U.S Geological Survey personnel conducted field surveys to collect topographic data using global navigation satellite systems (GNSS) at all three beaches. In addition, at Nauset Light Beach, an uncrewed aerial system (UAS) was used to collect images with a Ricoh GRII camera for use in structure from motion photogrammetry. High-precision GNSS targets (AeroPoints) were used as ground control points (GCPs) for the UAS photogrammetry. Agisoft Metashape (v. 2.0.1) software was used to create a digital surface model and an orthomosaic from the collected imagery and GCPs. Photos were taken with smartphones for environmental context. This work was conducted under National Park Service Research Permit CACO-2020-SCI-0021. Purpose: The ground control points (GCPs) are for georeferencing the structure from motion (SfM) project and the GPS data are to provide topographic context for the pressure sensors of WHCMSC Field Activity 2023-023-FA. Supplemental_Information: For more information about the WHCMSC Field Activity, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2023-022-FA. These data are also related to USGS field activity 2023-023-FA, which collected pressure-sensor measurements at these three beaches.

Logical_Consistency_Report: The file contains USGS field activity 2023-022-FA navigation data: ground control points (AeroPoints) deployed on September 14 and 20 for use in tandem with the aerial imagery and GPS points taken at each beach before and after the storm. Completeness_Report: There are a total of 8 AeroPoints, 3 were deployed for the pre storm flights and 5 were deployed for the post storm flights. GPS points are labeled by date and location. Coordinates for all data are provided in geographic and projected reference systems. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: AeroPoint targets have theoretical sub 1 cm horizontal absolute accuracy. RTK and CORS data have a 2 cm horizontal accuracy based on a comparison of measurements taken of known reference marks (RM). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: AeroPoint targets have theoretical sub 1 cm vertical absolute accuracy. RTK and CORS data have a 2 cm vertical accuracy based on a comparison of measurements taken of known reference marks (RM). Lineage: Process_Step: Process_Description: The ground control points were processed with the following steps: 1. AeroPoints were deployed across the survey area. AeroPoints were left on for at least 1 hour and up to 2 hours to collect data. 2. Once connected to Wifi, the AeroPoint data were uploaded and run through a Propeller post-processing kinematic algorithm. The data were exported the horizontal datum NAD83(2011) to produce latitude, longitude, and ellipsoid heights, and then UTM Zone 19N and NAVD88 using GEOID 18 were used to produce UTM coordinates and orthometric heights. These were exported to a CSV file 2023022FA_HxLee_NBL_Aeropoints.csv Process_Date: 202309 Process_Step: Process_Description: The GPS data were collected and processed as follows. At Head of the Meadow and Marconi beaches a base station was setup on a known reference mark and RTK corrections were broadcast to a rover. At Nauset Light Beach instead of a base station a wifi connection was used to connect the rover to the Massachusetts CORS network. The rover was then used at each beach to take points along cross-shore transects before and after Hurricane Lee and on the top of the posts where pressure sensors were attached. GPS data was exported from the rover in the horizontal datum NAD83(2011) to produce latitude, longitude, and ellipsoid heights, and then UTM Zone 19N and NAVD88 using geoid 18 were used to produce UTM coordinates and orthometric heights. These were exported to a CSV file 2023022FA_HxLee_GPSdata.csv. Process_Date: 202309 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Jin-Si R.
