These data were collected as part of field activity 2021-022-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. Starting in February and ending in March 2021, U.S Geological Survey and Woods Hole Oceanographic Institute (WHOI) scientists conducted field surveys to collect position and orientation information for the CoastCam cameras and map the field of view. Two new reference marks were established in the Marconi Beach parking area to establish ground control for future surveys. 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. Grain-size analysis was performed on sediment samples collected with a spade along multiple profiles from the bluff base to the intertidal zone. 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) and 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 survey vehicle. 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: May be used as an elevation dataset for use by the public, researchers, and others to observe ground conditions and change over time of the bluffs, dunes, beach, and nearshore of Marconi Beach in view of the CoastCam setup. Supplemental_Information: This topobathymetric grid represents approximately 0.962 square kilometers. The GeoTIFF is not cloud optimized.

Lineage: Process_Step: Process_Description: The 25 cm Digital Surface Model (DSM) 2021022FA_Marconi_topography_25cm.tif and the 1 m bathymetry grid 2021022FA_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 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 specifying the polygon vertices as the regularizedata3D outputs (x,y,z) from the previous step and prevents extrapolation beyond 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 horizontal coordinate system in the vertical datum NAVD88 with elevations and depths in meters. Schwanghart, W., Scherler, D.
