Ítem Integrated and interactive 4D system for archaeological stratigraphy(Springer, 2022-09-27) Ortega-Alvarado, Lidia M.; García-Fernández, Ángel-Luis; Conde-Rodríguez, Francisco; Jurado-Rodríguez, Juan M.The digitization of some of the processes carried out in an archaeological excavation is changing the way of working at the site. Today, new technologies coexist with traditional methodologies. The study of stratigraphy can combine drawings of profiles and plans, the Harris Matrix diagram, as well as digitized files that perform a complete record of the stratigraphic sequence. However, this information is usually unaggregated from the rest of the information system that makes up the archaeological record. In this paper we present an integrated software tool and the associated methodology to record, store, visualize and analyze the 3D stratigraphy of a site. The implementation uses spatial databases to store information of a heterogeneous nature and game engines for the visualization and interaction with this information. During the excavation process, the strata are scanned using the Tof technology, which is available in many smartphones. The resulting 3D model of the stratum, once uploaded to the software system, allows us to visualize the sequence of strata incorporating the findings into their original arrangement. Some additional tools, such as the scrollbar, help to perform a temporal analysis of the site. The result is a 4D interactive stratigraphy tool, which together with the Harris Matrix, complements the archaeological record and facilitates the work to archaeologists. This methodology also allows to speed up the on-site work and the subsequent analysis, while improving the user experience with the 3D archaeological site replica.Ítem Integrated information system for 3D interactive reconstruction of an archaeological site(ACM, 2023-08-09) Calzado-Martínez, Alberto; García-Fernández, Ángel-Luis; Ortega-Alvarado, Lidia; Feito-Higueruela, Francisco-RamónArchaeological recording is intended to preserve as much information as possible about the finds. However, once the pieces are removed from the site, there is information regarding the original positioning of these pieces that may be lost or not accurately recorded, and can be relevant for further studies. This spatial arrangement can also be crucial for subsequent piece restoration or to understand certain aspects of ancient cultures. In this paper, we describe a software prototype and a methodology to virtually reconstruct an archaeological site for posterity, once it has been excavated. The system is implemented with a client-server architecture. In the server, a spatial database stores and manages the 3D models of the finds, as well as several 3D site ground surface models acquired at different times during the excavation process. On the client side, a graphical interface allows the user to manipulate the find models in order to recreate and virtually reconstruct the original spatial arrangement of the archaeological site. Topological relationships among the finds are stored in the database to provide further spatial analysis. The result is an integrated information system that goes beyond 3D visualization, making the site last for posterity after its excavation, and allowing further spatial analysis.
