The Use of 3D Photogrammetry in the Analysis, Visualization, and Dissemination of the Indigenous Archaeological Heritage of the Greater Antilles

Abstract

Abstract The development of digital technologies and the use of advanced photogrammetry programs for modeling archaeological excavations and sites have opened new possibilities for spatial analysis in archaeology and the reconstruction of archaeological contexts. In addition, these tools allow us to visually preserve the features of archaeological sites for future use and facilitate the dissemination of archaeological heritage to local communities and the general public. This paper summarizes 3D photographic visualization of three cave art sites (Los Cayucos and Cueva No. 1 in Punta del Este, Cuba, and José María Cave in the Dominican Republic) and two burial spaces (Canímar Abajo and Playa del Mango, Cuba) using photogrammetry software. The application of these novel methods at the cave art sites allowed us to visualize faint pictographs that were invisible to the naked eye, to better define the shapes of petroglyphs and to reconstruct the position of lost/removed panels. At the burial sites, 3D modeling allowed us to register the archaeological context with greater precision. The use of 3D modeling will improve spatial analysis and data safeguarding in Cuban archaeology. Moreover, 3D movies are an effective way to disseminate knowledge and connect local communities with their cultural heritage, while reducing the impact of public visits to remote or endangered sites.
