Baseline coastal oblique aerial photographs collected from Navarre Beach, Florida, to Breton Island, Louisiana, September 1, 2014

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 September 1, 2014, the USGS conducted an oblique aerial photographic survey from Navarre Beach, Florida, to Breton Island, Louisiana, aboard a Maule MT57 aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore (Figure 2, http://pubs.usgs.gov/ds/0952/html/ds952_fig2.html). This survey was flown to collect data for assessing incremental changes since the last survey, flown July 2013, 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 and aircraft do not indicate the location of the feature in the images (see the Navigation Data page for additional details, http://pubs.usgs.gov/ds/0952/html/ds952_nav.html). These photographs document the configuration of the barrier islands and other coastal features at the time  of the survey. CSV: Comma separate values files representing table information collected during the flight. JPEG: Images can be opened directly with any JPEG-compatible image viewer. The survey's full-size photographs are divided into ?two ?areas. KML: ds952_2014-?326-FA.kml has? 1,111 photographs. TXT: Text files representing the navigation files, FACS log, metadata and readme files collected during and after the survey. KML: The KMLs provided may be viewed with Google Earth (http://www.google.com/earth/download/ge/agree.html). ExifTool (http://www.sno.phy.queensu.ca/~phil/exiftool/) is a free software program for reading, writing, and manipulating image, audio, and video metadata. 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 Coordinated Universal Time (UTC). Table 1 (http://pubs.usgs.gov/ds/0952/html/ds952_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.
