CoastCam CACO-01 are two video cameras aimed at the beach that view the coast shared by beachgoers, shorebirds, seals, and sharks. These data were collected as part of field activity 2021-014-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region. In February 2021, U.S. Geological Survey and Woods Hole Oceanographic Institute (WHOI) scientists conducted field surveys to re-map the field of view of the CoastCam. Aerial images of the beach for use in Structure from motion were taken with a camera (Ricoh GRII) and a post-processed kinematic (PPK) system attached to a helium powered balloon-kite (Helikite). High-precision GPS targets (AeroPoints) were used as ground control points. Bathymetry was collected in the nearshore using a single-beam echosounder mounted on a surf capable self-righting electric autonomous Small Surf Vehicle (SSV). Agisoft Metashape (v. 1.7.2) was used to create a digital elevation model with the collected imagery and this was merged with the bathymetry in MATLAB (v. 2020) to create a continuous topobathy product. Purpose: Elevation dataset for use by the public, researchers, and others to observe ground conditions and temporal change of the bluffs, dunes, beach, and nearshore of Head of the Meadow Beach in view of the CoastCam setup. Supplemental_Information: Bounding coordinates are based on image positions and may not the reflect full extent of the final product.

Online_Linkage: https://doi.org/10.5066/P9KSG1RQ Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The GNSS used on the SSV and to collect the imagery used to model the topography has theoretical vertical and horizontal accuracies of 2-5 cm, but horizontal accruacy is generally less accurate. See the bathymetry and imagery datasets and metadata in the larger work citation for more details. Logical_Consistency_Report: This file represents the merged and interpolated 1-meter pixel resolution single beam echo-sounder bathymetry data and digital surface model (DSM) created from imagery collected by Peter Traykovski of WHOI. These data are post-processed kinematic (PPK) orthometric heights collected using a GNSS receiver (EMLID Reach M2) corrected to a base station (JAVA Triumph) onshore in GEOID 12B NAVD88 (m). Completeness_Report: This product represents the full extent of the topography and bathymetry available in the larger work citation. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Navigation information was acquired from a GNSS receiver (EMLID Reach M2) in PPK mode with a Multi-band GNSS antenna that has an estimated horizontal accuracy of 2-5 m. See larger citation imagery, DSM, and bathymetry metadata for more information. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The location information was acquired from a GNSS receiver (EMLID Reach M2) in PPK mode with a Multi-band GNSS antenna and hot shoe adapter with an estimated vertical accuracy of 2-5 cm. See larger citation imagery, DSM, and bathymetry metadata for more information. Lineage: Process_Step: Process_Description: The 2021014FA_Truro_DSM_25cm.tif and 2021014FA_Truro_bathymetry_1m.tif (available from the larger work citation) were merged and interpolated over a 1 m grid in MATLAB v. 2020b with the following steps. 1. The data (x,y,z) from the DSM and Bathy grids were combined with the interpolation method regularizedata3d (bicubic interpolation) using a smoothness coefficient of 0.001 (appropriate for data with low noise where the input points nearly coincide with the output surface) by Jamal (2020). 2. The combined grid was then masked using 'roipoly' which returned the mask as a binary image, setting pixels inside the region of interest (ROI) polygon to 1 and pixels outside the ROI to 0. The boundary was determined by specifying the polygon vertices as the regularizedata3D outputs (x,y,z) from the previous step and prevented extrapolation beyond the tracklines of the Bathy and DSM extent. 3. The final merged GeoTIFF was created using the GRIDobj tool in the TopoToolbox (Schwanghart and Scherler, 2014) which used the interpolated grid from Step 1 and the mask from step 2 to create the final output. The GeoTIFF was output in NAD83(2011)/UTM Zone 19N horizontal coordinate system and in the vertical datum NAVD88 (m). Schwanghart, W., Scherler, D.
