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 Virginia Beach, Virginia between August 5th, 2020 and August 8th, 2020, to document post-storm conditions after the passage of Hurricane Isaias on August 3, 2020. The observations along the coastline cover an approximately 325-kilometer-long by 300 to 700-meter-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 with a manned, fixed-wing aircraft using the "Precision Airborne Camera (PAC)" System (version 2). The PAC system is operated by C.W. Wright and consists of a mounted fixed-lens digital camera, along with a custom integrated survey-grade Global Navigation Satellite System (GNSS) receiver. 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, which are provided in the PAC System metadata (Kranenburg and others, 2023, https://cmgds.marine.usgs.gov/data-services/rscc/PrecisionAirborneCameraSystem). Position data, provided as latitude/longitude/ellipsoid height, is referenced to the North American Datum of 1983 National Spatial Reference System 2011 (NAD83(2011)) coordinate system. Purpose: These 18,442 aerial images were collected along the coast of the Outer Banks, North Carolina, with sufficient resolution and endlap/sidelap to produce SfM photogrammetry products to capture the state of the coast days after Hurricane Isaias's landfall. Supplemental_Information: Each data collection is recorded in the USGS Coastal and Marine Hazards Resources Program (CMHRP) Coastal and Marine Geoscience Data System (CMGDS) field activity database and is assigned a Field Activity Number (FAN). Additional information about the field activity from which these data were derived is available online at: https://cmgds.marine.usgs.gov/fan_info.php?fan=2020-306-CNT. 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. This data collection is published under the Precision Airborne Camera System data collection platform (DCP) within the RSCC Simple Data Distribution Service. This data service is structured in a folder (directory) hierarchy with subfolders corresponding to individual DCPs or groups of DCPs, which in turn contain folders with products grouped by collection effort.

Note that the positions in the imagery 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. No effort is made to optimize exposure through post-processing. These data represent raw imagery, as collected, and subsequently used in SfM photogrammetric processing workflows. Logical_Consistency_Report: All data fall within expected ranges. RGB (red, green, blue) values are 8-bits per band, generally not saturated or underexposed. In a few cases of high or low light conditions, some imagery may be over or underexposed. GNSS values are checked for consistency and outliers. Bad data are discarded, and missing data are interpolated. 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 and to examine the imagery header metadata for additional details. Some images may lack position information in their imagery headers resulting from a momentary disruption in GNSS signals but in most cases, interpolated positions based on GNSS timestamps were applied to these images. The beginning and end of the survey were reviewed to cull extraneous images such as camera testing or inadvertently triggered image. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal positions provided are in the aircraft navigation file (NC_OBX_20200805-20200808_postIsaias_AircraftPositions.txt) and have an estimated 2-sigma horizontal accuracy of 10 cm. The accuracy of the positions in the imagery headers were reduced due to field size limitations for storing latitude/longitude. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical positions are provided in the aircraft navigation file (NC_OBX_20200805-20200808_postIsaias_AircraftPositions.txt) and have an estimated 2-sigma vertical accuracy of 15 cm. Lineage: Process_Step: Process_Description: IMAGE & POSITION ACQUISITION -- C. W. Wright Consulting used the Precision Airborne Camera (PAC) system, equipped with a Sony A7R 36 Megapixel digital camera aboard a Piper P28A aircraft to conduct a nadir (vertical) aerial imagery survey from Cape Lookout to Virginia Beach, Virginia between August 5th, 2020 and August 8th, 2020, to document post-storm conditions after the passage of Hurricane Isaias on August 3, 2020. Data were collected to facilitate SfM processing (Westoby and others, 2012) in shore-parallel lines, flying at approximately 50 meters per second (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. 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 (SPCMSC).

The following pattern string is used in the batch renaming tool to rename the images from their raw name format (DSCnnnnn) to the naming convention defined above: $E36868(%Y-%m%d-%H%M%S)-$N-N7251F.

A multi-page contact sheet of images was created to allow quick review ensuring that (a) conversion was successful with no corrupted imagery, and (b) "extra" imagery not capturing the intended view was culled. If corrupted converted images were found, imagery is re-converted until a collection of valid images remains. Note that in some cases, water-only images may be retained if there were visible or potentially visible bathymetric features, aquatic vegetation, and/or objects in the scene that may be useful for future data applications.

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 (NC_OBX_20200805-20200808_postIsaias_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 more details.
