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, overwash, and pond formation 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 semi-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) with surveyed temporary ground control points to produce calibrated multispectral (red, blue, green, red edge, near infrared, and panchromatic) orthoimages and digital surface models. Purpose: Photos of the beach surface were taken next to a quarter for scale. The images were uploaded to the Sandsnap database to estimate grain size with a deep learning neural network (https://sandsnap-erdcchl.hub.arcgis.com). These grain-size data may be used in numerical models of coastal dynamics and to better understand how the channels and ponds formed during Hurricane Dorian fill in.

Browse_Graphic_File_Type: JPEG Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Photos were taken according to the SandSnap instructions, and grain-size accuracy was estimated with a trained model detailed on the website (https://sandsnap-erdcchl.hub.arcgis.com). Images that were improperly taken that have shadows, an unsmooth surface, are blurry, or from too far a distance may not be as accurate or may fail to return results. There is no way to validate the SandSnap grain-size estimate without sediment samples. Logical_Consistency_Report: There are 96 images and 18 have sediment samples associated with them. The SandSnap IDs are not consecutive due to errors uploading to SandSnap. Completeness_Report: All images were uploaded to SandSnap but not all images returned a result. No-data is represented using NaN. Additional information not in the CSV (for example: Town, Coin Reference, and Model Training Date) are generated by SandSnap. These data are available on the site and can be found by searching the SandSnap ID of each sample. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal positions for the images are determined by smartphone GPS and are imbedded in the image. The expected absolute, horizontal accuracy is 2 to 5 meters, although some images may have larger inaccuracies due to poor cell service. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical positions for the images are determined by smartphone GPS and are embedded in the image. The expected absolute, vertical accuracy is 5 to 10 meters, although some images may have larger inaccuracies due to poor cell service Lineage: Process_Step: Process_Description: A smartphone picture was taken of the surface with a quarter for scale to use with SandSnap.
