Recent substantial technological progress has been made in the manufacturing and availability of unmanned aerial systems (UAS, also known as UAV or drones) and the lightweight active and passive sensing devices that can be integrated into their platform as payloads. The development of these integrated systems is driving an emergent field of aerial applications in field-based research. Researchers can now capture location-embedded visible light aerial photographs with ease as well as remote sensing data at spectral, spatial, and temporal resolutions not achievable from terrestrial or satellite-based systems. In anticipation of the growth in aerial based research, this IRES project will provide training and resources for 12 U.S. undergraduate students to learn and operate UAS, become familiar with national UAS regulations and protocols, design and implement aerial surveys, process aerial data using photogrammetric and GIS software, and create products that integrate aerial and terrestrial datasets in a meaningful and informative way. This IRES project centers on the geoarchaeology of ancient marble producing quarries in Greece that span from the Bronze Age through Early Byzantine period and will be conducted under the auspices of the Wiener Laboratory for Archaeological Science at the American School of Classical Studies at Athens. Over the past few decades, geoarchaeologists, physicists, and chemists have developed a geochemical and stable isotope database to differentiate between the major marble producing quarries utilized in antiquity. The database is used to assess provenance of marble artifacts including statuary, architecture, and furniture. However, very little effort has been given to the survey and recording of the physical quarries themselves. A thorough aerial and terrestrial survey of ancient marble quarry fields will provide improved assessment of the size and extent of quarry fields, dimensions of individual quarry pits, and the possibility of identifying previously unknown pits. Building from a review of maps and archaeology reports, IRES participants will design and implement data collecting missions with UAS platforms equipped with visual light cameras as well as multispectral and LiDAR sensors. IRES participants will gain the skills necessary to process the data with photogrammetric and GIS software to develop accurate high-resolution three-dimensional point clouds. Participants will use the point clouds to render accurate georectified digital terrain models that include quarry boundaries, tailing piles, and slipways. Interpreted surface features will be verified by groundtruthing. Participants will use the aerial and terrestrial imagery to generate accurate three-dimensional models of the quarry pits, allowing for the determination of quarry volumes and the calculation of the amount of extracted marble. IRES participants will integrate published geochemical and stable isotope datasets to each quarry model, and develop kmz-based online resource for geologists, geomorphologists, archaeologists, and others interested in ancient Greek marble resources.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

最近，无人机系统（UAS，也称为UAV或无人机）的制造和可用性以及可作为有效载荷集成到其平台中的轻型主动和被动传感设备方面取得了重大技术进步。这些集成系统的发展正在推动一个新兴的基于实地研究的航空应用领域。研究人员现在可以轻松地捕获位置嵌入的可见光航空照片，以及光谱、空间和时间分辨率的遥感数据，这是地面或卫星系统无法实现的。考虑到航空研究的增长，这个IRES项目将为12名美国本科生提供培训和资源，以学习和操作无人机，熟悉国家无人机法规和协议，设计和实施航空调查，使用摄影测量和GIS软件处理航空数据，并以有意义和信息丰富的方式创建集成空中和地面数据集的产品。这个IRES项目的中心是希腊从青铜器时代到早期拜占庭时期的古代大理石采石场的地质考古学，将在雅典美国古典研究学院的维纳考古科学实验室的主持下进行。在过去的几十年里，地质考古学家、物理学家和化学家开发了一个地球化学和稳定同位素数据库，以区分古代使用的主要大理石采石场。该数据库用于评估大理石文物的来源，包括雕像、建筑和家具。然而，很少有人对采石场本身进行调查和记录。对古代大理石采石场进行彻底的空中和地面调查，将提供对采石场的大小和范围、单个采石场的尺寸以及识别以前未知坑的可能性的改进评估。根据对地图和考古报告的审查，IRES参与者将设计和实施配备可见光相机以及多光谱和激光雷达传感器的无人机平台的数据收集任务。IRES参与者将获得使用摄影测量和GIS软件处理数据的必要技能，以开发精确的高分辨率三维点云。参与者将使用点云绘制精确的地理校正数字地形模型，包括采石场边界、尾矿堆和船台。解释后的地表特征将通过地面测实加以验证。参与者将使用空中和地面图像生成采石场的精确三维模型，从而确定采石场的体积和计算提取的大理石数量。IRES参与者将把已发布的地球化学和稳定同位素数据集整合到每个采石场模型中，并为地质学家、地貌学家、考古学家和其他对古希腊大理石资源感兴趣的人开发基于kmz的在线资源。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
