随着激光雷达成为测量的常规组成部分，地面平台（手持式、移动的和地面激光雷达）和机载平台（有人驾驶飞机）也加入了无人驾驶飞行器（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的方法，这些数据是使用不同的激光雷达平台（地面和有人驾驶的飞机）收集的，分辨率范围为（每平方米1到+1，000个点）和地理尺度。我们用这些仪器记录了夏威夷岛科纳区凯阿拉凯夸的皇家中心内一堵封闭宗教区的干砌石墙。在公元1779年与欧洲人接触之前，Kealakekua是每年Makahiki节期间全岛政治的中心。这项研究的结果表明，当这堵墙建于公元1640年左右时，它是夏威夷岛上有史以来最大的建筑，也是国家宗教和Makahiki仪式力量的有力物质表达。
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.
