UAV-based modeling to see the non-visible: A methodological reflection in Pachacamac

摘要

This paper offers a first methodological look at representing the non-visible in a large scale archaeological site, Pachacamac (Peru). Digitization based on aerial photo-grammetry and ground-penetrating radar (GPR) using an unmanned aerial vehicle (UAV) results in a large volume of data. This data is often used to record the state of a site at the moment of the capture (photogrammetry) or for archaeological prospective (GPR). Our approach proposes to extend the use of such types of big data to gain better knowledge about the logic of urban planning in the context of a heritage study.
