Online_Linkage: https://doi.org/10.5066/P9GEVWG1 Description: Abstract: These data map the beach and nearshore environment at Head of the Meadow Beach in Truro, MA, providing updated regional context for the 2019 CoastCam installation. 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 2022-015-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region. In March 2022, 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 (Sony a6000) and a post-processed kinematic (PPK) system attached to a helium filled balloon-kite (Helikite). High-precision GPS targets (AeroPoints) and numbered black and white tarps 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 surface vehicle. Agisoft Metashape (v. 1.8.1) was used to create a digital surface model with the collected which was merged with the bathymetry in MATLAB (v. 2020b) to create a continuous topobathy product. Purpose: This topobathymetric elevation grid represents the bluffs, dunes, beach, and nearshore of Head of the Meadow Beach in view of the CoastCam.

Lineage: Process_Step: Process_Description: The 25 cm Digital Surface Model (DSM) 2022015FA_Truro_DSM_25cm.tif and 1 m bathymetry grid 2022015FA_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 (used 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 returns the mask as a binary image, setting pixels inside the region of interest polygon to 1 and pixels outside the region of interest (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 bathymetry 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 exported in NAD83(2011)/UTM Zone 19N in NAVD88 meters, using Geoid 12B. Note that using NAVD88 as a height means that the depths are not true-depths but the elevation of the seafloor above or below the geoid. Schwanghart, W., Scherler, D.
