Abstract

At present there is no systematic record of the size, form or density of architecture at Hawaiian royal centres. We report on the results of a UAV LiDAR survey of one of the best-preserved examples of a royal centre in the archipelago: Hōlualoa Royal Centre, Kona District, Hawai‘i Island. The resolution of our data (0.3–0.1 m) is far superior to previous airborne LiDAR surveys (1.0 m); however, several factors, including thick understory vegetation, made resolving archaeological targets challenging. We nonetheless were able measure the volume of building material of the largest features, which allows us to compare structures in this royal centre with other monuments in the region. This study highlights the advantages, and limitations, of UAV LiDAR as well as the need for more high-quality quantitative data on architecture at royal centres.

利用无人机获取的激光雷达绘制古建筑:以夏威夷岛科纳区Hōlualoa皇家中心为例
目前还没有关于夏威夷皇家中心建筑的大小、形式或密度的系统记录。我们报告了无人机激光雷达对群岛中保存最完好的皇家中心之一的调查结果:Hōlualoa皇家中心,科纳区,夏威夷岛。我们的数据分辨率(0.3-0.1 m)远远优于以前的机载激光雷达调查(1.0 m);然而,包括茂密的林下植被在内的几个因素使得解决考古目标具有挑战性。尽管如此,我们还是能够测量出最大特征的建筑材料的体积,这使我们能够将这个皇家中心的结构与该地区其他纪念碑的结构进行比较。这项研究强调了无人机激光雷达的优点和局限性,以及对皇家中心建筑更多高质量定量数据的需求。
