Description:
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:
The navigation and point data can be used to ground truth the digital elevation model in the larger work and be used in the external calibration of the Coastcam.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Positions and elevations are verified by external sources, ex: OPUS Solutions for the receivers, see Positional_Accuracy section.
Logical_Consistency_Report:
The files contain real-time kinematic satellite (RTK-GNSS) navigation and elevation data collected on foot using two receivers (Spectra Precision SP80 GNSS) corrected to a base station set up in the parking lot on March 04 and ground control points (AeroPoints) deployed on March 06 during USGS field activity 2020-015-FA.
Completeness_Report:
Points from the foot survey were edited for quality control and some points were removed due to obvious errors (such as lack of attribute label or recording point when rover pole was on the ground), this can explain non-consecutive Point Labels. Users are advised to read the rest of the metadata record carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Calculated RTK horizontal positions have an accuracy of +/- 30 centimeters. AeroPoint targets have theoretical 1 cm horizontal absolute accuracy.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical accuracy of the calculated vertical elevation above datum is +/- 1 centimeter. AeroPoint targets have a theoretical 5 cm vertical absolute accuracy.

Process_Step:
Process_Description:
The RTK-GNSS data was collected and processed in the following manner:
1. A base station was set up in the parking lot on an established benchmark in the Head of the Meadow Parking lot and left on for 7 hours. An OPUS solution was calculated for the Benchmark and two Reference Marks.
2. The two Spectra receivers were localized to the base station. The height of rover #2 is 1.9820 m, rover #3 is 1.9819 and both were collecting RTK data in NAD83(2011) Zone 19N using Geoid 12B.
3. Rovers were then walked along the beach along nine pre-described transects perpendicular to the shoreline with one shoreline parallel transect along the berm taking points at least every 1-2 meters. Points were also taken at the top of the bluff and at the base of the bluff to characterize the slope.
4. In order to calibrate the CoastCams looking down from the bluff to the beach, five plywood checkerboard targets were placed propped up on the beach facing towards the CoastCam. These were measured with the rovers at the intersection of the sand and the middle of the target. The same targets were moved five times, so the same attribute label may have a different time, elevation, etc.
5. The RTK data is exported as CSV files using SurvCE (http://survce.com/home).
6. Rover data was manually redistributed into two CSV files. The first, 2020015FA_Truro_nav_transects.csv contains all the data collected to ground truth the survey site; transects, bluff points, and the benchmark measurements. The second, 2020015FA_Truro_nav_CoastCamtargets.csv, contains the positions of the plywood targets and the two CoastCam video cameras on the bluff.

Process_Description:
The ground control points (AeroPoints) targets were processed with the following steps:
1. Eleven AeroPoints were deployed evenly spaced across the survey area and left on for a minimum of 3 hours to collect GNSS data.
2. Once connected to Wifi, the AeroPoint data is uploaded and is run through a post-processing kinematic algorithm and is exported with X,Y, and Z variances in the horizontal datum NAD83(2011) to produce latitude, longitude, and ellipsoid heights and then the GEOID 12B was used to produce orthometric heights. These are exported to a CSV file named 2020015FA_Truro_AeroPoints.

Entity_and_Attribute_Overview:
These attribute definitions describe each column of information in the CSV files with the exception of additional information in the last three columns of the 2020015FA_Truro_nav_AeroPoints.csv. Those columns contain the X, Y, and Z variance, in mm, of the AeroPoint position. Null values (999) indicate the attribute was not calculated or applicable. Trailing and leading zeros may not appear in the csv and so some values may not display as many significant digits as described.
