“…Considering previous studies, masts can be classified into two types: (i) light masts which can be supported and moved by one or two operators (Martínez et al, ; Martínez et al, ; Ortiz et al, ) and (ii) robust masts which must be stationed on the ground (Blockley & Morandi, ; Mozas‐Calvache et al, a). The use of light masts implicates a reduced height of the camera (up to 6 m), while the use of robust masts can increase the height up to 10 m. However, the use of robust masts increase the difficulties of movement and as a consequence the efficiency of the survey.…”

“…However, the number of images needed to cover a zone is incremented with the reduction of the distance to the object. Previously to the development of UASs, some approaches had been implemented in order to lift cameras, such as using balloons (Altan, Celikoyan, Kemper, & Toz, ; Bitelli, Tini, & Vittuari, ; Fotinopoulos, ; Mihajlovic, Mitrovic, Cvijetinovic, & Vojinovic, ; Mozas‐Calvache, Pérez‐García, Cardenal‐Escarcena, Mata‐Castro, & Delgado‐García, b), blimps (Gómez‐Lahoz & González‐Aguilera, ), kites and helikites (Verhoeven, Loenders, Vermeulen, & Docter, ; Verhoeven, Taelman, & Vermeulen, ), paramotors (Faustmann & Palmer, ) and tripods or masts (Blockley & Morandi, ; Georgopoulos, Karras, & Makris, ; Martínez, Ortiz, & Gil, ; Martínez, Ortiz, Gil, & Rego, ; Mozas‐Calvache et al, a; Ortiz, Gil, Martínez, Rego, & Meijide, ). A wider analysis of these techniques was performed by Verhoeven ().…”

Three-dimensional (3D) modelling of archaeological sites has recently undergone a great development due to the implementation of new acquisition devices and techniques and new processing algorithms. One of the most noteworthy of these is the use of unmanned aerial systems for lifting acquisition devices such as digital cameras to model sites based on photogrammetric techniques. Despite the development and wide use of these systems there are some situations where they are not allowed to fly. In this context we propose a method based on masts which elevate the camera in order to perform photogrammetric surveys of large archeological sites. In this study we analysed the photograph acquisition parameters and the surveying procedure in order to balance in-field the efficiency and the complete coverage of photographs in the study zone, taking into account the requirements of the photogrammetric processing technique to be implemented. The proposed method has been applied to a large and complex archaeological site located in Aswan (Egypt). The results obtained (photogrammetric products and the 3D model) have demonstrated the viability of the method in these cases and the possible implementation of these types of studies for documentation, planning, virtual visualization, etc.

“…All the acquisitions on site were made with terrestrial photogrammetry, taking advantage of a custom-built structure consisting of a telescopic mast (Blockley et al, 2015). Some other images were extracted from a video filmed by a drone to document the workings of the hydroelectric plant; the frames of this video, even if done for different purposes, were very useful, once reprocessed, to contextualize the archaeological structures in landscape.…”

Commission IIKEY WORDS : Emergency survey, Digital recording method, Close range photogrammetry, Virtual archaeology, AR and VR for CH ABS TRACT:The research is an analysis of the recording, reconstruction and visualisation of the 3D data of a XVIII century watermill, identified in an emergency archaeological excavation during the construction of the mini-hydroelectric plant on the bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy ). The work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage aimed to increase the research, maintenance and presentation with interactive products. The use of three-dimensional models managed through AR (Augmented Reality) and VR (Virtual Reality) technologies with mobile devices gives several opportunities in the field of study and communication. It also improves on-site exploration of the landscape, enhancing the "minor" archaeological sites, daily subjected to numerous emergency works and facilitating the understanding of heritage sites. INTRODUCTIONThis research is an analysis of the recording, processing reconstruction and visualisation of the 3D data of a XVIII century watermill identified in an emergency archaeological excavation. The discovery, unearthed during the construction of the minihydroelectric plant, is located on the left bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy).The aim of the paper is to show the possibilities offered by digital technologies, mostly the digital photogrammetry and the virtual archaeology, to record and enhancing the "minor" archaeological sites that are daily subjected to numerous emergency surveys over the entire territory. M ost of these interventions consistently produce vast amounts of data that are often confined to the archives and therefore not accessible to the public. * Corresponding authorThis work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage to increase the divulgation and visualisation with interactive products. During fieldwork, the methodology and software employed were very sustainable, intended at surveying the site and considering the issues related to the disclosure of the acquired and processed archaeological data; in this way the collected information could be understood not only by scholars and professionals, but also by a larger audience.The paper presents furthermore a case study, replicable in other emergency excavations sites, where archaeological remains, discovered as a result of urban works, are acquired and processed directly on the place of occurrence, non-invasively and through the use of low cost technologies.

“…So some alternative procedures, such as the use of wide angle lens (Gómez-Lahoz, González-Aguilera, 2009;Mozas et al, 2012;Martínez et al, 2013;Fiorillo et al, 2016), fisheye lens (Boulianne et al, 1997;Kedzierski, Waczykowski, 2007;Georgantas et al, 2012;Covas et al, 2015;Perfetti et al 2017;Barazzetti et al, 2017b) and 360 degrees cameras (Pérez-Ramos, Robleda-Prieto, 2016;Kossieris et al, 2017;Mandelli et al, 2017;Barazzetti et al, 2017a;Fangi et al, 2018;Cantatore et al 2020;Bertellini et al, 2019) were implemented in order to reduce the quantity of images needed to cover the object. The use of Remotely Piloted Aircraft Systems (RPAS) (Colomina, Molina, 2014;Nex, Remondino, 2014;Campana, 2017) and masts (Georgopoulos, 1999;Mozas-Calvache et al, 2012;Martínez et al 2013;Ortiz et al, 2013;Blockley, Morandi, 2015;Martínez et al, 2015;Pérez et al, 2019;Mozas-Calvache et al, 2019) to lift cameras supposes a useful alternative to photographs acquired from the ground because of the improvement of the coverage of the object (usually on the terrain) and the reduction of the occlusions (e.g. those caused by the presence of vertical walls).…”

Abstract. This study describes the methodology carried out and the main results achieved when using photogrammetry and Terrestrial Laser Scanning (TLS) to obtain 3D models of the evolution of archaeological works in Egyptian tombs. More concretely, the study was performed in the exterior zone of the QH34 set of tombs located in the necropolis of Qubbet el-Hawa (Aswan, Egypt). The necropolis is composed of tens of rock-cut tombs located in a medium-size hill situated on a bank of the Nile River. The QH34 zone concentrates a great quantity of tombs from several periods of ancient Egypt. The area of study is situated on a horizontal platform of the terrain of about 300 m2. Thanks to the particular geology of this zone, with a fracture that caused the collapse of part of the rocks, much of these tombs have remained intact because the remains of the collapsed terrain hid their entrances. The archaeological works were carried out during two periods (2018 and 2019 campaigns). The main goal of this study was to model the evolution of these works using several geomatic techniques and obtaining several 3D models of the terrain and burial elements to document the previous, intermediate and final status and to analyse the archaeological works undertaken. In addition, a reduced time was demanded for the acquisition of data. The methodology developed has demonstrated its viability for performing multi-temporal studies in order to document the evolution of the excavation, providing a wide and reliable set of geomatic products.
