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: Ground control points for georeferencing the aerial imagery.

Logical_Consistency_Report: The file contains USGS field activity 2021-014-FA navigation data: ground control points (AeroPoints) deployed on February 4 for use in tandem with the aerial imagery. Completeness_Report: There are a total of 10 usable ground control points. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: AeroPoint targets have theoretical 1 cm horizontal absolute accuracy. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: AeroPoint targets have theoretical 1 cm vertical absolute accuracy. Lineage: Process_Step: Process_Description: The ground control points (AeroPoints) were processed with the following steps: 1. Ten AeroPoints were deployed evenly spaced across the survey area and left on for ~2 hours to collect GNSS data. 2. Once connected to Wifi, the AeroPoint data were uploaded and run through a post-processing kinematic algorithm. The data were exported with X,Y, and Z variances in the horizontal datum NAD83(2011) to produce latitude, longitude, and ellipsoid heights, and then GEOID 18 was used to produce orthometric heights. These are exported to a CSV file named 2021014FA_Truro_nav_AeroPoints.csv. See completeness report for more details.
