[2019-8-22] Vegetation Area Drone Orthomosaic, Digital Surface Model, and Processing Report

This is the drone orthomosaic, digital surface model (DSM), and PhotoScan-generated report for the August 22, 2019 sampling date for the Evans et al. Sawyer Mill dam removal study. This data is for the vegetation study area on the Bellamy River in Dover, NH, USA. A DJI Phantom 3 Professional small unmanned aerial system was used to collect the aerial imagery. The imagery was processed in Agisoft PhotoScan Professional. A Topcon Hiper Lite+ was used to collect the survey data. The products' XY is in WGS 84, and the vertical datum corresponds to NAVD88 in meters. Please see the Evans et al. Sawyer Mill dam removal reservoir response manuscript for additional information on the products. This product set was also used in Alexandra's dissertation (University of New Hampshire, 2021).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.
