Description:
Abstract:
The data in this part of the release provide the location information of the temporary ground control points placed on the beach at the USGS DUring Nearshore Event eXperiment (DUNEX) site on Pea Island National Wildlife Refuge, NC. DUNEX is a multi-agency, academic, and non-governmental organization collaborative community experiment designed to study nearshore coastal processes during storm events. USGS participation in DUNEX will contribute new measurements and models that will increase our understanding of storm impacts to coastal environments, including hazards to humans and infrastructure and changes in landscape and natural habitats. Collected data are part of field activity 2021-029-FA. During September and October 2021, USGS and Woods Hole Oceanographic Institute (WHOI) scientists conducted multiple field surveys to collect an elevation time series. Ground control point location data were collected using a real time kinematic – satellite navigation system (RTK-GNSS) receiver. Images of the beach for use in structure from motion were taken with a camera attached to a helium filled balloon-kite (Helikite). Agisoft Metashape (v. 1.8.1) was used to create orthomosaics and digital surface models (DSMs) with the collected imagery and ground control points.
Purpose:
Ground control points (GCPs) are for georeferencing the aerial imagery.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Positions and elevations are produced by either a Spectra Precision (SP)80 Base Station and Rover or Rover and North Carolina CORS Network. AeroPoint post processed network positions and Rover positions were all within 2 cm in the XYZ directions as a QC check, but for consistency all positions provided are from the SP80.
Logical_Consistency_Report:
The file contains USGS field activity 2021-029-FA ground control points.
Completeness_Report:
GCPs are not always visible in associated imagery or are visible but do not have location information – as much information as is available is provided.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The SP80 RTK systems used to collect location data have a theoretical horizontal accuracy of 2 cm on any single point, but QC and repeat occupations of the same spot suggest slightly higher uncertainties up to 5-10 cm including user error.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The SP80 RTK systems used to collect location data have a theoretical vertical accuracy of 1 cm on any single point, but QC and repeat occupations of the same spot suggest slightly higher uncertainties up to 5-10 cm including user error.
Lineage:
Process_Step:
Process_Description:
Over the field activity, the SP80 equipment was used to take the location information of ground control points and equipment installed at the field site. At the end of the field activity all GPS points were corrected to the OPUS solution averages of the reference marks (see larger citation GPS data) by shifting the XYZ in Carlson SurvCE v. 6.08 (http://survce.com/home, accessed August, 2021).
Ground control points for the Helikite surveys were either black and white square plastic tarps with a number on them or AeroPoint yellow and black targets that were replaced every survey – a random letter was used for each survey to distinguish between surveys that used the same GCPs. All GCPs were measured at the center of the tarp or target with the SP80 pole and equipment. Process date reflects the beginning of the events. Data processing ended in 2021-11.
