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 January 22, 2011, the USGS conducted an oblique aerial photographic survey at Breton Island and the Chandeleur Islands, LA, aboard a Cessna 210 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 2010 (
http://cmgds.marine.usgs.gov/fan_info.php?fan=10CCH02) (unpublished), and the data can be used as a baseline to assess future coastal change.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 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).
Purpose:
To provide access to digital photographs taken as part of the January 22, 2011, baseline oblique aerial survey collected along the coast at Breton Island and the Chandeleur Islands, LA, and to provide access to attribute data that documents the time and location where each photograph was taken.
Supplemental_Information:
For a summary of field activity 11CCH01 please see
