Description:
Abstract:
The data in this release map the beach and nearshore environment at Marconi Beach in Wellfleet, MA and provide updated environmental context for the 2021 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is related to the field activity 2022-014-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 CoastCam CACO-02, which are two video cameras aimed at the beach. In March 2022, U.S Geological Survey and Woods Hole Oceanographic Institute (WHOI) scientists conducted field surveys to map the CoastCam field of view. 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 imagery, 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 setup and is meant to document change over time.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
No official QC test was performed, but all elevation values are internally consistent in relation to previous surveys (see cross-reference). See the bathymetry and topography datasets and metadata in the larger work citation for more details on the components that make up the topobathy grid.
Logical_Consistency_Report:
Grid values match the individual bathymetry and topography datasets in the larger work citation. The resolution of the topography was lowered in the topobathy grid.
Completeness_Report:
This product represents the full extent of the topography and bathymetry available in the larger work citation.

Process_Step:
Process_Description:
The 25 cm Digital Surface Model (DSM) 2022014FA_Marconi_DSM_25cm.tif and the 1 m bathymetry grid 2022014FA_Marconi_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 (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 exported in NAD83(2011)/UTM Zone 19N with the vertical datum NAVD88 in meters.
