Every hour during daylight hours, the cameras 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 images included in this data release were collected by camera 2 (c2) from May 29, 2018, to October 16, 2022. The cameras are part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment (https://www.usgs.gov/coastcams). USGS researchers utilize the imagery collected from these cameras 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, 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/spcmsc/science/using-video-imagery-study-coastal-change-sand-key-florida. 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; 2018-328-FA. Additional information about this FAN from which the extrinsic orientation (EO) calibration data were derived is available on the Coastal and Marine Geoscience Data System (CMGDS): https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-328-FA. Additionally, a FAN was assigned for the camera imagery collection, 2018-302-DD, and more information is available here: https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-302-DD. 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 on 20180413 and their location information is not consequential.

Brodie Publication_Date: 20200909 Title: CIRN Quantitative Coastal Imaging Toolbox Geospatial_Data_Presentation_Form: publication Publication_Information: Publication_Place: Online Publisher: Elsevier SoftwareX Online_Linkage: https://doi.org/10.1016/j.softx.2020.100582 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Extrinsic orientation (EO) calibration ground control points (GCPs) were surveyed with a Spectra Precision SP80 Global Navigation Satellite System (GNSS) Real-Time Kinematic (RTK) receiver. 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. Calibration data is stored in YAML files named with the calibration date.. Logical_Consistency_Report: The camera system installed (FLIR Blackfly 5.0MP Color GiGE PoE, BFLY-PGE-50S5C-C) had an intrinsic and extrinsic calibration process. The EO process was completed on 20180419 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 30 images that collectively covered the entire image frame and the extrinsic calibration uses one “darkest” photo with GCP targets that have surveyed location information. These were used in the CIRN Toolbox steps A through C. Results of the intrinsic and extrinsic calibrations are stored in separate YAML files (sandkey_c2_20180413_IO.yaml, and sandkey_c2_20180419_EO.yaml). 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: RTK equipment with decimeter horizontal accuracy collected data in field activity 2018-328-FA was 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 17 North (NAD83(2011)/UTM Zone 17N) coordinate system. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: RTK equipment with centimeter vertical accuracy collected in field activity 2018-328-FA was 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 was used to take IO photos. This involves slightly tilting a printed checkerboard with 2.7-centimeter (cm) squares in various parts of the cameras field of view. An example image can be found in sandkey_c1_calibrationIOEO_exampleImagery.zip. There are a total of 30 IO images (sandkey_c2_20180413_IO.zip) used for the intrinsic calibration. These 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 sandkey_c2_20180413_IO.zip. Image file naming format follows “sandkey_c2_20180413_IO_##”, where sandkey is the site name, c2 is the camera name, 20180413 is the date the images were taken (YYYYMMDD format), IO is Intrinsic Orientation, and ## is the original unique ID from the camera.

GCPs were collected on 20180419. 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, a single large square target (1.2 m by 1.2 m) painted white and black in opposite quadrants was propped up to face the CoastCam setup at multiple locations within the camera field-of-view to collect ground control points. At each GCP location, a snapshot was taken with the camera of the position of the target (sandkey_c2_20180419_GCP##.jpg); additionally, the bottom-center of the target (between black and white, at ground level) was measured with the RTK GPS equipment. A single image showing all GCP locations (sandkey_c2_20180419_GCP_image_raw.jpg) was made by creating a “dark” image using all of the snapshots of the target. The survey locations of the GCPs in the CSV file was used to hand label the raw image to generate an annotated image (sandkey_c2_20180419_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 at bottom-center of targets), solved in Step B of Bruder and Brodie (2020), the GPS 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 “sandkey_c2_20180419_EO.zip”.

The filename for each IO image is formatted as "sandkey_c2_20180413_IO_##", where the number (##) is the original photo ID. There are 15 extrinsic orientation (EO) JPEG images (sandkey_c2_20180419_GCP_image_raw.jpg, sandkey_c2_20180419_GCP_image_annotated.jpg, and sandkey_c2_20180419_GCP##.jpg for GCPs 1-13). 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 RTK GPS. 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, 'raw' and 'annotated' images showing all the GCPs, and individual images of the target at each GCP location. The CSV file (sandkey_c2_20180419_EO_GCPsurvey.csv) with all the measurements were populated and GCP numbers were hand labeled on the annotated images (sandkey_c2_20180419_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 15 JPEGs. Images have EXIF and other imagery header information encoded within each file, see the process steps for more information.
