Description:
Abstract: Two digital video cameras were installed at Isla Verde, Puerto Rico (PR); camera 1 faced northeast offshore and camera 2 faced east-northeast along the beach. Every hour during daylight hours, daily starting in August 2022, the camera collected raw video and produced snapshots and time-averaged image products. This metadata record is for camera 2 and includes the necessary intrinsic orientation (IO) and extrinsic orientation (EO) calibration data to utilize 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 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.
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; 2022-330-FA. Additional information about this FAN is available on the Coastal and Marine Geoscience Data System (CMGDS): https://cmgds.marine.usgs.gov/services/activity.php?fan=2022-330-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 the adjacent nearshore area approximately 600 meters (m) directly in line of camera 2 facing alongshore. The intrinsic calibration photos were taken at the deployment site on 20220813 (YYYYMMDD) and their location information is not consequential.

Attribute_Accuracy:
Attribute_Accuracy_Report: EO calibration ground control points (GCPs) were surveyed with Spectra Geospatial SP80 and SP90 Differential Global Positioning System (DGPS) Post-Processed Kinematic (PPK) receivers. Calibration success can be examined using the CIRN QCIT 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 parameters are stored in YML files named with the date first active.
Logical_Consistency_Report: The camera systems installed (FLIR BlackFly S GigE 5MP) had intrinsic and extrinsic calibration processes. The IO calibration process was completed on 20220813 and consists of a total of 351 images for c2. Of the 351 images for c2, 327 images that collectively covered the entire image frame were selected to solve for the intrinsic calibration. These photos are listed in c2_20220813_IO_calibratedImageSet.txt. These photos are used in the CIRN QCIT Toolbox steps A through C. The EO process was completed on 20220814, 20221209, and 20230323 and each date consists of a YML file of resultant EO parameters, a comma-separated values (CSV) file of GCP locations and description, and two Joint Photographic Experts Group (JPEG) images, one labeled as 'raw' and the other as 'annotated'. The extrinsic calibration uses one "snap" photo with GCP targets that have pre-established location information. Results of the intrinsic and extrinsic calibrations are stored in separate YML files (islaverde_c2_20220813_IO.yml, islaverde_c2_20220814_EO.yml, islaverde_c2_20221209_EO.yml, and islaverde_c2_20230323_EO.yml).
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 with decimeter horizontal accuracy collected in field activity 2022-330-FA were used to validate the extrinsic camera calibration. The precise locations of the targets are used in the CIRN QCIT 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.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report: PPK equipment with centimeter vertical accuracy collected in field activity 2022-330-FA were used to validate the extrinsic camera calibration. The precise locations of the targets are used in the CIRN QCIT Toolbox steps B and C (Bruder and Brodie, 2020). Vertical positions are referenced to the Puerto Rico Vertical Datum of 2002 (PRVD02) coordinate system.

Process_Step:
Process_Description: The CoastCams were used to take IO photos. This involves slightly tilting a printed checkerboard with 2.9-centimeter (cm) squares in various parts of the camera's field of view. An example image can be found in islaverde_c2_calibrationIOEO_exampleImagery.zip. There are a total of 351 IO images for c2 (islaverde_c2_20220813_IO.zip) of which 327 were used for the intrinsic calibration. The names of all, calibrated, and excluded images are listed in separate text files. The intrinsic calibration was completed using the MATLAB Computer Vision Toolbox Camera Calibrator application. The output from the calibration was 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 islaverde_c2_20220813_IO.zip. Image file naming format follows "c2_20220813_IO_####_############", where c2 is the camera name, 20220813 is the date the images were taken (YYYYMMDD format), IO is Intrinsic Orientation, and ####_############ is the unique ID from the camera.

Process_Step:
Process_Description: EO calibration GCPs were surveyed with Spectra Geospatial SP80 and SP90 DGPS PPK receivers. GCPs were collected three times after the camera had been operational (20220814, 20221209, and 20230323). 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 lenses in the CoastCam setup were measured with the PPK GPS. Then, a 1.2-meter square target with white and black color in opposite quadrants was propped up to face the CoastCam setup. The bottom center of the target (between black and white) where it met the beach surface was measured with the PPK GPS equipment to collect ground control points. The CoastCam took pictures of the position of each target within the camera view (raw JPEG images). The images were then digitally combined so that all GCPs would appear on a single image. The survey locations of the GCPs in the CSV file were 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 image (hand-selected), solved in Step B of Bruder and Brodie (2020), the GPS positions from the CSV file, 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 each of the three EO calibration dates are stored in a YML file located in "islaverde_c2_YYYYMMDD_EO.zip", where YYYYMMDD is the date for each EO GCP calibration (20220814, 20221209, and 20230323).

Overview_Description:
Entity_and_Attribute_Overview: There are a total of 351 IO TIFF images for c2. The filename for each IO image is formatted as "c2_20220813_IO_####_############", where the number (####_############) is the original photo ID. There are 6 EO JPEG images for c2. The filename for each EO image is formatted as "islaverde_c2_YYYYMMDD_GCP_image_imagetype", where YYYYMMDD is the date and 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 CoastCams 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 approximate elevation and position of the lenses in the CoastCam setup were measured with the PPK GPS. The CoastCams took pictures of the position of each target within the camera view. Each '_EO' zip folder contains the GCP CSV file, the resultant EO parameters in a YML file, and a 'raw' and 'annotated' image of the GCPs. CSV files (islaverde_c2_20220814_EO_GCPsurvey.csv, islaverde_c2_20221209_EO_GCPsurvey.csv, and islaverde_c2_20230323_EO_GCPsurvey.csv) with all the measurements were populated and GCP numbers were hand labeled on the annotated images (islaverde_c2_20220814_GCP_image_annotated.jpg, islaverde_c2_20221209_GCP_image_annotated.jpg, and islaverde_c2_20230323_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 6 JPEG files per camera for a total of 12 JPEGs. Images have EXIF and other imagery header information encoded within each file; see the process steps for more information.
