DUNEX was a collaborative community-led experiment that took place in the fall of 2021 along the Outer Banks of NC, with the goal of improving the understanding, observational techniques, and predictive capabilities for extreme storm processes and impacts within the coastal environment. At the USFWS PINWR site, cameras were deployed for about a month, from September 18 to October 24, 2021, during which several storms passed offshore of the site. The cameras were mounted on separate 7-meter (m) tall masts within the dune, facing northeast and offshore, in a stereo configuration with approximately 75% overlap in field of view, to measure shoreline water levels and coincident topographic beach profiles. Images were collected during daylight hours with two schemes: 1) both cameras recording at 1 Hertz (Hz) for 5 minutes (min) starting 10 min before the hour for stereo photogrammetric processing to measure topographic beach profiles, and 2) one camera recording at 2 Hz for 17 min starting at the top of the hour for producing snapshots and time-averaged image products used to measure wave runup. This metadata record is for camera 2 and includes the necessary intrinsic orientation (IO) and extrinsic orientation (EO) calibration data to utilize the imagery to make quantitative measurements. The cameras are part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. USGS researchers utilize the imagery collected from these cameras to remotely sense a range of information including shoreline position, sandbar migration, wave runup on the beach, alongshore currents, and nearshore bathymetry. This camera is part of the USGS CoastCam network. To learn more about the DUNEX camera deployment visit https://www.usgs.gov/centers/whcmsc/science/dunex-pea-island-experiment. Purpose: These data can be utilized to produce orthorectified products that can be viewed in a geographic information system (GIS) or other software to identify topographic and shallow-water bathymetric features. See the image processing toolbox developed by Bruder and Brodie (2020) for more information. To ensure that USGS-St. Petersburg data management protocols were followed, a USGS field activity number (FAN) was assigned for this survey; 2021-340-FA. Additional information about this FAN is available on the Coastal and Marine Geoscience Data System (CMGDS): https://cmgds.marine.usgs.gov/fan_info.php?fan=2021-340-FA. Supplemental_Information: The bounding coordinates below represent the limits of the rectified images from the CoastCam that covers the entirety of the beach at low tide and approximately 300 m directly in line of the camera facing alongshore. The intrinsic calibration photos were taken on 20210914 and their location information is not consequential.

Calibration success can be examined using the CIRN Quantitative Coastal Imaging Toolbox (Bruder and Brodie, 2020) where parameters azimuth, tilt, and roll have errors less than 2 degrees. Accuracy of the extrinsic calibration was also tied to human ability to locate targets in the imagery. The camera systems were liable to move over time via wind, wear, and human interactions cleaning the camera - all of which may change the camera calibration parameters. Calibration data is stored in YML files named with the calibration date. Logical_Consistency_Report: The camera system installed (FLIR BFLY-PGE-12055C-C) had an extrinsic and intrinsic calibration process. The EO process was completed on 20210918 and 20211006 and for each date consists of a YML file of resultant EO parameters, a comma-separated values (CSV) file of GCP locations and description, and two JPEG images, one labeled as 'raw' and the other as 'annotated', showing the GCP targets that were surveyed. The IO calibration was completed on 20210914 and consists of 19 JPEG images of a checkerboard pattern that collectively covered the entire image frame, used with the Camera Calibration Toolbox (Bouguet, 2022) to solve for the intrinsic parameters and lens distortion, which are provided in a YML file of resultant IO parameters. These are used in the CIRN toolbox steps A through C to be able to georectify imagery and make quantifiable measurements. Completeness_Report: All calibration images and surveyed GCPs are provided even if not all are necessary for calibrating the camera. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Real-Time Kinematic (RTK) Global Positioning System (GPS) equipment with decimeter horizontal accuracy was used to survey ground control points (GCPs) within the camera field of view (Over and others, 2022) and used to validate the extrinsic camera calibration. The precise locations of the targets are used in the CIRN Quantitative Coastal Imaging Toolbox steps B and C (Bruder and Brodie, 2020). Horizontal coordinates are referenced to the North American Datum of 1983 (National Spatial Reference System 2011) Universal Transverse Mercator Zone 18 North (NAD83(2011)/UTM Zone 18N) coordinate system. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: RTK GPS equipment was used to survey GCPs within the camera field of view (Over and others, 2022) and used to validate the extrinsic camera calibration. The precise locations of the targets are used in the CIRN Quantitative Coastal Imaging Toolbox steps B and C (Bruder and Brodie, 2020). Vertical positions are referenced to the North American Vertical Datum of 1988 (NAVD88) coordinate system. Lineage: Process_Step: Process_Description: The CoastCam (camera 2) was used to take IO photos. This involved laying a printed checkerboard with 2.7-centimeter (cm) squares flat and keeping it stationary, then moving the camera to take images of the checkerboard in various parts of the cameras field of view. An example image can be found in dunex_c2_calibrationIOEO_exampleImagery.zip. There are a total of 19 IO images (dunex_c2_20210914_IO.zip) used for the intrinsic calibration (Bouguet, 2022). These were used in step A in the Camera Calibration procedures outlined in Bruder and Brodie (2020). The resultant parameters are stored in a YML file located in dunex_c2_20210914_IO.zip. Image file naming format follows dunex_c2_20210914_IO_## , where dunex is the site name, c2 is the camera name, 20210914 is the date the images were taken (YYYYMMDD format), IO is Intrinsic Orientation, and ## is the image number out of 19 used in the IO calibration process.

