Title:
Winter 2016, part A, coastal oblique aerial photographs collected from the South Carolina/North Carolina border to Assateague Island, Virginia, February 18-19, 2016
Abstract:
The U.S. Geological Survey (USGS) conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms. On February 18-19, 2016, the USGS conducted an oblique aerial photographic survey from the South Carolina/North Carolina border to Assateague Island, Virginia, aboard a Cessna 182 aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore (fig. 2, http://pubs.usgs.gov/ds/1029/html/ds1029_fig2.html). This mission was conducted to collect data for assessing incremental changes in the beach and nearshore area since the last survey, flown in October 2015 (http://cmgds.marine.usgs.gov/fan_info.php?fan=2015-338-FA) (Morgan, 2016, [http://dx.doi.org/10.3133/ds/995]), and the data can be used to assess future coastal change. The photographs provided are Joint Photographic Experts Group (JPEG) images. The photograph locations are estimates of the aircraft’s positions and do not indicate the location of the feature in the images (See the Navigation Data page, http://pubs.usgs.gov/ds/1029/html/ds1029_nav.html). These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. ExifTool was used to add the following to the header of each photo: time of collection, Global Positioning System (GPS) latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet. All image times are recorded in Coordinated Universal Time (UTC). Table 1 (http://pubs.usgs.gov/ds/1029/html/ds1029_table.html) provides detailed information about the assigned location, name, date, and time the photograph was taken along with links to the photograph. In addition to the photographs, a Google Earth Keyhole Markup Language (KML) file is provided and can be used to view the images by clicking on the marker and then clicking on either the thumbnail or the link above the thumbnail. The KML files were created using the photographic navigation files. Note: A KML number was assigned to each photograph to assist users in navigating the Google Earth file. These numbers correspond to the site labels in Google Earth.
Supplemental_Information:
Part B of this survey was conducted on March 8-9, 2016 (http://dx.doi.org/10.3133/ds1030). For a summary of field activity 2016-316-FA please see http://cmgds.marine.usgs.gov/fan_info.php?fan=2016-316-FA. Bounding coordinates for the oblique aerial survey are derived from the overall flight path found in the raw GPS data. Ancillary files included in this publication are ds1029_2016-316-FA-A.csv, ds1029_2016-316-FA_0218_gpsmap696.txt, and ds1029_2016-316-FA-A.kml, in addition to the digital oblique aerial image files.

    Image Acquisition: Images were taken with a Nikon D810 digital camera and written to internal camera cards. Image size is approximately 24 megapixels. Images in JPEG format were saved using the filename format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using the Nikon D810). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2016_0218_133636d.jpg was taken February 18, 2016, at 13:36:36 UTC. Best effort was made to set the Nikon D810's internal clock to within 1 second of UTC at the beginning of the flight. Person who carried out this activity:

    Navigation processing: Using a custom Practical Extraction and Reporting Language (Perl) script written by Karen Morgan of the USGS, GPS data and image files were used to generate comma-separated value (CSV) files containing latitude, longitude, and time record for each image. Each processed navigation file was saved as a CSV file, ds1029_2016-316-FA-A.csv, using Microsoft Excel 2011. Person who carried out this activity:

    HTML Creation: The digital images were organized into 5-minute (time) segments. These 5-minute segments were used to create HTML pages called contact sheets. A contact sheet was created for every 5-minute segment of the survey. The contact sheets contain thumbnails of each of the photographs. Each thumbnail links to the corresponding full-size area map or photograph. Person who carried out this activity:

    Geospatial Processing: The spreadsheets containing navigation data were edited using Microsoft Excel 2011 and saved as comma-separated value (CSV) files to make them compatible with ArcGIS software. The latitude/longitude data from the CSV navigation file, called XSTORMS.h20160218_photographs, were used to produce ESRI shapefiles using ArcGIS 10.1. These shapefiles were used to produce the JPEG maps included in this report. The shapefiles are not included in this report. Person who carried out this activity:

    Google Earth file creation: The Keyhole Markup Language (KML) files were created using the photographic navigation file ds1029_2016-316-FA-A.csv. The storm track (in KML format) was provided by the National Oceanic and Atmospheric Administration (NOAA). The USGS is the originator of all other layers. To assist users in navigating the KML file, each image was assigned a sequential KML number. Table 1 of this report shows the KML number given to each image, the corresponding image name, and associated attributes. Each point, when clicked on in the Google Earth, shows the KML number, storm name, latitude, longitude, image name, geographic area, date, time, a thumbnail of the full-size photograph, and links to the full-size photographs and contact sheets.

  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?
    Best attempts were made to set the camera to UTC time on the GPS receivers at the beginning of each flight. Latitude, longitude, and time were collected at an interval of approximately once every 3 to 5 seconds. NOTE: Latitude and longitude positions in this report refer to the position of the aircraft, not the position of the landmarks photographed. Refer to the Process Steps below for more detail.
  2. How accurate are the geographic locations?
    Best attempts were made to maintain the same relative distance between the aircraft and the beach in order to keep a constant field of view.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    no known issues
  5. How consistent are the relationships among the observations, including topology?
    Data presented here include the digitally collected photographs in JPEG format with Exchangeable Image File (EXIF) header embedded with the individual photograph's location along the flight path of a Winter 2016 coastal oblique aerial photographic survey of the coast, taken from the South Carolina/North Carolina border to Assateague Island, Virginia. This mission was conducted on February 18-19, 2016, aboard a Cessna 182 aircraft, tail number N8479S. Crew members, contracted by the USGS in St. Petersburg, Fla., included Carol McManus, photography contractor, and pilot Lee McManus of Top Cover Virginia, LLC. Still photography was collected along the coast during this survey. GPS Data Collection - Instrument: Garmin GPSMAP 696. Data Collection Interval: Variable, every 5-15 seconds. Data File Format: ASCII. Number of files created: 1. Computer/Software: none. Software: none. The GPS unit was used to record navigation fixes of the aircraft, not the position of the features imaged.
