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 September 7, 2016, the USGS conducted an oblique aerial photographic survey from Navarre Beach, Florida, to Breton Island, Louisiana, aboard a Maule MT57 aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore. This mission was conducted to collect data for assessing incremental changes in the beach and nearshore area since the last survey, which was flown in September 2016 (https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-335-FA) (Morgan, 2016, [https://dx.doi.org/10.3133/ds1008]), and the data can be used as a baseline to assess future coastal change. The photographs provided are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the aircraft's position and do not indicate the location of the features in the images. These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. ExifTool (version 4.0) was used to add the following to the header of each photograph: time of collection, 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).
To provide access to digital photographs taken as part of the September 7, 2016, baseline oblique aerial survey collected along the coast from Navarre Beach, Florida, to Breton Island, Louisiana, and to provide access to attribute data that documents the time and location where each photograph was taken.
For a summary of field activity 2016-354-FA please see https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-354-FA. Bounding coordinates for the oblique aerial survey are derived from the overall flight path found in the GPS data. Ancillary files included in this publication are: 2016-354-FA-LocationMaps.zip, 2016-354-FA-ProcessedNav.zip, 2016-354-FA-SupplementalFiles.zip, and 2016-354-FA-RawGPSNav.zip; in addition to the digital oblique aerial image zip files.

Maps showing the extent of each area and 5-minute segment can be found in the 2016-354-FA-LocationMaps.zip file. The maps in this survey are: 2016-354-FA-Map-Area01.jpg, Area 1 from Navarre Beach, Florida, to Dauphin Island, Alabama; 2016-354-FA-Map-Area02.jpg, Area 2 from St Petit Bois Island, Mississippi, to Breton Island, Louisiana; and 2016-354-FA-Map-Area03.jpg, Area 3 from Navarre Beach, Florida, to Pensacola Beach, Florida, and inset maps for Dauphin Island (2016-354-FA-Map-Inset01_Dauphin.jpg), West Ship Island (2016-354-FA-Map-Inset02_Westshipisland.jpg), and Northern Benchmark (2016-354-FA-Map-Inset03_Northbenchmark.jpg). The flight path, divided into 5-minute segments, is represented by the alternating purple and yellow lines.

Funding and support for this study were provided by the USGS Coastal and Marine Geology Program (CMGP). The author wishes to thank pilot Ian McIntyre for his assistance with data collection. This report benefited from the comments and review of Julie C. Bernier with the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC), St. Petersburg, Florida.
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 per second. Note: Latitude and longitude positions in this data release refer to the position of the aircraft, not the position of the landmarks photographed. Refer to the Process Steps below for more detail.
Data presented here include the digitally collected photographs in JPEG format with the Exchangeable Image File (EXIF) header embedded with the individual photograph's location along the flight path of the baseline coastal oblique aerial photographic survey of the coast, from Navarre Beach, Florida, to Breton Island, Louisiana. This mission was flown on September 7, 2016, aboard a Maule MT57 aircraft, tail number N5500K. Crew members, contracted by the USGS in St. Petersburg, Florida, included Amy Hartsfield, photography contractor, and pilot Ian McIntyre of Amy & Company, Inc. The GPS receiver used to provide navigation is accurate to within 2 meters (m). 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. The GPS unit was used to record navigation fixes of the aircraft, not the position of the features imaged.
This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details.
An attempt was made to keep the same relative distance between the aircraft and the beach in order to maintain a constant field of view.

Garmin GPSMAP 196 accuracy is based on manufacturer specifications when available and provided in meters. During post-processing, the camera time was matched to the GPS time/position to determine camera location at the time of image collection. Latitude and longitude positions in this data release refer to the position of the aircraft, not the position of the landmarks photographed.
Image Acquisition: Images were taken with a Canon EOS 5DS digital camera and written to internal camera cards. Image size is approximately 50 megapixels. Images in JEPG format were saved using the filename format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using Canon EOS 5DS). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2016_0907_133636d.jpg was taken September 7, 2016, at 13:36:36 UTC. Best attempts were made to set the Canon EOS 5DS's internal clock to within 1 second of UTC at the beginning of the flight.

EXIF headers: Exchangeable Image File (EXIF) and International Press Telecommunications Council (IPTC) headers were populated from the command prompt using ExifTool (https://www.sno.phy.queensu.ca/~phil/exiftool, 2017) as part of the post flight processing using a Perl script written by Karen Morgan, USGS, St. Petersburg, FL. ExifTool added the following data to the EXIFHeader: time of collection, GPS latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information.

Google Earth file creation: The KML files were created using the photographic navigation file 10CCH02-Photolocations.csv. The USGS is the originator of all other layers. To aid navigation through the Keyhole Markup Language (KML) file, each image was assigned a sequential KML number. Each point on the Google Earth file contains the KML number, storm name, latitude, longitude, image name, date, time, a thumbnail of the full-size photograph, and links to the full-size photographs.
