| Description |
These data map in high detail surficial cross-sections of North Core Banks, a barrier island in Cape Lookout National Seashore, NC, in October 2022. U.S. Geological Survey field efforts are part of an interagency agreement with the National Park Service to monitor the recovery of the island from Hurricanes Florence (2018) and Dorian (2019). Three sites of outwash and overwash were targeted for extensive vegetation ground-truthing, sediment samples, bathymetric mapping with a remote-controlled surface vehicle, and uncrewed aerial systems (UAS) flights to collect multispectral imagery. Five permanent ground control points were also installed and surveyed to act as control for additional aerial imagery collects via plane. UAS imagery were processed in Agisoft Metashape (v. 1.8.1) to produce calibrated multispectral (red, blue, green, red-edge, near-infrared, and panchromatic) orthoimages and digital surface models.
