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 August 24, 2011, the USGS conducted an oblique aerial photographic survey from Ponte Vedra, Florida, to the South Carolina/North Carolina border, aboard a Piper Navajo Chieftain 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 since the last survey, which was flown in September 1996 (https://cmgds.marine.usgs.gov/fan_info.php?fan=96ACH05) (unpublished), and the data can be used to assess future coastal change.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 an estimate of the aircraft's position and do not indicate the location of the feature 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 August 24, 2011, baseline oblique aerial survey collected along the coast from Ponte Vedra, Florida, to the South Carolina/North Carolina border, and to provide access to attribute data that documents the time and location where each photograph was taken.
For a summary of field activity 11CCH03 please see https://cmgds.marine.usgs.gov/fan_info.php?fan=11CCH03. 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: 11CCH03-LocationMaps.zip, 11CCH03-ProcessedNav.zip, 11CCH03-SupplementalFiles.zip, and 11CCH03-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 11CCH03-LocationMaps.zip file. The maps in this survey are: 11CCH03-Map-Area01.jpg, Area 1 is from Ponte Vedra, Florida, to Ossabaw Island, Georgia; 11CCH03-Map-Area02.jpg, Area 2 is from Ossabaw Island, Georgia, to Morris Island, South Carolina; 11CCH03-Map-Area03.jpg, Area 3 is from Morris Island, South Carolina to the South Carolina/North Carolina border. 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 Mitch Bobowski for his assistance with data collection. Native_Data_Set_Environment: Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.3. This report benefited from the comments and review of Kara Doran with the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC), St. Petersburg, FL.
Best attempts were made to set the camera to UTC time on the GPS receivers at the beginning of each flight. once per second. once per second. 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.
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, taken from Ponte Vedra, Florida, to the South Carolina/North Carolina border. This mission was flown on August 24, 2011, aboard a Piper Navajo Chieftain aircraft, tail number N2KK. Crew members of the USGS in St. Petersburg, FL., included Karen L. M. Morgan, M. Dennis Krohn, and Kristy Guy, and pilot Mitch Bobowski of Bay Air Charters, Inc Still photography was collected along the coast during this survey. GPS Data Collection—Instrument: Garmin GPS 18 PC, WAAS Enabled. Data Collection Interval: 1 Second. Data File Format: Native Fugawi and Text; Number of files created: 2. Computer/Software: # Computer: Panasonic Toughbook CF-51. Software: Fugawi Marine ENC, Ver. 4 GPS Navigation Software.
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 GPS 18 PC 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.The GPS receiver used to provide navigation is accurate to within 15 meters (m). The GPS unit was used to record navigation fixes of the aircraft, not the position of the features imaged.
Images were converted to JPEG format using Nikon Capture Camera Editor Ver 4.4.2. Images in JPEG format were saved using the filename format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using the Nikon D1X). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2011_0824_133636d.jpg was taken August , 2011, at 13:36:36 UTC. Best attempts were made to set the Nikon D1X camera's internal clock to within 1 second of UTC at the beginning of the flight.

Navigation processing: Using a custom Practical Extraction and Reporting Language (Perl) script written by Karen Morgan, USGS, GPS data and image files were used to generate CSV file containing a latitude, longitude, and time record for each image.

The imagery in this release was divided into manageable sized (<450MB) zip files for ease of download and review. Subareas may be designed within those areas to conform to zip file size requirements for downloading.
