ABSTRACT 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.

没有失落之城的激光器：使用无人机激光雷达捕捉秘鲁亚马逊亚马逊库拉普的建筑复杂性

摘要我们报告了秘鲁亚马逊河Chachapoyas地区一个高海拔考古现场的无人机激光雷达调查结果。与传统的机载遥感不同，无人机激光雷达通过在低海拔和缓慢的飞行速度下运行，可以在很大的扫描角度范围内进行非常高密度的测量。这些测量可以解析出接近垂直的表面以及建筑数据集中新的可变性维度。我们在Kuelap的一个案例研究中显示，检测到的结构数量几乎与以前的地面勘测报告的数量完全匹配，并且我们使用这些数据来量化建筑结构的相对圆度和尺寸频率分布。我们展示了使用低分辨率遥感技术制作的先前模型所掩盖的家庭建筑可变性。
