Three-dimensional modeling of the La Pastora Dolmen in Valencina de la Concepción, Seville, using photogrammetric techniques

Abstract

In this study, we present the advances of photogrammetry applied to prehistorical research, focusing on the creation of three-dimensional models of the dolmens of Valencina de la Concepción (Seville). Photogrammetry has proven to be an invaluable tool in the documentation and analysis of archaeological sites, enabling precise and detailed capture of ancient architecture. In this study, we applied photogrammetric techniques to capture high-resolution images of Dolmen de La Pastora, one of the most significant megalithic monuments of the 5th millennium BP in the Iberian Peninsula with great historical and cultural importance.

This multidisciplinary focus allows us not only to visually explore the monuments in detail but also to analyse their internal structure, orientation, and possible construction patterns. Additionally, we explore the utility of these 3D models in archaeological education and outreach, offering researchers and the general public the opportunity to virtually interact with these historical monuments.

In conclusion, this work manifests the possibilities the power of photogrammetry offers in the field of prehistorical research and its ability to revolutionize the way we study and understand our past. The generated 3D models not only enhance our appreciation of megalithic architecture but also provide an innovative approach to the analysis and preservation of endangered or deteriorating archaeological sites. With this contribution, apart from, we aim to advance the exploration of prehistory and inspire future interdisciplinary research in the fields of archaeology and image technology, providing possible visits to places that are difficult to access or where the constant passage of humans may cause deterioration to the World Heritage Sites.
