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.
