“…Through the combination of data acquisition with a 3D laser scanner as well as with drone footage, we were able to cover most of this cultural heritage site. Although it does not completely replace a direct access and study of the remains (Arlaud and Burnouf, 1993;Schuller, 2002;Héno et al, 2010;Boto-Varela et al, 2012;Limp, 2016;Luczfalvy Jancsó et al, 2016). Nevertheless, considering the stability problems and the height complications, it at least enables the cultural heritage actors to virtually study these sections.…”

“…Another factor that had to be kept in mind was the subjective nature of archaeological drawing, one of the most utilized techniques in building archaeology (Arlaud and Burnouf, 1993;Schuller, 2002;Eßer et al, 2011;Boto-Varela et al, 2012;Alby, 2015). Indeed, since an archaeologist would produce a range of information that would also be used later on, he needs to provide documentation that can be exploited for the other goals.…”

“…The following features and usages of this type of 3D digitisation seemed to meet best the needs of a research carried out on a cultural heritage site: objective documentation, multiple visualisation possibilities, various exploitation possibilities, precision, georeferenced model, colorization, distance and angle measuring, plan, cross section and volumetric data extraction as well as possible combinations with other spatial documents and analyses (LiDAR, GIS). These characteristics would enable the researchers and cultural heritage actors to study the evolution of the architecture, the volumes or the spatial relations in and outside of the castle (Arlaud and Burnouf, 1993;Schuller, 2002;Héno et al, 2010;Boto-Varela et al, 2012;Canciani and Saccone, 2012;McManama-Kearin, 2012;Salvador and Vitti, 2012;McManama-Kearin, 2013;De Kleijn et al, 2016). Also, a basic 3D point cloud does not satisfy all of the above mentioned characteristics: for example, the digitisation does not help with missing or not vectorised data all the more if it concerns another type of information other than spatially driven.…”

This paper presents the identified obstacles, needs and selected solutions for the study of the medieval castle of Franchimont, located in the province of Liège (Belgium). After taking into account the requirements from all the disciplines at work as well as the problems that would have to be tackled, the creation of a 3D point cloud was decided. This solution would be able to deal with the characteristics and needs of a research involving building archaeology and related fields. The decision was made in order to manage all of the available data and to provide a common working tool for every involved cultural heritage actor. To achieve this, the elaboration of an Archaeological Information System based on 3D point clouds as a common virtual workspace is being taken into consideration.

“…However, archaeologists will often use such an approach over remote sensing to gather insights that are otherwise considered incomplete. The 3D methods are frequently regarded as intricate, expensive and not adapted to archaeological issues [17]. On most sites, for buildings studies or in excavations, the data gathering and acquisition are made with drawings and pictures in 2D.…”

Digital investigations of the real world through point clouds and derivatives are changing how curators, cultural heritage researchers and archaeologists work and collaborate. To progressively aggregate expertise and enhance the working proficiency of all professionals, virtual reconstructions demand adapted tools to facilitate knowledge dissemination. However, to achieve this perceptive level, a point cloud must be semantically rich, retaining relevant information for the end user. In this paper, we review the state of the art of point cloud integration within archaeological applications, giving an overview of 3D technologies for heritage, digital exploitation and case studies showing the assimilation status within 3D GIS. Identified issues and new perspectives are addressed through a knowledge-based point cloud processing framework for multi-sensory data, and illustrated on mosaics and quasi-planar objects. A new acquisition, pre-processing, segmentation and ontology-based classification method on hybrid point clouds from both terrestrial laser scanning and dense image matching is proposed to enable reasoning for information extraction. Experiments in detection and semantic enrichment show promising results of 94% correct semantization. Then, we integrate the metadata in an archaeological smart point cloud data structure allowing spatio-semantic queries related to CIDOC-CRM. Finally, a WebGL prototype is presented that leads to efficient communication between actors by proposing optimal 3D data visualizations as a basis on which interaction can grow.

The aim of this paper is to present the methodology used to study the megalithic architecture of Menjez’s monuments (Akkar, Lebanon), as part of the MEG-A Project - “First megalith builders in the northern Levant” (2022–2025). Twenty-four monuments have been investigated since 2018. The primary objective is to pioneer a comprehensive understanding of the unique Levantine megalithic building techniques and re-establish the “chaînes opératoires,” by determining the builders’ sequence of actions. This groundbreaking methodology originally developed for Western European megalithic monuments, notably in Brittany, France, has been innovatively applied and customized to suit the Levantine context, specifically focusing on the distinctive basaltic monuments of Menjez and its surrounding areas. By using photogrammetry as a tool, the researchers are able to de-construct the megalithic architecture by analyzing the different components of these monuments. Moreover, it is then possible to describe monoliths according to their place within the monument and their geological and geomorphological features. Our work has led us to consider the symbolic aspect expressed in the megalithic architecture of Menjez. Employing this groundbreaking methodology not only yields concrete answers regarding the typology of these monuments but also dramatically reshapes our perception of their construction. It establishes a precise relative chronology for the various architectural phases and, most significantly, reveals the hidden details of the raw material supply chain.
