Registro tridimensional acumulativo de la secuencia estratigráfica. Fotogrametría y SIG en la intervención arqueológica de lo Boligni (Alacant)

Abstract

<p>In this paper a stratigraphic recording methodology is presented after a practial experience at the lo Boligni archaeological site. This experience has allowed, on the basis of cenital stereo-photo pairs, the digitalization of interfacial surfaces through high density point clouds renderization as the excavation went on, in order to obtain a Three-dimmensional Cummulative Model (TCM) of the stratigraphical sequence. It will be exposed the way some easy and affordable digital tools are used at the excavation in order to achieve a massive data recovery, and how their integration in CAD and GIS environments opens new possibilities for the everyday archaeological information treatement.</p>

Understanding taphonomy through 3D and 2D records: a case study from the tropical Maya area

“…In the 2020s, digital photogrammetry is a relatively cheap technique that only requires a digital camera with reasonable resolution (e.g., 18 megapixels and above) and a medium-quality laptop to produce accurate and well-textured 3D models and precise orthophotos in a matter of hours (Lerma et al, 2010;Pérez García et al, 2011;Pollefeys et al, 2001). Using digital photogrammetry, archaeologists have extensively demonstrated the utility of producing 3D virtual visualization of stratigraphic excavations (Berggren et al, 2015;Charquero Ballester & López Lillo, 2012;De Reu et al, 2013;Howland, 2018;Lercari, 2018;Losier et al, 2007;Nigro et al, 2003). Recently, our team at Palenque proved the viability of merging digital photogrammetric and 3D laser scanning data with "legacy data" (i.e., drawings and maps produced by earlier excavations and topographic surveys), to provide new hypotheses on the construction of the so-called Mausoleum Architectural Project, a constructive effort that involved the building of earlier phases of the Temple of Inscriptions and Temple XIII (Campiani et al, 2021).…”
