Abstract:
The data in this release map the beach and nearshore environment at Head of the Meadow Beach in Truro, MA and provide environmental context for the camera calibration information for the 2019 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is related to the field activity 2020-015-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region that falls within the field of view of the CoastCam, which are two video cameras aimed at the beach. On March 4, 6, and 10, 2020, U.S Geological Survey and Woods Hole Oceanographic Institution (WHOI) scientists conducted field surveys to collect position and orientation information for the CoastCam cameras and map the field of view. Elevation data were collected using a real time kinematic – satellite navigation system (RTK-GNSS) receiver attached to a pole and walked on the beach. Point data of the beach face were collected along transects and at periodic locations of plywood targets moved throughout the day within the CoastCam view. Grain-size analysis was performed on sediment samples collected with a spade along multiple profiles from the bluff base to the intertidal zone. Images of the beach were taken with a camera (Ricoh GRII) and a post-processed kinematic (PPK) system attached to a kitesurfing kite, and high-precision 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 survey vehicle. Agisoft Metashape (v. 1.6.1) 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:
This topobathymetric grid represents approximately 0.1778 square kilometers of the bluffs, dunes, beach, and nearshore of Head of the Meadow Beach in view of the CoastCam setup.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The GNSS used on the ASV and to collect the imagery used to model the topography has theoretical vertical and horizontal accuracies of 5 meters. See the bathymetry and imagery datasets and metadata in the larger work citation for more details.
Logical_Consistency_Report:
This file represents the merged 1 meter single beam echo-sounder bathymetry data and digital surface model created from imagery collected by Peter Traykovski or WHOI. These data were combined with 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.

Process_Step:
Process_Description:
The 25 cm Digital Surface Model (DSM) 2020015FA_Truro_DSM_25cm.tif and the 1 m bathymetry grid 2020015FA_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 are combined with the interpolation method regularizedata3d (bicubic interpolation) with 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. Combined grid is 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 ROI to 0. The boundary is determined by specifiying the polygon verticies as the regularizedata3D outputs (x,y,z) from the previous step and prevents extrapolation beyong the tracklines of the Bathy and DSM extent.
3. The final merged GeoTIFF is created using the GRIDobj tool in the TopoToolbox (Schwanghart and Scherler, 2014) which uses the interpolated grid from Step 1 and the mask from step 2 to create the final output. The GeoTIFF is output in NAD83(2011)/UTM Zone 19N in the vertical datum NAVD88 in meters.
