PS P (Chapter II, Evans Dissertation)

This is drone product set P from Chapter II of Alexandra's dissertation.<br>The orthomosaic and DSM show the Bellamy beaver dam area in Dover, NH, USA. The imagery was collected on November 22, 2019 using a DJI Phantom 3 Professional drone. Ground control points were used for georeferencing the imagery during SfM processing, surveyed with a Topcon Hiper Lite+. Automated drone flight paths were used to collect nadir and angled aerial images with sufficient image overlap for SfM processing in Agisoft PhotoScan Professional. The PhotoScan-generated report includes additional details on the SfM processing workflow and on the drone products.<br>Please see Alexandra's dissertation (University of New Hampshire) for more information on the drone products and project.<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.

本数据集为亚历山德拉（Alexandra）学位论文第二章中的无人机产品集P。正射镶嵌影像（orthomosaic）与数字表面模型（DSM）展示了美国新罕布什尔州多佛市的贝拉米海狸坝区域。该影像采集于2019年11月22日，使用大疆（DJI）Phantom 3 Professional无人机完成。地面控制点通过拓普康（Topcon）Hiper Lite+测量仪器采集，并在运动恢复结构（Structure from Motion，简称SfM）处理过程中用于影像的地理配准。本研究采用自动化无人机飞行航线采集天底与倾斜航空影像，影像重叠度满足使用Agisoft PhotoScan Professional软件开展SfM处理的要求。由该软件生成的报告包含了SfM处理流程与无人机产品的更多细节。
如需了解该无人机产品集与本项目的更多细节，请参阅亚历山德拉（Alexandra）于新罕布什尔大学（University of New Hampshire）提交的学位论文。
