Every hour during daylight hours, daily from February 1, 2019, to July 15, 2019, the camera collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and extrinsic orientation (EO) calibration data to utilize imagery to make quantitative measurements. The camera is part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. USGS researchers analyzed the imagery collected from this camera to remotely sense a range of information including shoreline position, sandbar migration, wave run-up on the beach, alongshore currents, and nearshore bathymetry. This camera is part of the USGS CoastCam network (https://www.usgs.gov/coastcams), supported by the Total Water Level/Coastal Change Project under the Coastal and Marine Hazards and Resources Program (CMHRP). To learn more about this specific camera visit https://www.usgs.gov/centers/pcmsc/science/using-video-imagery-study-wave-dynamics-isla-verde. Purpose: These data can be processed 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 data management protocols were followed, each survey was assigned a USGS field activity number (FAN); 2018-670-FA. Additional information about the field activities from which the extrinsic orientation (EO) calibration data were derived are available on the Coastal and Marine Geoscience Data System (CMGDS): https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-670-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 meters (m) directly in line of the camera facing alongshore. The intrinsic calibration photos were taken at the deployed location on 20181105 (YYYYMMDD) and their location information is not consequential.

Calibration success can be examined using the CIRN 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. The latest parameters are stored in the YAML files named with the date first active. Logical_Consistency_Report: The camera system installed (FLIR BFLY-PGE-50S5C-C) had an intrinsic and extrinsic calibration process. The EO process was completed on 20181106 and consists of a YAML 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'. The intrinsic orientation (IO) calibration consists of a total of 58 images and the extrinsic calibration uses one “timex” photo with GCP targets that have pre-established location information. Of the 58 photos, 55 images that collectively covered the entire image frame were selected to solve for the intrinsic calibration. The 3 images excluded were: IslaVerdePR_c1_20181105_021.jpg, IslaVerdePR_c1_20181105_112.jpg and IslaVerdePR_c1_20181105_164.jpg. These are used in the CIRN Toolbox steps A through C. Results of the intrinsic and extrinsic calibrations are stored in separate YAML files (IslaVerdePR_c1_20181105_IO.yaml, IslaVerdePR_c1_20181106_EO.yaml). Completeness_Report: All calibration images are provided even if not all images are necessary for calibrating the camera. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: PPK equipment collected in field activity 2018-670-FA were used to validate the extrinsic camera calibration using corrections referenced to the National Geodetic Survey (NGS) Continuously Operating Base Station (CORS), ZSU4, located approximately 2.5 kilometers from the study area(https://geodesy.noaa.gov/CORS/). The mean reported horizontal precision of these measurements was 0.020 meters (with a standard deviation of 0.003 meters). The magnitude of additional errors resulting from uncertainty in the base station reference position, errors in tripod centering, and antenna height measurement errors are unknown. 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 20 North (NAD83(2011)/UTM Zone 20N) coordinate system, with a resolution of 1 meter. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: PPK equipment collected in field activity 2018-670-FA were used to validate the extrinsic camera calibration using corrections referenced to the National Geodetic Survey (NGS) Continuously Operating Base Station (CORS), ZSU4, located approximately 2.5 kilometers from the study area. The mean reported vertical precision of these measurements was 0.045 meters (with a standard deviation of 0.011 meters). The magnitude of additional errors resulting from uncertainty in the base station reference position, errors in tripod centering, and antenna height measurement errors are unknown. 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 Puerto Rico Vertical Datum of 2002 (PRVD02; EPSG:1123), derived using GEOID12B, coordinate system, with a resolution of 0.001 meters. Lineage: Process_Step: Process_Description: The CoastCam was used to take IO photos. This involves slightly tilting a printed checkerboard with 30-millimeter (mm) squares in various parts of the cameras field of view. An example image can be found in IslaVerdePR_c1_20181106_calibrationIOEO_exampleImagery.zip. There are a total of 58 IO images (IslaVerdePR_c1_20181105_IO.zip) of which 55 were used for the intrinsic calibration. The 55 images were used in step A in the Camera Calibration procedures outlined in Bruder and Brodie (2020). The resultant parameters are stored in a YAML file located in IslaVerdePR_c1_20181105_IO.zip. Image file naming format follows “IslaVerdePR_c1_20181105_###”, 20181105 is the date that the images were taken (YYYYMMDD format) and ### is the original unique ID from the camera.

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. Multiple large square targets painted white and black in opposite quadrants were laid flat on the beach to be visible by the CoastCam. The GNSS receiver was placed on a fixed-height survey rod and set to record observations for one minute at each ground control point at the center of each target (between black and white). After the survey, concurrent GNSS observations were downloaded from the National Geodetic Survey (NGS) Continuously Operating Base Station (CORS), ZSU4, located approximately 2.5 kilometers from the study area. These data were then used to post-process the GNSS measurements using the Trimble Business Center ver. 5.00 software package. The CoastCam took pictures of the position of each target within the camera view (raw JPEG image). The CSV file was used to hand label the raw images to generate annotated images 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, solved in Step B of Bruder and Brodie (2020), the GNSS positions from the CSV files, and the IO parameters in the IO YAML 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 a YAML file located in “IslaVerdePR_c1_20181106_EO.zip”.

The filename for each IO image is formatted as "IslaVerdePR_c1_20181105_###", where 20181105 is the date that the images were taken (YYYYMMDD format) and the number (###) is the original photo ID. There are a total of 2 extrinsic orientation (EO) JPEG images. The filename for each EO image is formatted as "IslaVerdePR_c1_20181106_IslaVerdePR_GCP_image_imagetype", where the "_imagetype" is either 'raw' or 'annotated'. These images have EXIF and other imagery header information encoded within each file, see the process steps for more information. Entity_and_Attribute_Detail_Citation: The entity and attribute information were generated by the individual and/or agency identified as the originator of the dataset. Please review the rest of the metadata record for additional details and information. Overview_Description: Entity_and_Attribute_Overview: 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. The elevation and position of the lenses in the CoastCam setup were measured with the PPK GNSS. The CoastCam took pictures of the position of each target within the camera view. The '_EO' zip folder contains the GCP CSV file, the resultant EO parameters in a YAML file, and a 'raw' and 'annotated' image of the GCPs. The CSV file (IslaVerdePR_c1_20181106_EO_GCPsurvey.csv) with all the measurements were populated and GCP numbers were hand labeled on the annotated image (IslaVerdePR_c1_20181106_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 2 JPEGs. Images have EXIF and other imagery header information encoded within each file, see the process steps for more information.
