无人机（UAV）越来越多地用于许多科学应用，包括考古调查。我们测试的适用性和实用性的无人机测量在巴西的热带低地和技术可视化产生的数字高程模型，特别是红色浮雕图像地图（RRIM）。我们提出了无人机调查的结果，在四个不同的考古遗址位于亚马逊河流域西南部，在英亩的状态。从无人机导出的点云生成的高程模型显示了场地布局中的清晰模式，并揭示了在地面上不易辨别的微妙的场地内地形特征。我们的研究表明，无人机具有成本效益，并提供非常详细的地形测绘和可视化的考古特征时，植被覆盖率足够低，稀疏的结果。与传统的测绘方法相比，无人机数据采集的快速数据捕获和空间采样偏差的缺乏是一个显着的优势。此外，无人机测量和无人机衍生数据处理不需要昂贵的技术或专业的用户专业知识，因为开源软件和易于使用的工具包随时可用。
Unmanned aerial vehicles (UAVs) are increasingly used for many scientific applications, including archaeological surveys. We test the suitability and practicability of UAV surveying in the tropical lowlands of Brazil and techniques for visualizing the resulting digital elevation models, specifically the Red Relief Image Map (RRIM). We present the results of UAV surveys conducted at four diverse archaeological earthwork sites situated in interfluvial southwestern Amazonia, in the state of Acre. The elevation models produced from UAV derived point clouds display clear patterns in the site layouts and reveal subtle intra‐site earthwork features that are not easily discernible on the ground. Our study demonstrates that UAVs are cost efficient and give highly detailed results for topographic mapping and visualization of archaeological features when vegetation cover is sufficiently low and sparse. The rapid data capture and lack of spatial sampling bias of the UAV data collection is a significant advantage compared to conventional mapping methods. Furthermore, UAV surveying and UAV derived data processing do not require expensive technologies or specialized user expertise, since open‐source software and easy‐to‐use toolkits are readily available.