GCPs were collected on 20210918 and 20211006. To place the photos taken by the CoastCam into real world coordinates and to rectify them into a planar view, objects within the field of view of the camera must be located. To do so, the elevation and position of the camera lenses in the CoastCam setup were measured with the RTK GPS. Then, multiple stationary targets were spread through the camera field-of-view to be used as GCPs, and the location of each was measured with the RTK GPS equipment. The GCPs consisted of large square targets, divided into quadrants and colored white and black, and were either made of fabric and laid flat on the ground (center point on ground was surveyed) or made of wood and propped up to face the CoastCam (bottom-center, between black and white at ground level, was surveyed). When all GCPs were in place, a snapshot was taken with the camera on two separate survey dates (dunex_c2_20210918_GCP_image_raw.jpg and dunex_c2_20211006_GCP_image_raw.jpg). The survey locations of the GCPs in the CSV files were used to hand label the raw images to generate annotated images (dunex_c2_20210918_GCP_image_annotated.jpg and dunex_c2_20211006_GCP_image_annotated.jpg) so that the targets could be labeled correctly in Step B of the Camera Calibration steps in Bruder and Brodie (2020). The pixel coordinates of each GCP within the raw images (hand-selected), solved in Step B of Bruder and Brodie (2020), the GPS positions from the CSV files, and the IO parameters in the IO YML file were used in Step C of the Camera Calibration steps in Bruder and Brodie (2020) to solve for the EO parameters. The resultant parameters for the EO calibration are stored in YML files located in dunex_c2_20210918_EO.zip and dunex_c2_20211006_EO.zip .

The elevation and position of the lenses in the CoastCam setup were estimated by surveying the legs of the camera tower with RTK GPS, and computing the mean horizontal position and mean elevation, and adding the tower height. The CoastCam took pictures of the position of each target within the camera view. The '_EO' zip folders each contain the GCP CSV file, the resultant EO parameters in a YML file, and 'raw' and 'annotated' images showing all the GCPs. The CSV files (dunex_c2_20210918_EO_GCPsurvey.csv and dunex_c2_20211006_EO_GCPsurvey.csv) with all the measurements were populated and GCP numbers were hand labeled on the annotated images (dunex_c2_20210918_GCP_image_annotated.jpg and dunex_c2_20211006_GCP_image_annotated.jpg) so that the targets could be labeled correctly in Step B of the Camera Calibration steps in Bruder and Brodie (2020). There are a total of 4 JPEGs. Images have EXIF and other imagery header information encoded within each file, see the process steps for more information.
