Geospatial Methods at Huaca del Loro


This is an abstract from the "Almost 100 Years since Julio C. Tello: Research at Huaca del Loro, Nasca, Peru" session, at the 88th annual meeting of the Society for American Archaeology.

Throughout the 2019 and 2022 field seasons, geospatial data were collected at Huaca del Loro using a combination of traditional and digital mapping techniques. Sand covers every corner of the site, so in 2019 a ground-penetrating radar was utilized to identify buried structures. This led to the discovery of a D-shaped temple that became the focus of the 2022 field season. Unit maps were drawn to scale and used in conjunction with a total data station, GIS, and Structure-from-Motion photogrammetry (SfM). SfM uses overlapping photos and ground control points to generate a scaled 3D representation of the photographed area, showing the exact spatial orientation of features, structures, and units. In addition to these methods, photos were collected using a drone to generate a high-resolution aerial base map, and sketch maps created by previous researchers were digitized and georeferenced in order to better understand the context of data that was gathered during previous excavations.
