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 August 8, 2012, the USGS conducted an oblique aerial photographic survey from Dauphin Island, Alabama, to Breton Island, Louisiana, aboard a Cessna 172 aircraft at an altitude of 500 feet (ft) and approximately 1,000 ft offshore (Figure 2). This mission was flown to collect data for assessing incremental changes since the last survey and can be used for assessing future coastal change. The photographs provided here are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the position of the aircraft do not indicate the location of the feature in the images (see the Navigation Data page). These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. Exiftool 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 UTC.Table 1 provides detailed information about the assigned location, name, data, 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 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 August 08, 2012, 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.

Images were written to internal camera cards. Image size is approximately 18 megapixels. Images in JPG format were saved using the file name format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using the Canon EOS Rebel). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2012_0808_133636d.jpg was taken August 08, 2012, at 13:36:36 UTC. Best effort is made to set the Canon EOS Rebel's internal clock to within 1 second of UTC at the beginning of the flight.

The digital images were organized into 5-minute (time) segments. These 5-minute segments were used to create HTML pages, called contact sheets. A contact sheet was created for every 5-minute segment of the survey. The contact sheets contain thumbnails of each of the photographs. Each thumbnail links to the corresponding full-size area map or photograph.
