Online_Linkage: https://doi.org/10.5066/P9M3NYWI Description: Abstract: Two digital cameras were installed at Unalakleet, Alaska as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras were installed on a windmill tower at a height of approximately 12 meters above the ground surface in August 2018, facing westward from the coast near downtown Unalakleet with overlapping fields of view. When properly functioning, the cameras collected 10 minutes of imagery at 2 Hz and produced image products every half hour. This dataset includes the raw imagery products and the necessary intrinsic orientation (IO) and extrinsic orientation (EO) calibration data to utilize the imagery to make quantitative measurements from the imagery. USGS researchers analyzed 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. These cameras are part of the USGS CoastCam network, supported by Total Water Level, Alaska Coastal Hazards, and Remote Sensing Coastal Change Projects, under the USGS Coastal and Marine Hazards and Resources Program, Natural Hazards Mission Area. Purpose: Data were obtained to document interannual changes in shoreline position and coastal morphology. These imagery data, calibration files, and ground control point (GCP) locations are the extrinsic orientation (geolocation) data and intrinsic orientation (camera parameters) data to produce orthorectified image products that can be viewed in a geographic information system (GIS) or other software to identify topographic and shallow-water bathymetric features. Supplemental_Information: The bounding coordinates below represent the approximate limits of the overlapping images from CoastCam Unalakleet. Throughout the course of the deployment the cameras can move due to changes in temperature, wind, or other factors. To limit the effect of camera movements on data products, we recommend the user calculate their own EO data based on the dates of the imagery used. Images from c1 and c2 have their extrinsic locations in the Exif tag UserComment in NAD83(2011) UTM Zone 4N, NAVD88 GEOID12B, which are used by the imaging toolbox to georectify the images into real world coordinates. GCP information and EO .yaml files are in NAD83(2011) UTM Zone 4N, NAVD88 GEOID12B.

Online_Linkage: https://doi.org/10.1016/j.softx.2020.100582 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Extrinsic orientation (EO) calibration is assessed using GCPs visible in the camera FOV. GCP locations were determined with Real-Time Kinematic (RTK) Global Navigation Satellite System (GNSS) equipment. Accuracy of the extrinsic calibration was also tied to the human ability to locate targets in the imagery when using the Coastal Imaging Research Network (CIRN) Quantitative Coastal Imaging Toolbox (Bruder and Brodie, 2020). Calibration success can be examined using the CIRN toolbox where parameters azimuth, tilt, and roll have errors less than 2 degrees. 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 as YAML Ain't Markup Language (YAML)files, which can be opened with any text viewer, and are named with the calibration date. Logical_Consistency_Report: The camera system installed (two FLIR Blackfly BFLY-PGE-31S4C color cameras) had an extrinsic (EO) and intrinsic (IO) calibration process. The IO calibration process was completed on 20180824 for Unalakleet c1 and c2 and is provided as a set of JPEG images with a checkerboard pattern in different parts of the image. These are used with the Camera Calibration Toolbox for Matlab (https://data.caltech.edu/records/jx9cx-fdh55) to solve for the intrinsic parameters and lens distortion, which are provided in a YAML file of resultant IO parameters. Significant figures are taken as provided by the toolbox. A checkerboard pattern was used and the lens distortion was solved for 3 radial coefficients and 2 tangential coefficients. These are used in the CIRN toolbox steps A through C to georectify imagery and make quantifiable measurements. The intrinsic parameters “coU” and “coV” are used by CIRN, but the same parameters are inconsistently named (for example, cOU/cOV, Cx/Cy, u0/v0) within the broader camera community and may cause issues in running code. The EO calibration process was completed four times (20180825, 20210903, 20230830, 20240607), and EO calibration may be performed additional times in the future. Users can determine the dates of future calibrations from the labelling of the products (“unalakleet_c#_yyyymmdd”, where “c#” is camera number – c1 or c2 – and “yyyymmdd” is the date formatted as 4-digit year, 2-digit month, and 2-digit day). This dataset consists of YAML files of resultant EO parameters from the CIRN Quantitative Coastal Imaging Toolbox steps B and C (Bruder and Brodie, 2020), a comma-separated values (CSV) file of GCP locations and description, and images from the station labeled as 'raw' and 'annotated' showing the GCP targets that were surveyed. Completeness_Report: Significant figures in the YAML files are as provided by the Camera Calibration Application. All IO calibration images are provided, but not all may be necessary in the CIRN Toolbox. Surveyed GCP locations and images are provided for the EO calibration surveys. Horizontal coordinates of the GCPs were referenced to the North American Datum of 1983 (National Spatial Reference System 2011) Universal Transverse Mercator Zone 4 North (NAD83(2011)/UTM Zone 4N) coordinate system (Epoch 2010.00) as to be ingested in the CIRN Toolbox. The camera pole (not the individual cameras) was located with the RTK equipment at 63.875909 N, 160.7955352 W EPSG:6318 NAD83 (2011). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Ground control points for the EO calibration are generally taken with GNSS survey equipment; points typically have a 5 cm or better horizontal accuracy. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Ground control points for the EO calibration are generally taken with GPS survey equipment; points typically have a 10 cm or better vertical accuracy. Lineage: Process_Step: Process_Description: Before installation at Unalakleet, c1 and c2 were used to take a series of photos for the IO calibration. This process consisted of collecting and analyzing sample images. These images contain a square checkerboard moved throughout the image frame. This checkerboard pattern allows lens distortion metrics to be calculated. The image file name is formatted as unalakleet_c#_YYYYMMDD_IO_####.jpg where c# is the camera number, YYYYMMDD is the date the IO images were obtained, and #### is the original number written to the file. Note that the time and location of where the actual photos were taken is irrelevant; they have been tagged with the GPS location of the camera pole for which they are relevant and given a GPSTimeStamp of 12:00:00. Process_Date: 20260512 Process_Step: Process_Description: 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, multiple stationary targets, between 5 and 10 per camera as recommended by Brodie and Bruder (2020), were spread through the camera FOV to be used as GCPs. Survey targets (a square consisting of two black and two white triangles) were placed on the beach within the field of view of the CoastCam station. These were measured with RTK GNSS at the intersection of the sand and the middle of the target. Once all GCPs were placed, a snapshot (“snap”) was taken with the camera. The image file name is formatted as unalakleet_c#_YYYYMMDD_GCP_image_type.jpg where “c#” is the camera number, “YYYYMMDD” is the date the EO images were obtained, and “type” is raw or annotated. Process_Date: 20260512 Process_Step: Process_Description: The IO images together with the GCP targets from the EO surveys were used in the CIRN Toolbox and with the Camera Calibration App (MATLAB) to solve for the 3 radial coefficients and 2 tangential coefficients that make up the intrinsic parameters and lens distortion and the EO parameters. The IO coefficient values are provided in YAML files for each camera (unalakleet_c#_yyyymmdd_IO.yaml) and the EO parameters are provided in YAML files for each camera (unalakleet_c#_yyyymmdd_EO.yaml), where “c#” as c1 or c2, and “yyyymmdd” is the date of the survey. These YAML files can be re-solved for using the raw images and survey data provided in the CIRN Toolbox. Please refer to Brodie and Bruder (2020) for information about the methods. Step processed by Athina Lange. Process_Date: 20260512 Process_Step: Process_Description: All images were geotagged and processed to add additional information required by the USGS to the exchangeable image file format (EXIF) and other imagery headers using exiftool (https://exiftool.org version: 13.57).
