Description:

Abstract:

The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) project collects aerial imagery along coastal swaths, in response to storm events, with optimized endlap/sidelap and precise position information to create high-resolution orthomosaics, three-dimensional (3D) point clouds, and digital elevation/surface models (DEMs/DSMs) using Structure-from-Motion (SfM) photogrammetry methods. These products are valuable for measuring topographic and landscape change, and for understanding coastal vulnerability and response to disturbance events. A nadir (vertical) aerial imagery survey was conducted from Cape Lookout, North Carolina to the Virginia-North Carolina border on August 30th and September 2, 2019, to document pre-storm conditions in preparation for the passing of Hurricane Dorian (U.S. landfall was on September 6). The observations along the coastline cover an approximately 275-kilometer (km) long by 300 to 700-meter (m) wide swath of coastline and encompass both highly developed towns as well as natural undeveloped areas, including the federal lands of Cape Lookout National Seashore and Cape Hatteras National Seashore. Low altitude (300 meters above ground level) digital aerial imagery were acquired from a manned, fixed-wing aircraft using a Sony A7R 36 Megapixel digital camera, along with precise aircraft navigation Global Navigation Satellite System (GNSS) data. Data were collected in shore-parallel lines, flying at approximately 50 meters per second (m/s) and capturing true color imagery at 1 Hertz (Hz), resulting in image footprints with approximately 75-80% endlap, 60-70% sidelap, and a 5.3-centimeter (cm) ground sample distance (GSD). The precise time of each image capture (flash event) was recorded, and the corresponding aircraft position was computed during post-processing of the GNSS data; precise image positions can then be determined by accounting for the lever arm offsets between the aircraft GNSS antenna and the camera lens. Position data, provided as latitude/longitude/ellipsoid height, is referenced to the North American Datum of 1983 (NAD83(2011)).

Purpose:

These 24,072 aerial images were collected over two non-consecutive days along the coast of the Outer Banks, North Carolina, with sufficient resolution and endlap/sidelap to produce Structure-from-Motion (SfM) photogrammetry products to observe the baseline conditions of the coast before any impacts due to Hurricane Dorian.

Supplemental_Information:

These data were collected by the USGS Coastal and Marine Hazards and Resources Program under the USGS field activity number (FAN) 2019-310-CNT, and the associated field activity web page contains additional information regarding the field activity: https://cmgds.marine.usgs.gov/fan_info.php?fan=2019-310-CNT. To guarantee coverage of the entire survey area with good lighting conditions, aerial imagery was collected over multiple days; acquisition was timed to coincide with low tide along the beach areas to ensure the maximum shoreline extent was captured. Bounding coordinates for the aerial survey are derived from the overall flight path and are not necessarily representative of the imagery coverage.

Attribute_Accuracy:

Attribute_Accuracy_Report:

The accuracy of the position data is based on the accuracy and precision of the GNSS equipment and camera timing, number and length of baselines and atmospheric conditions. Note that the positions in the image EXIF headers are aircraft GNSS antenna positions and are limited to six decimal places, whereas the positions in the external navigation file are accurate to ten decimal places and are therefore highly recommended for use in SfM processing to produce the highest quality derived products.

Logical_Consistency_Report: All data fall within expected ranges.
Completeness_Report:

This dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the entire metadata record carefully for additional details.

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Positions provided in the aircraft navigation file (2019-08_NC_AircraftPositions.txt) have an estimated 2-sigma horizontal accuracy of 10 cm. The accuracy of the positions in the image EXIF headers are reduced due to field size limitations for storing latitude/longitude.

Positions provided in the aircraft navigation file (2019-08_NC_AircraftPositions.txt) have an estimated 2-sigma vertical accuracy of 15 cm.

Process_Description:

IMAGE ACQUISITION C. W. Wright Consulting used a Sony A7R 36 Megapixel digital camera aboard a Piper P28A aircraft to conduct a nadir (vertical) aerial imagery survey from Cape Lookout, North Carolina, to the Virginia-North Carolina border on August 30th and September 2nd, 2019, to document pre-storm conditions in preparation for the passing of Hurricane Dorian. Data were collected to facilitate SfM processing (Westoby and others, 2012) in shore-parallel lines, flying at approximately 50 m/s and capturing true color imagery at 1 Hz, resulting in image footprints with approximately 75-80% endlap, 60-70% sidelap, and 5.3-cm GSD. A total of 24,072 raw (ARW) images, raw dual-frequency carrier phase GNSS data and photo event time data were delivered to the USGS St. Petersburg Coastal and Marine Science Center.

Process_Step:

Process_Description:

AIRCRAFT NAVIGATION PROCESSING Raw GNSS data received by the antenna mounted atop the aircraft were recorded at 1 Hz by a dual-frequency survey-grade GNSS receiver, which was post-processed and differentially corrected with no fewer than 5 continuously operating reference stations (CORS) using Novatel's GrafNav software (v. 8.80) to produce 1-Hz aircraft trajectories. The aircraft trajectories, in combination with precisely recorded image capture (flash event) times, are used to generate aircraft GNSS antenna positions at the moment of each image capture (2019-08_NC_AircraftPositions.txt). The positions in the aircraft navigation file represent the position of the aircraft GNSS antenna, not the position of the camera or features photographed. To determine actual image positions, photogrammetric software such as Agisoft Metashape can be used to apply the lever arm offsets (in the camera frame of reference) from the GNSS antenna reference point to the camera lens, which are 0.1 m, -0.15 m, and 1.25 m, in the x, y, and z directions respectively; see Over and others (2021) for details.

Image file names represent capture date, time stamp, and ancillary data, using the following convention: yyyy-mmdd-hhmmss-DSCnnnnn-N7251F.jpg where yyyy_mmdd represents the year (yyyy), month (mm) and day (dd) of capture; hhmmss is the time of capture as hours (hh), minutes (mm), seconds(ss) in Universal Coordinated Time (UTC); DSCnnnnn represents a sequential image ID generated by the camera; and N7251F is the tail number of the aircraft used for acquisition.

IMAGE EXIF & SORTING Georeferencing, copyright, and other relevant information was added to the EXIF header of each photo using Phil Harvey’s ExifTool (v. 11.88). To extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 11.88): exiftool -csv -f -filename -GPSDateStamp -GPSTimeStamp -GPSLongitude -GPSLatitude -n -Artist -Credit -comment -keywords -Caption -Copyright -CopyrightNotice -Caption-Abstract -ImageDescription directoryname/*.jpg > out.csv The -csv flag writes the information out in a comma-delimited format. The -n option formats the latitude and longitude as signed decimal degrees. Images are sorted by latitude and contained within zip files according to 3-minute latitude segments of the coast (labeled based on the southern latitude boundary in degrees (DD) and minutes (mm) North (N), and further subdivided (labeled as -a/b/c) as needed to limit the overall file size.
