Item type:Publication, Lasers Without Lost Cities: Using Drone Lidar to Capture Architectural Complexity at Kuelap, Amazonas, Peru(Taylor and Francis Ltd., 2020-02-20)We report the results of drone lidar survey at a high-elevation archaeological site in the Chachapoyas region of Peruvian Amazonia. Unlike traditional airborne remote sensing, drone lidar produces very high-density measurements at a wide range of scan angles by operating at low altitudes and slow flight speeds. These measurements can resolve near vertical surfaces and novel dimensions of variability in architectural datasets. We show in a case study at Kuelap that the number of detected structures almost exactly matches the number reported from previous ground level surveys, and we use these data to quantify the relative circularity and size frequency distribution of architectural structures. We demonstrate variability in domestic architecture that was obscured in previous models produced using low-resolution remote sensing. Spatial analysis of these attributes produces new hypotheses about the site’s construction history and social organization. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The effect of infrastructure investment on tourism demand: a synthetic control approach for the case of Kuelap, Peru(Springer Science+Business Media, 2022-12-01)In this paper we estimate the effect of infrastructure investment on tourism demand. For this purpose, we analyse the case of the Kuelap Archaeological Complex (Peru), which became more attractive and accessible following the construction of Peru’s first cable car system and the redevelopment of a nearby airport located in the city of Jaen. In order to estimate the effect of this infrastructure investment package on the number of visitors to Kuelap, we construct a synthetic control using characteristics from several archaeological sites in Peru similar to Kuelap. This synthetic control allows us to estimate the potential number of visits to Kuelap had the infrastructure investment package not been made. Thus, the causal effect is the difference between the actual visits to Kuelap and the ones to the synthetic control. The results show that the number of visits to Kuelap increased by approximately 100% in the wake of the infrastructure investment package.
