Online_Linkage: https://doi.org/10.5066/P17OF3UP Online_Linkage: https://www.sciencebase.gov/catalog/item/67a2878dd34e05baae1c8705 Description: Abstract: Two digital video cameras were installed at Marconi Beach, Cape Cod National Seashore (CACO) in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras faced north/north-east (c1) and north-east/east (c2) along the beach and collected images for 17 minutes at 2Hz every half hour during daylight hours. They ran daily from March through June 2021, February through July 2023 and January through September 2024; the cameras collected raw images 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. 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. These cameras are 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 site visit https://www.usgs.gov/centers/whcmsc/science/using-video-imagery-study-marconi-beach. Purpose: Data were obtained to document interannual changes in shoreline position and coastal morphology. These data are intended for science researchers, students, policy makers, and the public. These data can be further 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. Supplemental_Information: The bounding coordinates below represent the approximate limits of the rectified images from the CoastCam. The cameras were initially positioned to maintain approximately 7.5m of cliff toe overlap in their field of view (FOV). The intrinsic calibration photos were taken on 20210225 for the 2021 and 2023 deployments and on 20240105 for the 2024 deployment and their location information is not consequential. For each deployment (2021, 2023, and 2024), the cameras were positioned pointing roughly north-east (c1) and east (c2), however each deployment should be considered separately with regards to extrinsic calibration. IO/EO information is provided in the image EXIF headers as calculated from Bruder and Brodie (2020), however we recommend to the user to calculate their own EO data based on the dates of the imagery used. Please see CACO02_calibration_metadata for necessary IO/EO information. All camera images are geotagged with the general location of the CACO02 camera pole in geographic coordinates NAD83(2011), images from c1 and c2 have their extrinsic locations in the Exif tag UserComment in NAD83(2011)/UTM 19N + NAVD88, which are used to put the images into real world coordinates when georectifed. Throughout the course of the deployment the cameras can move due to changes in temperature, wind, or other factors.

Online_Linkage: https://doi.org/10.1016/j.softx.2020.100582 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The video cameras collected 5-megapixel images, with file sizes generally between 0.1 and 1.3 megabytes (MB) on disc. Images may be obscured by water droplets, insects, birds, salt, sand and dirt, poor visibility from adverse weather conditions or sun glare, and thus may not reflect the true state of the beach and ocean. Logical_Consistency_Report: The camera system installed (FLIR Blackfly S) was programmed to collect three-band images every half hour during daylight hours and take video for 17 minutes. Each time the camera was activated there were five resultant image products collected: snap, timex, var, bright, and dark images. See the Process Steps for more information about these image types. Completeness_Report: The imagery represents a fixed location at Marconi Beach, MA. Images may not be available every half hour of operation due to camera malfunction. Images may be obscured by water droplets, insects, birds, salt, sand and dirt, poor visibility from adverse weather conditions or sun glare, and thus may not reflect the true state of the beach and ocean. The cameras were deployed at the same location three times: March - June 2021, February - July 2023 and January - September 2024. Throughout the course of each deployment the cameras can move due to changes in temperature, wind, or other factors. This product is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The camera pole location: This is embedded in all images GPSLatitude and GPSLongitude Exif information, which was measured with a Real-Time Kinematic (RTK) Global Positioning System (GPS) equipment and is accurate to 2 cm. This value is 41 deg 53' 33.44" N, 69 deg 57' 47.50" W EPSG:6318 NAD83(2011) and is used to generally locate CACO02. Camera c1 and c2 EO location: The horizontal accuracy of the camera's external orientation, which is embedded in the Exif tag UserComment, was verified using data collected in field activities 2021-019-FA, 2021-022-FA, 2023-006-FA and 2024-002-FA and processed with the CIRN Quantitative Coastal Imaging Toolbox (Bruder and Brodie, 2020) which reports horizontal +/- error estimates less than 1 meter. These are available in the CACO02_calibration_metadata record included in the larger work citation. Horizontal coordinates were referenced to NAD83(2011)/UTM Zone 19N (Epoch 2010.00), with a resolution of 0.001 meters. These EO horizontal values are used to place the images into real world coordinates when georectified. Lineage: Process_Step: Process_Description: Before mounting the CoastCam at the beach, the cameras (FLIR Blackfly S) were used to take intrinsic camera calibration images. Please refer to the CACO02_calibration_metadata record included in this data release for more information on the calibration process. The camera system consists of two FLIR Blackfly S cameras which were installed on a bluff overlooking Marconi Beach, approximately 200 meters north of the staircase landing on 20210304, 20230213 and 20240105. The cameras were deployed on a telescoping mast and aligned for an approximate 15 degrees overlapping view. The cameras are connected to an Intel NUC acquisition and control computer, powered by a solar charging system comprised of lithium batteries, a Renogy Voyager solar charge controller, and Renogy 100W solar panels. Intrinsic calibration was processed by A.M.Z. Lange. Process_Date: 20210304 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Athina M.Z.

