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 July 26-27, 2007, the USGS conducted an oblique aerial photographic survey from Dauphin Island, Alabama, to Breton Island, Louisiana, aboard a U.S. Coast Guard HH60 Helicopter 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 and can also 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. All image times are recorded in Coordinated Universal Time (UTC).
To provide access to digital photographs taken as part of the July 26-27, 2007, baseline oblique aerial survey collected along the coast from Dauphin Island, Alabama, to Breton Island, Louisiana, and to provide access to attribute data that documents the time and location where each photograph was taken.

Browse_Graphic_File_Description: Map of survey area during USGS field activity 07CCH01.
Maps showing the extent of each area and 5-minute segment can be found in the 07CCH01-LocationMaps.zip file. The maps in this survey are: 07CCH01-Map-Area01.jpg, Area 1 for Dauphin Island, Alabama; 07CCH01-Map-Area02.jpg, Area 2 from Dauphin Island, Alabama, to Petit Bois Island, Mississippi; 07CCH01-Map-Area03.jpg, Area 3 from Petit Bois Island, Mississippi, to Breton Island, Louisiana, and the inset map for Dauphin Island (07CCH01-Map-Inset01_Dauphin.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 authors wish to thank Lt. Patrick Bachan and Lt. Bryan Bailey (pilot), Lt. Matt Furlong and Lt. Dave Aldous (copilot), and AMT3 Steve Fruzan and AET Molleye Curry (flight mechanic) of the U.S. Coast Guard for their assistance with data collection.
