Every hour during daylight hours, daily from June 26, 2018, to September 20, 2018, 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 visit https://www.usgs.gov/programs/cmhrp/science/usgs-coastcams. 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); 2018-617-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=2018-617-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 20180625 (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 20180626 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 72 images and the extrinsic calibration uses one “timex” photo with GCP targets that have pre-established location information. Of the 72 photos, 62 images that collectively covered the entire image frame were selected to solve for the intrinsic calibration. The 10 images excluded were: MolokaiHI_c2_20180625_041.jpg, MolokaiHI_c2_20180625_047.jpg, MolokaiHI_c2_20180625_051.jpg, MolokaiHI_c2_20180625_055.jpg, MolokaiHI_c2_20180625_076.jpg, MolokaiHI_c2_20180625_080.jpg, MolokaiHI_c2_20180625_088.jpg, MolokaiHI_c2_20180625_116.jpg, MolokaiHI_c2_20180625_133.jpg, and MolokaiHI_c2_20180625_138.jpg. These were used in the CIRN Toolbox steps A through C. Results of the intrinsic and extrinsic calibrations are stored in separate YAML files (MolokaiHI_c2_20180625_IO.yaml, MolokaiHI_c2_20180626_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 2018-617-FA were used to validate the extrinsic camera calibration using corrections referenced to a GNSS base station occupying a temporary benchmark (MK02) located approximately 1 kilometer (km) from the study area. Reference coordinates for MK02 were established using the mean position derived from four static GNSS occupations with durations greater than 4 hours each submitted to the National Geodetic Survey Online Positioning User Service (NGS OPUS). The standard deviation of the four OPUS-derived horizontal positions was 0.004 meters. The mean reported horizontal precision of the PPK measurements was 0.015 meters (standard deviation of 0.002). 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 PA11) Universal Transverse Mercator Zone 4 North (NAD83(PA11)/UTM Zone 4N) coordinate system, with a resolution of 0.001 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: PPK equipment collected in field activity 2018-617-FA were used to validate the extrinsic camera calibration using corrections referenced to a GNSS base station occupying a temporary benchmark (MK02) located approximately 1 kilometer (km) from the study area. Reference coordinates for MK02 were established using the mean position derived from four static GNSS occupations with durations greater than 4 hours each submitted to the National Geodetic Survey Online Positioning User Service (NGS OPUS). The standard deviation of the four OPUS-derived vertical positions was 0.008 meters. The mean reported vertical precision of the PPK measurements was 0.022 meters (standard deviation of 0.002). 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 orthometric heights relative to local mean sea level, derived using GEOID12B, coordinate system, with a resolution of 0.001 meters. Following OCM Partners (2024), the orthometric elevation was converted from GEOID12B to a local mean sea level by subtracting 0.601 meters. The GEOID12B to local mean sea level vertical adjustment for Moloka'i was derived by OCM Partners (2024) from published National Geodetic Survey control point datasheets. 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 MolokaiHI_c2_20180626_calibrationIOEO_exampleImagery.zip. There are a total of 72 IO images (MolokaiHI_c2_20180625_IO.zip) of which 62 were used for the intrinsic calibration. The 62 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 MolokaiHI_c2_20180625_IO.zip. Image file naming format follows “MolokaiHI_c2_20180625_###”, 2018-06-25 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 round targets painted white and black in opposite quadrants were put into the camera field of view to be visible by the CoastCam. One 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). A second GNSS receiver, serving as a base station, was placed on a fixed-height rod and placed on a temporary benchmark (MK02) approximately 1 kilometer from the survey area. The base receiver was programmed to record raw GNSS observations during survey operations. Reference coordinates for MK02 were established using the mean position derived from four static GNSS occupations with durations greater than 4 hours each submitted to the National Geodetic Survey Online Positioning User Service (NGS OPUS). These data were then used to post-process the GNSS measurements using the Trimble Business Center ver. 4.30 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 “MolokaiHI_c2_20180626_EO.zip”.

The filename for each IO image is formatted as "MolokaiHI_c2_20180625_###", where 2018-06-25 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 "MolokaiHI_c2_20180626_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 antenna. 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 (MolokaiHI_c2_20180626_EO_GCPsurvey.csv) with all the measurements were populated and GCP numbers were hand labeled on the annotated image (MolokaiHI_c2_20180626_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.
