This is related to the field activity 2024-016-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region that falls within the field of view of two video cameras aimed at the beach (CoastCam CACO-02). In March and April 2024, U.S. Geological Survey and Woods Hole Oceanographic Institution (WHOI) scientists conducted field surveys to collect topographic and bathymetric data. A camera (Ricoh GRII) attached to a helium filled balloon-kite (Helikite) took images of the beach for use in structure-from-motion. High-precision GPS targets (AeroPoints V2) were used as ground control points. Bathymetry was collected in the nearshore using a single-beam echosounder mounted on a surf capable self-righting electric autonomous surface vehicle. Agisoft Metashape (v. 2.1.0) was used to create a digital surface model and orthomosaic with the collected imagery. These RGB 3-band images were collected of the waterline, beach, and bluffs with sufficient overlap to produce structure-from-motion photogrammetry products. Each image has position information to speed up alignment in the photogrammetry processing.

Marsjanik 2021 raster and tabular data data release DOI:10.5066/P9POZ9VH Reston, VA U.S. Geological Survey This publication is the survey data of Marconi Beach from 2021. https://doi.org/10.5066/P9POZ9VH The camera (Rioch GRII) used on the Helikite acquired files generally between 5 and 6 MB on disc, depending on image complexity. Some images were blurry due to movement and changing low light conditions. The Helikite was let up at a target altitude of 20-40 m above surface level to map the Marconi Beach shoreline and bluff face in Wellfleet, MA, on March 22, 2024. Photographs were captured every 2 for the first half and after checking the overlap, changed to 5 seconds for the remainder of the survey. A total of 1,637 images were collected, but only 1,113 are provided; images taken while the Helikite was launched, stationary, and put away were removed. All photos included have location information. Though the images do not represent spatial data, the spatial information is embedded in the photo and available in the EXIF header of each image, which is also provided in 2024-016-FA_Marconi_photoLocations.csv. The location information was estimated from the Agisoft Metashape project, which was georeferenced with the ground control point (GCP) AeroPoint V2 targets. The overall estimated horizontal accuracy of the project based on GCPs is 1 cm. Though the images do not represent spatial data, the spatial information is embedded in the photo and available in the EXIF header of each image, which is also provided in 2024-016-FA_Marconi_photoLocations.csv in the larger work citation. The location information was estimated from the Agisoft Metashape project, which was georeferenced with the AeroPoint V2 targets. The overall estimated vertical accuracy of the project based on GCPs is 2 cm. These JPEG images were collected with a camera (Ricoh GRII) hung from the Helikite on a GoPro mount so that the camera faced downward and towards the bluff at a roughly 45-degree angle. The Helikite was on a 60 m string and kitesurfing harness; together, the Helikite and gear were walked up and down the beach to achieve overlapping images. It is recommended when using the imagery for photogrammetric purposes to also use the ground control point locations (see 2024-016-FA_Marconi_nav_GCPs.csv). 202404 Peter Traykovski Woods Hole Oceanographic Institution Associate Scientist mailing and physical address

Woods Hole MA 02543 508-289-2638 ptraykovski@whoi.edu The images acquired with the camera were geotagged and processed to add additional information required by the USGS to the EXIF headers using ExifTools (https://exiftool.org/, version: 12.06), and the files were renamed to a unique identifier using Namexif (http://www.digicamsoft.com/softnamexif.html, version 2.1) to avoid any possibility of duplicate names. These steps are described here. For more information on the EXIF tags here and automatically populated by the camera see https://exiftool.org/TagNames/EXIF.html 1. The positions and elevations of each image (2024-016-FA_Marconi_photoLocations.csv) are from the estimated locations in the Metashape project using the images and AeroPoint V2s (see larger work citation). These positions are copied out of the project after alignment and refinement (see structure from motion metadata in the larger work citation). ExifTools was used to tag each photo with the following tags: Credit, Copyright, UsageTerms, ImageDescription, Artist, GPSAreaInfo, GPSMapDatum, GPSLatitude, GPSLongitude, and GPSAltitude stored in a CSV file with the command:' -exiftool -csv="C:\directory\name\Geotags_EXIF.csv" C:\directory\name\of\photos *.JPG To read out the photo information to a CSV when in the directory with the photos the command is: exiftool -csv *.JPG > directory/name/allheaders_out.csv 2. All the JPEG images were renamed with Namexif (https://us.digicamsoft.com/softnamexif.html v 2.2 accessed April 2020) to ensure unique filenames and compliance with the USGS Coastal and Marine Hazards and Resources Program's best practices for image naming convention. Images were renamed with the field survey ID prefix; flight number, and ID that distinguishes USGS cameras by make/camera number, the image acquisition date, coordinated universal time (UTC) in ISO8601 format, and a suffix with the original image name. For example, image name '2024016FA_f01r02_20240322T165822Z_image####.jpg', 2024016FA is the survey ID, f01 is the flight number, r02 is the camera make (Ricoh) and ID (02), and 20240322 is the UTC date in the format YYYYMMDD. A 'T' is used to separate UTC date from UTC time in format HHMMSS followed by a Z, and image####.jpg is the original raw photo name appended to the end of the new filename. 202404 Jin-Si R.
