Abstract:
These data map in high detail surficial cross-sections of North Core Banks, a barrier island in Cape Lookout National Seashore, NC, in October 2022. U.S. Geological Survey field efforts are part of an interagency agreement with the National Park Service to monitor the recovery of the island from Hurricanes Florence (2018) and Dorian (2019). Three sites of outwash, overwash, and pond formation were targeted for extensive vegetation ground-truthing, sediment samples, bathymetric mapping with a remote-controlled surface vehicle, and uncrewed aerial systems (UAS) flights to collect multispectral imagery. Five semi-permanent ground control points were also installed and surveyed to act as control for additional aerial imagery collected via plane. UAS imagery were processed in Agisoft Metashape (v. 1.8.1) with surveyed temporary ground control points to produce calibrated multispectral (red, blue, green, red edge, near infrared, and panchromatic) orthoimages and digital surface models.
Purpose:
Multispectral and true-color images were collected with appropriate resolution and overlap to permit high-quality photogrammetry and generation of reflectance imagery and multispectral indices, which can be used for identification of vegetation and other groundcover.
Supplemental_Information:

Attribute_Accuracy_Report:
The first sensor, a MicaSense Altum-PT, acquired 3.2 (RBG, NIR, RE) and 12.4 (panchromatic) megapixel photos, with file sizes generally between 6 and 24 MB on disc, depending on image complexity and band. All images were tagged with an internal GPS, this provides xyz and roll, pitch, and yaw positional information and accuracies. These values are accessible by reading the exif information; see below for instructions on how to access them. Band information and camera settings are also available through this method. The accuracy of the multispectral sensors were determined using a MicaSense Reflectance Panel and two calibrated reflective tarps that were visible in the imagery. The second sensor, a Ricoh GRII, acquired 3.2 megapixel photos, with file sizes generally around 6 MB on disc. Images that aligned in the Agisoft Metashape projects are geotagged with reconstructed locations (note that this means some images provided that did not align do not have location information). See the orthoimage metadata for more information, available in the larger work citation.
Logical_Consistency_Report:
Six flights were flown in total for the field activity. Each flight produced images from the Altum-PT and Ricoh GRII. Images were renamed to the format 2022034FA_f##aPT_YYYYMMDDTHHMMSSZ_originalFilename, where 2022034FA is the field activity, f## is the flight number, aPT stands for the Altum-PT sensor and r03 is the Ricoh GRII ID, then the date and time (UTC) separated by a T and Z, respectively; and then the original file name where the following suffixes of each file correspond to the following bands: _1 is the blue band; _2 is the green band; _3 is the red band; _4 is the near infrared (NIR) band; _5 is the red edge band; and _6 is the panchromatic band. Ricoh images do not have a band suffix. The coordinate reference system embedded in the Altum-PT image headers is WGS84 + EGM96 height. Additional transformed coordinate systems, using VDatum (https://vdatum.noaa.gov/vdatumweb/), are provided in the 2022034FA_NCB_Altum-PT_ImageLocations.csv and 2022034FA_NCB_Ricoh_ImageLocations.csv in NAD83(2011) and in UTM18N + NAVD88 (geoid 18) for ease of use. Images were zipped to reduce download size (less than 10 GB per zip folder), zip folders are named using the convention 2022034FA_NCB_Altum-PT_f##a-c, where ## is the flight number and folders of the same flight are distinguished with an a, b, or c.
Completeness_Report:
Once turned on the sensors triggered every 2 seconds. The Altum-PT took 7 individual images per band each time, distinguished by a suffix of _1 to _7. All images with a suffix of _7 were removed from this dataset; these are the thermal (LWIR) images that did not have a calibration check source nor are relevant to the goals of the field activity. One to five sets of the MicaSense Calibration panel at the beginning and end of each flight were kept, but additional sets of images were removed for redundancy and space. Images at take-off and landing that contained no panel were also removed for space. All of these removed images can account for the non-consecutive original file names and results in a total of 15,176 Altum-PT images and 2,068 Ricoh GRII images that are provided in zipped files by flight number. Not all Ricoh photos included have location information.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Though the images do not represent spatial data, the latitude and longitude are embedded in the photos and available in the EXIF header of each image and also in UTM coordinates provided in the files (2022034FA_NCB_Altum-PT_ImageLocations.csv and 2022034FA_NCB_Ricoh_ImageLocations.csv). The Altum-PT location information was acquired from an internal GPS receiver in the Altum-PT and has an average horizontal accuracy of 1 meter; individual image xy accuracies are embedded in the exif information. Ricoh location information is derived from Agisoft Metashape reconstructed locations and are likely accurate to within 5 meters. Accuracies may be lower than reported when the UAS system executed tight turns near the edges of the flight paths and when landing and taking off. It is recommended to use the ground control points provided in the larger work citation for georeferencing.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Though the images do not represent spatial data, the altitude of each image is embedded in the photos and available in the EXIF header of each image. The vertical position values are also provided in the files 2022034FA_NCB_Altum-PT_ImageLocations.csv and 2022034FA_NCB_Ricoh_ImageLocations.csv. The Altum-PT altitude information was acquired from an internal GPS receiver and has an average vertical accuracy of 1.5 meters; individual image z accuracies are embedded in the exif information. Accuracies may be lower than reported (up to 20 meters different) when the UAS system executed tight turns near the edges of the flight paths and when landing and taking off. Ricoh location information is derived from Agisoft Metashape reconstructed locations and are likely accurate to within 5 meters. It is recommended to use the ground control points provided in the larger work citation for georeferencing.

