Title:
Landscape and contextual field work photos, with locations, taken in September 2023, pre and post Hurricane Lee at Head of the Meadow, Marconi, and Nauset Light beaches in CACO, MA
Abstract:
The data in this release map Marconi Beach, Head of the Meadow Beach, and Nauset Light Beach, in Cape Cod National Seashore (CACO), Massachusetts, before and after Hurricane Lee in September 2023. U.S Geological Survey personnel conducted field surveys to collect topographic data using global navigation satellite systems (GNSS) at all three beaches. In addition, at Nauset Light Beach, an uncrewed aerial system (UAS) was used to collect images with a Ricoh GRII camera for use in structure from motion photogrammetry. High-precision GNSS targets (AeroPoints) were used as ground control points (GCPs) for the UAS photogrammetry. Agisoft Metashape (v. 2.0.1) software was used to create a digital surface model and an orthomosaic from the collected imagery and GCPs. Photos were taken with smartphones for environmental context. This work was conducted under National Park Service Research Permit CACO-2020-SCI-0021.

Why was the data set created?

Images observe equipment, ground conditions, and change over time before, during, and after Hurricane Lee.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: Sep-2023 (process 1 of 1)
    These images were taken by Chris Sherwood with a Pixel smartphone. Images were mostly taken around the areas pressure sensors were deployed (Field Activity 2023-023-FA) before, during, and after the storm. A CSV was created to provide captions, locations, and dates for each photo. The images 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 additional information. These steps are described here. For more information on the EXIF tags here and automatically populated by the camera see https://exiftool.org/TagNames/EXIF.html 1. ExifTools was used to tag each photo with the following tags: Credit, Copyright, UsageTerms, ImageDescription, Artist, XMP:UsageTerms, XMP:AttributionURL, GPSLatitudeRef, GPSLongitudeRef, GPSAreaInfo, GPSMapDatum, GPSLatitude, GPSLongitude, and GPSAltitude stored in a CSV file with the command:' exiftool -csv="C:\directory\name\Geotags_EXIF.csv" C:\directory\name\of\photos *.jpg The first row of the CSV are the tag names; the first column is SourceName (image names). To read out the photo information to a CSV when in the directory with the photos the command is: exiftool -csv *.jpg > allheaders_out.csv 2. Image names follow the format '2023022FA_PXL_20230914T134646Z.jpg', where 2023022FA is the field activity ID, PXL is for Pixel smartphone, and 20230914 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. The original raw photo name is not appended to the end of the new filename because it was a repeat of PXL and the date and time. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Photo locations taken with a smartphone are less accurate and have not been QA/QC’d.
  2. How accurate are the geographic locations?
    Though the images do not represent spatial data, the spatial information is embedded in the photo and available in the EXIF header of each image, which is provided in the imagery information file (2023022FA_HxLee_imageinformation.csv). The accuracy of the estimated positions is 1 to 5 meters and is based on J. Over's knowledge of the area as the photos were not automatically geotagged by the phone.
  3. How accurate are the heights or depths?
    Though the images do not represent spatial data, the spatial information is embedded in the photo and available in the EXIF header of each image, which is provided in the imagery information file (2023022FA_HxLee_imageinformation.csv). The accuracy of the estimated positions is 1 to 2 meters and is based on J. Over's knowledge of the area and elevation data of the area, as the photos were not automatically geotagged by the phone..
  4. Where are the gaps in the data? What is missing?
    Photos are a general representation of the field activity, for more photos or information regarding the response to Hurricane Lee reach out to whsc_data_contact@usgs.gov
  5. How consistent are the relationships among the observations, including topology?
    Each photo has a location and contextual information.
