Photogrammetric modeling of archaeological sites and generation of cartographic products: support for research and dissemination of the cultural heritage of Serranópolis, Goiás, Brazil

Abstract

The use of geotechnologies in archaeological research offers several benefits, including more realistic representations of cultural assets, analytical tools, cartographic resources, and means for sharing data and disseminating results. However, it also presents challenges, such as the need for financial resources, training, integration with traditional methods, and standardization of procedures. With the aim of contributing to the development and dissemination of geotechnological applications in archaeology, this article presents the survey methods and products generated in the digital photogrammetric recording project of archaeological sites in Serranópolis, GO, proposed by IPHAN. This article describes the use of geotechnologies for processing spatial data and their applications in the digital recording and dissemination of 3D models. It emphasizes the advantages of using terrestrial photogrammetry in documenting archaeological sites for creating maps from 3D models and cartographic products. The SAM spectral classification for pigment segmentation, the extraction of metric information, and a method for disseminating the models are also presented. The article concludes that these technologies, especially terrestrial photogrammetry, have the potential in documentation, analysis, decision support, and dissemination of cultural heritage, thereby contributing to the democratization of access and preservation.