Process_Step:
Process_Description:
The Altum-PT and Ricoh GRII sensors were attached to the bottom of the DJI Matrice 600 pointing nadir. The Altum-PT was wired to a downwelling light sensor and GPS attached to the top of the UAS. A MicaSense reflection calibration panel was placed in view of the Altum-PT before and after take-off so the sensor captured the panel in the images. For flight, both sensors were set to record images at 2-second intervals, activated before takeoff and deactivated after landing. Flights were flown along pre-planned lines and lasted the duration of the UAS battery life (approximately 15 minutes) or until the flight was completed or aborted. The sensors were not mounted on a gimbal so capture scenes were dependent on the attitude of the UAS. The Altum-PT received power from a connection to the UAS. The downwelling light sensor measured ambient light for each of the spectral bands captured by the camera. For each camera shutter trigger, camera settings (focal length, ISO, etc), spectral irradiance, roll, pitch, yaw, gain, exposure time, and GPS position data were automatically incorporated into the Exif data for each image.
Process_Date: 20221020
Process_Step:
Process_Description:
A new reformatted SD card was used for each flight. The images acquired with the sensors were geotagged and processed to add additional information required by the USGS to the EXIF headers using ExifTools (https://exiftool.org/, version: 12.06), and the files were renamed to a unique identifier using Namexif (http://www.digicamsoft.com/softnamexif.html, version 2.1) to avoid any possibility of duplicate names. These steps are described here. (.*jpg was used for Ricoh images) 1. ExifTools was used to tag each photo with the following headers: Credit, Copyright, UsageTerms, ImageDescription, and Artist; where the name of each file and the header information was stored in a csv file and written to each image with the command:' exiftool -csv="C:\directory\name\EXIF.csv" C:\directory\name\of\photos *.tif ' Additional keywords were added with the following command in the directory with all the photographs: exiftool -keywords="UAS imagery" -keywords="North Core Banks, Cape Lookout National Seashore" -keywords="North Carolina" -keywords="2022034FA" -keywords="USGS" -overwrite_original *.tif To read out the photo information to a csv when in the directory with the photos the command is: exiftool -csv *.tif > directory/name/allheaders_out.csv 2. All the images were renamed with Namexif (https://us.digicamsoft.com/softnamexif.html v 2.2 accessed April 2020) to ensure unique filenames and compliance with the USGS Coastal and Marine Hazards and Resources Program's best practices for image naming convention. Images were renamed with the field survey ID prefix; flight number, and ID that distinguishes USGS cameras by make/camera number, the image acquisition date, coordinated universal time (UTC) in ISO8601 format, and a suffix with the original image name. For example, image name '2022034FA_f01aPT_20221020T165822Z_IMG_####_#', 2022034FA is the survey ID, f01 is the flight number, aPT is the camera make Altum-PT and r03 is the Ricoh GRII ID, and 20221020 is the UTC date in the format YYYYMMDD. A 'T' is used to separate UTC date from UTC time in format HHMMSS followed by a Z, and IMG_####_#.tif is the original raw photo name appended to the end of the new filename.

Overview_Description:
Entity_and_Attribute_Overview:
The attributes cover both image location files, which have the same headers. The Altum-PT images are 16-bit, RGB-RE-NIR and panchromatic, TIFF images. Each image is a single wavelength so will appear grayscale when viewed independently. The image location files contain the positions for all flights, though only one band position is provided as all six bands per time of capture have the same location. The Altum-PT image location headers GPSLatitude, GPSLongitude, and GPSAltitude, which are embedded in the images, are the original MicaSense GPS positions in WGS 84 + EGM 96 height, the image locations file is provided for ease of use in the commonly used USGS reference systems. The Ricoh GRII images are JPEGs and have been geotagged with the reconstructed locations in NAD83(2011) and the reference ellipsoid. But note that all of these positions have an overall poor accuracy and it is recommended that the ground control points available in the larger work citation are used to georeferenced any photogrammetry products rather than the using the image positions.
