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 June 9, 2011, the USGS conducted an oblique aerial photographic survey from Dauphin Island, Alabama, to Breton Island, Louisiana, aboard a Beechcraft BE90 King Air aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore (fig. 2,
http://pubs.usgs.gov/ds/1044/html/ds1044_fig2.html). This mission was flown to collect data for assessing incremental changes in the beach and nearshore area since the last survey, flown in January 2011 (Chandeleur Islands, and Breton Island, Louisiana) (
http://cmgds.marine.usgs.gov/fan_info.php?fan=11CCH01) (unpublished); July 2010 (Dauphin Island, Alabama) (
http://cmgds.marine.usgs.gov/fan_info.php?fan=10CCH01) (unpublished); and September 2008 (Petit Bois Island, Mississippi, to Cat Island, Mississippi) (
http://cmgds.marine.usgs.gov/fan_info.php?fan=08ACH06) (Morgan, 2016, [
https://doi.org/10.3133/ds990]). 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 position of the aircraft and do not indicate the location of the feature in the images (See the Navigation Data page,
http://pubs.usgs.gov/ds/1044/html/ds1044_nav.html). 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 photo: time of collection, Global Positioning System (GPS) latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. Photographs can be opened directly 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/1044/html/ds1044_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 clicking on either 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 navigation of the Google Earth file. These numbers correspond to the site labels in Google Earth.
Purpose:
To provide access to digital photographs taken as part of the June 9, 2011, 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 of where each photograph was taken.
Supplemental_Information:
For a summary of field activity 11CCH02 please see
http://cmgds.marine.usgs.gov/fan_info.php?fan=11CCH02. 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 ds1044_11CCH02.csv, and ds1044_11CCH02.kml, in addition to the digital oblique aerial image files.
