尽管航空激光雷达已被证明是绘制考古景观的强大工具，特别是在世界森林地区，但从飞机或专业级无人机购买传统激光雷达的高昂成本仍然是许多研究人员面临的一个障碍。最近开发的超紧凑型、相对低成本的激光雷达测绘系统可以部署在消费级无人机上，现在考古学家可以收集自己的高分辨率航空激光雷达遗址和景观，但这些系统的有效性在很大程度上仍未得到测试。本文介绍了使用超紧凑型无人机部署的激光雷达在三个不同环境中的考古遗址进行的调查结果：1)夏威夷凯拉凯库亚湾国家历史公园的热带森林；2)科罗拉多州梅萨维德北角的皮尼翁-杜松林；3)新汉普郡恩菲尔德·沙克村的落叶-常绿混交林。研究结果揭示了三个研究地点的丰富考古特征，表明了无人机激光雷达作为考古勘探工具的潜力，但也说明了利用这一令人兴奋的新兴技术所涉及的一些重大技术和实践挑战。
Although aerial lidar has proven to be a powerful tool for mapping archaeological landscapes, particularly in forested regions of the world, the high costs of conventional lidar acquisition from aircraft or professional-grade drones remains a hurdle to many researchers. The recent development of ultra-compact, relatively low-cost lidar mapping systems that can be deployed on consumer-grade drones now make it feasible for archaeologists to collect their own high-resolution aerial lidar of sites and landscapes, but the efficacy of these systems remains largely untested. This paper presents results of surveys undertaken using a ultra-compact, drone-deployed lidar at archaeological sites located in three different environments: 1) tropical forests at Kealakekua Bay State Historic Park, Hawai’i, 2) piñon-juniper forest on Mesa Verde’s North Escarpment, Colorado, and 3) mixed deciduous-evergreen forest at Enfield Shaker Village, New Hampshire. Results reveal a wealth of archaeological features at the three study sites and demonstrate the potential of drone-based lidar as a tool in archaeological prospection, but also illustrate some of the significant technical and practical challenges involved in making use of this exciting emerging technology.
