Establishment of the state of conservation in archaeological sites by uavs study case: Cerro catequilla

Abstract:

Drones combined with proper aerial photogrammetry techniques reconstruct quickly and accurately the three-dimensional surface of an archeological site. The Cerro Catequilla is part of the national archaeological heritage in Ecuador, whose importance lies in the fact that it is crossed by the equator. However, this unique site has a clear deterioration. The objective was to demonstrate and establish the conservation status, using drones, as an optimal and effective alternative applied to archaeological sites. Through a geodesic survey, photogrammetric support points were placed for the processing of images captured with a Phantom 4 drone. With the photogrammetric products generated, very precise morphological and geometric characteristics of the ruins and recent anthropic damage such as excavations, abandoned buildings and 60% of the destroyed ruins were determined. In addition, thanks to the use of the drone it was possible to preserve and digitally record the history of the site with a high degree of detail.
