Description:
Abstract:
Two digital video cameras were installed at Sand Key, Florida (FL), facing south (camera 1) and north (camera 2) along the beach. Every hour during daylight hours, daily from 2018 to 2022, the cameras collected raw video and produced snapshots and time-averaged image products. For camera 2, one such product that is created is a "runup timestack". Runup timestacks are images created by sampling a cross-shore array of pixels from an image through time as waves propagate towards and run up a beach. Runup timestacks store the red, green, and blue or monochrome pixel intensity as a function of the cross-shore position as imagery for the sampling period, typically around 10 minutes to 1 hour. This data release includes timestack imagery fom camera 2 and the corresponding world coordinate data needed 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 utilize the timestack imagery collected from these cameras to remotely sense information such as wave runup. This camera is part of the USGS CoastCam network, supported by 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:
Data were obtained to measure wave runup along a cross-shore transect. These data are intended for science researchers, students, policy makers, and the public. These data can be further processed to calculate wave runup. To ensure that USGS St. Petersburg Coastal and Marine Science Center (SPCMSC) data management protocols were followed, a USGS Field Activity Number was assigned (FAN) for this camera imagery collection: 2018-302-DD. Additional information about this FAN is available on the Coastal and Marine Geoscience Data System (CMGDS): https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-302-DD. Additionally, a FAN was assigned for the intrinsic orientation (IO) and extrinsic orientation (EO) calibration data, 2018-328-FA, and more information is available here: https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-328-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. This dataset represents the timestack images (in Network Common Data Form format (netCDF, .nc)) collected from the USGS CoastCam at Sand Key, FL. More timestack images will be added to this release as it is collected and processed.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The video camera collected 5-megapixel images. 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, BFLY-PGE-50S5C-C) was programmed to collect three-band images every hour during daylight hours and take video for approximately 17 minutes. A timestack image for the 17-minute period was created by sampling a single transect on the beach.
Completeness_Report:
The imagery represents a fixed location at Sand Key, FL. Images may not be available every 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. 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.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of the camera's external orientation was verified using data collected in field activity 2018-328-FA and processed with the CIRN Quantitative Coastal Imaging Toolbox (Bruder and Brodie, 2020). An extrinsic calibration survey was performed at the Sand Key site on April 19, 2018. Horizontal accuracy was obtained by comparing the ground control points from the extrinsic calibration surveys in the Brown and others (2024) to user selected ground control points in the camera images. For the April 19, 2018, survey: the mean x error is 4.16 meters, and the mean y error is 12.34 meters. Please refer to the sandkey_c2_20180419_EO zip file and the sandkey_c2_calibration_metadata record included in Brown and others (2024) for more information. 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. Additionally, coordinates in the local coordinate system, as well as latitude and longitude (WGS84), are included. These additional coordinates are derived from the UTM coordinates.

Process_Description:
Before mounting the CoastCam at the beach, the camera (FLIR, BFLY-PGE-50S5C-C) was used to take intrinsic camera calibration images. Please refer to the sandkey_c2_20180413_IO zip file and the sandkey_c2_calibration_metadata record included in Brown and others (2024) for access to the intrinsic camera calibration data and more information on the calibration process. After calibration was complete, the camera mount was installed on the rooftop of Dan’s Island Condominium building (1600 Gulf Blvd, Clearwater, FL 33767) on 20180413. The camera was installed and connected to a control computer, wall powered, and wired ethernet connection in an interior room of the facility. The control computer was connected to a hard drive to transfer the images upon collection.

Process_Description:
The camera was programmed to collect three-band (RGB) images at 2 Hertz (Hz) for a total of approximately 17 minutes (2048 images), every hour during daylight hours. The images included in this data release were collected from May 29, 2018, to November 5, 2021. Gaps may exist in the dataset due to power disruptions or 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 hour the camera was activated, a timestack image product was produced by sampling intensity values at a single transect of pixels, defined by (U,V) pixel coordinates, from the 2048 images and saved in Tag Image File Format (TIFF, .tiff). The (U,V) sampling locations were determined by identifying a cross-shore transect of locations in local horizontal (X,Y) coordinate system, which aligned with the local shoreline orientation. The elevation of samples was chosen as Z = 0 m, which is an elevation assumed to be near the water line. The vertical reference frame was NAVD 88 coordinate system. XYZ-sampling locations were projected into (U,V) image coordinates following established methods (Palmsten and Brodie, 2022; Bruder and Brodie, 2020) and using camera extrinsic calibration information (sandkey_c2_20180419_EO) from Brown and others (2024). To create the timestacks, the raw images were saved on the control computer’s hard drive, then processed locally to produce one timestack per hour. The timestacks were then sent via internet to a U.S. Geological Survey internal File Transfer Protocol (ftp) site, where they were then automatically downloaded from the ftp site to the SPCMSC servers for archiving.

Process_Description:
The TIFF timestacks were processed to add additional information using the netCDF4 Python library version 1.6.4. The times of the collection, sampled at 2 Hz, were stored as a one-dimensional (1D) array, where each index of the array contained a time represented as epoch time, seconds elapsed since 00:00:00 UTC on January 1, 1970. The sampling locations, saved as local XYZ values, were stored as a two-dimensional array. Because pixels were stored assuming an elevation of Z = 0 m and the true beach surface may vary, and additional processing step was needed to project the sampling locations onto a topo-bathymetric surface representative of the beach at the time of the image data collection following previously described methods (Palmsten and Brodie, 2023; and Holland and others, 1997). The topo-bathymetric surface was developed from GNSS survey data collected within the field-of-view of the camera (Birchler and others, 2024) and lidar data (National Geodetic Survey, 2024). The point data was interpolated onto a grid using the method described by Plant and others (2002) with smoothing length scales of 1 m in the cross-shore direction and 40 m in the alongshore direction. The local (X,Y) coordinates were rotated and translated into UTM coordinates using information describing the local origin and rotation angle for the Sand Key site, where the horizontal reference frame (X,Y) was NAD83(2011)/UTM Zone 17N. The (X,Y) coordinates were also translated from UTM to WGS84 latitude and longitude coordinates using the UTM Python library version 0.7.0. One netCDF(.nc) file was created for each timestack image using the netCDF Python library. The data included in each netCDF file includes the timestack image; the UV image coordinates, the XY coordinates in UTM; the XY local coordinates; the latitude and longitude coordinates; the Z-elevation coordinates projected onto the beach surface; and an array of the epoch times as previously described. Additional metadata was included in the netCDF files as global and variable attributes using the Climate and Forecast (CF)-compliant metadata convention (version CF-1.6). These attributes describe the data collection, as well as how the different coordinate systems are used within the data.
