As lidar becomes a regular part of surveying, ground-based platforms (handheld, mobile, and terrestrial lidar) and airborne platforms (piloted aircraft) are being joined by unpiloted aerial vehicle (UAV)–acquired lidar. We present a method for leveraging UAV-acquired lidar data with data collected using different lidar platforms (terrestrial and piloted aircraft), at a range of resolutions (1 to +1,000 points per m2) and geographic scales. We use these instruments to document a dry-masonry stone wall enclosing a religious precinct within the royal center at Kealakekua, Kona District, Hawai'i Island. Prior to European contact in AD 1779, Kealakekua was the center of the island-wide polity during the annual Makahiki festival. Results of this study suggest that when the wall was constructed around AD 1640, it was the largest structure ever built on the island of Hawai'i as well as a strong material expression of the power of state religion and the Makahiki rituals.

无人驾驶飞行器获得了用于绘制纪念性建筑的激光雷达

随着激光雷达成为测量的常规部分，地面平台（手持式、移动式和地面激光雷达）和机载平台（有人驾驶飞机）正在加入无人驾驶飞行器 (UAV) 获取的激光雷达。我们提出了一种利用无人机获取的激光雷达数据和使用不同激光雷达平台（地面和有人驾驶飞机）收集的数据的方法，分辨率范围为每米 1 到 +1,000 点2) 和地理尺度。我们使用这些工具记录了夏威夷岛科纳区 Kealakekua 皇家中心内的宗教区的干砌石墙。在公元 1779 年与欧洲接触之前，Kealakekua 在一年一度的 Makahiki 节期间是全岛政体的中心。这项研究的结果表明，当围墙在公元 1640 年左右建造时，它是夏威夷岛上有史以来最大的建筑，也是国家宗教和 Makahiki 仪式力量的强烈物质表达。