The images included in this data release were collected from March 4th 2021 to June 3rd 2021, February 13th 2023 to July 20th 2023 and January 5th 2024, to September 8th 2024. Gaps may exist in each dataset due to camera malfunction. Additionally, some images may have been obscured by water droplets, insects, birds, salt, sand and dirt, poor visibility from adverse weather conditions, or sun glare, and thus may not reflect the true state of the beach and ocean. Each time the camera was activated, there were five resultant image products collected: the "snapshot" ("snap") image is the first frame of the video; the time exposure ("timex") image is the average of all frames within the 17 minute video; the "variance" ("var") image shows the standard deviation of pixel intensity throughout the video; the brightest ("bright") image shows the brightest pixel values throughout the video; and the darkest ("dark") image shows the darkest pixel values throughout the video. The local control computer acquires, produces, and stores the images and products and twice per hour syncs data to the AWS cloud server. The data is transmitted to the remote storage server via a Sierra Wireless cellular modem. Step was processed by C.R. Sherwood.

Additionally, there were tags added to the Python dictionary object that would have a different value for each image depending on factors such as the file type and/or date when the image was captured. These tags and an example value are included as follows, as well as a description for why the values differ, as needed: 'PreservedFileName': '1718201520.Wed.Jun.12_14_12_00.GMT.2024.caco-02.c1.snap.jpg'; 'Caption-Abstract': 'The snapshot image represents the first frame of the 17 minute video.

All the Joint Photographic Experts Group (JPEG) images were renamed to ensure unique filenames and compliance with the USGS Coastal and Marine Hazard and Resources Program's (CMHRP) best practices for image naming convention. Images were renamed with the image acquisition date and Greenwich Mean Time (GMT) in computer and human readable format, the camera location, the camera number, and the image type that distinguishes among the five image product types. For example, image name '1718201520.Wed.Jun.12_14_12_00.GMT.2024.caco-02.c1.snap.jpg', where 1718201520 is the 10-digit epoch time convention of the date and time, Wed is the three character day of the week, Jun is the three character month, 12 is the two digit day of the month, 14_12_00 is the GMT time in HH_MM_SS format, 2024 is the year, caco-02 is the camera location, c1 is the camera number, and snap is the image type. The UserComment EXIF metadata field was used to store the camera intrinsics and extrinsics in the image metadata. The UserComment has a nested dictionary structure. The highest-level dictionary contains two nested dictionaries as well as a note explaining the structure of the UserComment field. One nested dictionary contains the relevant intrinsic (NU, NV, coU, coV, fx, fy, d1, d2, d3, t1, t2) and extrinsic (x, y, z, azimuth, tilt, roll) data variables. See CACO02_calibration_metadata for descriptions of variables. The extrinsic variables include both horizontal and vertical location of the camera in NAD83(2011)/UTM 19N + NAVD88 (GEOID 18). We recommend to the user to calculate their own EO data based on the dates of the imagery used. The other nested dictionary contains text descriptions for each of the variables in the dictionary of data variables. The calibration date and GPS DateStamp field indicates the date of the EO. The field activity numbers in the Image Description and Description are relative to the deployment; 2021: 2021-019-FA and 2021-022-FA; and 2024: 2024-002-FA. The camera pole location was surveyed with RTK gear, which gives us the UTM and Lat/Long simultaneously in the file we download off of the device. The EXIF GPS Latitude/Longitude/Position tags are in NAD83(2011). To read out the imagery header information to a comma-separated values (CSV) file with exiftool, the command is: 'exiftool -csv *.jpg > .\ allheaders.csv'. Specific tags may be specified with this command, if preferred. Step processed by A.M.Z. Lange.
