Summary
[edit]DescriptionUpper Sawyer Mill Dam site aerial, 2020-06-03.jpg |
English: Description from source:
"A set of aerial photos of the Sawyer Mill upper dam removal project in Dover, NH. The photos span August 2017 through August 2020. The photos were taken using a DJI Phantom 3 Professional small unmanned aerial system from a variety of altitudes, and the photos were touched up in Adobe Lightroom. Evans, a FAA Part 107 certified remote pilot, collected the photographs. These photos are a subset of photos collected for long-term dam removal monitoring efforts that are part of the Future of Dams project. These images 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. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation." |
