-tions with advanced functionalities. Such as the annotation and attachment of metadata onto particular regions of the 3D digital objects. Various approaches have been presented to tackle this challenge, most of which achieve excellent results in the domain of their application. However, they are often confined to that specific domain and particular problem. In this paper, we present ART3mis – a general-purpose, user-friendly, interactive textual annotation tool for 3D objects. Primarily attuned to aid cultural heritage conservators, restorers and curators with no technical skills in 3D imaging and graphics, the tool allows for the easy handling, segmenting and annotating of 3D digital replicas of artefacts. ART3mis applies a user-driven, direct-on-surface approach. It can handle detailed 3D cultural objects in real-time and store textual annotations for multiple complex regions in JSON data format. 2026-03-01T00:00:00Z
