The Digital Archaeology Group has invited Sebastian Fajardo to discuss his research: "From Above - Revealing Pre-Hispanic Landscapes in the Mountainous Tropical Forests"
Abstract
Remote sensing has proven effective in identifying archaeological records concealed beneath forest canopies, particularly in regions without scarped landscapes and featuring large structures. However, the workflow and potential for conducting these surveys in scarped terrains with less conspicuous, yet technically and practically difficult ancient earthworks remains challenge that need to be addressed.
To address this gap, we are conducting a project that utilizes Light Detection and Ranging (LiDAR) technology in Colombia’s Sierra Nevada de Santa Marta. This initiative employs unmanned aerial vehicles (UAVs) and satellite remote sensing data to uncover irregular archaeological contexts within a region rich in pre-Columbian structures, including terraces, burials, retaining walls, paths, and staircases, all situated in a highly complex terrain. Our long-term goal is to enhance our understanding of the socio-technological complexities of pre-Columbian cultures in this area.
In this talk, we will present the preliminary results of our first field season and outline the next stages focused on data comparison and geometric feature extraction algorithms. We will also address the modern threats posed by agriculture, infrastructure development, and illegal logging to these archaeological sites, emphasizing the critical importance of identifying forest-covered areas to prevent the irreversible loss of cultural heritage. We aim to discuss ways to make these new technologies more accessible and affordable for all researchers and stakeholders. Our approach showcases the potential of LiDAR technology not only to advance archaeological research but also to support the initiatives of stakeholders and the four indigenous peoples of the region: the Arhuaco, Kankuamo, Kogui, and Wiwa.
