Drone Photographs from the Middle Impoundment 2019-7-19 Flight Date (Dover, NH, USA)

These are the raw drone aerial images taken of the middle impoundment area on July 19, 2019 for the Evans et al. Sawyer Mill dam removal study. Alexandra Evans, a certified FAA Part 107 remote pilot, served as the remote pilot in command for the flight mission and was accompanied by a spotter.<br>A DJI Phantom 3 Professional drone was used to take the images, equipped with its original RGB camera and a polarizing filter. Please see the referenced automated flight paths for details on altitude, image overlap, etc. The flight paths were executed using the Litchi flight app.<br>These materials were made using resources from an NSF EPSCoR funded project “RII Track-2 FEC: Strengthening the scientific basis for decision-making about dams: Multi-scale, coupled-systems research on ecological, social, and economic trade-offs” (a.k.a. "Future of Dams"). Support for this project is provided by the National Science Foundation’s Research Infrastructure Improvement NSF #IIA-1539071.

本数据集包含2019年7月19日为埃文斯（Evans）等人开展的索耶米尔（Sawyer Mill）大坝拆除研究拍摄的中部库区原始无人机航拍影像。本次飞行任务的遥控机长为持有美国联邦航空管理局（FAA）第107部遥控飞行员资质的亚历山德拉·埃文斯（Alexandra Evans），飞行期间配有一名观察员协助警戒。

本次影像采集使用大疆（DJI）精灵3专业版（Phantom 3 Professional）无人机，搭载原厂RGB相机与偏振滤镜。关于飞行高度、影像重叠率等具体参数，请参阅参考资料中的自动化飞行航线说明。本次飞行航线通过Litchi飞行应用程序规划执行。
