Title:
Baseline coastal oblique aerial photographs collected from Navarre Beach, Florida, to Breton Island, Louisiana, September 18–19, 2015
Abstract:
The U.S. Geological Survey (USGS) conducts baseline and storm-response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms. On September 18–19, 2015, the USGS conducted an oblique aerial photographic survey from Navarre Beach, Florida, to Breton Island, Louisiana (fig. 1, http://pubs.usgs.gov/ds/1008/downloads/maps/index.jpg), aboard a Maule MT57 aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore (fig. 2, http://pubs.usgs.gov/ds/1008/html/ds1008_fig2.html). This mission was conducted to collect data for assessing incremental changes since the last survey, which was flown September 2014 (http://cmgds.marine.usgs.gov/fan_info.php?fan=2014-326-FA) and can be used for assessing future coastal change. The photographs provided are Joint Photographic Experts Group (JPEG) images. The photograph locations are estimates of aircraft positions and do not indicate the location of the feature in the images (See the Navigation Data page, http://pubs.usgs.gov/ds/1008/html/ds1008_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 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/1008/html/ds1008_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 on 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 aid in navigation of the Google Earth file. These numbers correspond to the site labels in Google Earth.
Supplemental_Information:
For a summary of field activity 2015-335-FA, please see http://compass.er.usgs.gov/fan_info.php?fan=2015-335-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 ds1008_2015-335-FA_0918_gpsmap196.txt; ds1008_2015-335-FA.csv; and ds1008_2015-335-FA.kml, in addition to the digitized oblique aerial image files. Note: The GPS time stamp was not recorded during the first leg of the flight on September 18, 2015 (Navarre Beach, Florida to Ship Island, Mississippi). While the GPS position remains accurate, the position of the photographs along that flight line are estimated and might contain a larger positional error than other imagery in this data series. The photographs subject to this possible error were taken between 14:26:08 GMT and 16:27:45 GMT on September 18, 2015.

    Image Acquisition: Images were taken with a Canon EOS 5D Mark III and written to internal camera cards. Image size is approximately 22 megapixels. Images in JPG format were saved using the filename format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using Canon EOS 5D Mark III). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2015_0918_133636d.jpg was taken September 18, 2015, at 13:36:36 UTC.

To aid navigation through the Keyhole Markup Language (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 on the Google Earth file contains 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 on the GPS receivers at the beginning of each flight. Latitude, longitude, and time were collected at an interval of approximately once every 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 to keep a constant field of view. Note: The GPS time stamp was not recorded during the first leg of the flight on September 18, 2015 (Navarre Beach, Florida to Ship Island, Mississippi). While the GPS position remains accurate, the position of the photographs along that flight line are estimated and might contain a larger positional error than other imagery in this data series. The photographs subject to this possible error were taken between 14:26:08 GMT and 16:27:45 GMT on September 18, 2015.
  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 baseline coastal oblique aerial photographic survey of the coast, taken from Navarre Beach, Florida, to Breton Island, Louisiana. This mission was flown on September 18–19, 2015, aboard a Maule MT57 aircraft, tail number N5500K. Crew members, contracted by the USGS in St. Petersburg, Fla., include Amy Hartsfield, photography contractor, and pilot, Ian McIntyre, of Amy & Company, Inc. Still photography was collected along the coast during this survey. GPS Data Collection Instrument: Garmin GPSMAP 196. Data Collection Interval: 1 Second. Data File Format: Text. Number of files created: 1. Computer/Software: none. Computer: none. The GPS unit was used to record navigation fixes of the aircraft, not the position of the features imaged.
