The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards Project, conducts baseline and storm response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms (Morgan, 2009). On September 17, 2004, the USGS conducted an oblique aerial photographic survey from Crawfordville, Florida, to Petit Bois Island, Mississippi (Figure 1), aboard a Piper Navajo Chieftain (aircraft) at an altitude of 500 feet (ft) and approximately 1,000 ft offshore (Figure 2). This mission was flown to collect post-Hurricane Ivan data for assessing incremental changesin the beach and near shore since the last survey, flown in July 2001, and can be used in the assessment of future coastal change. The flight initially surveyed westward from Crawfordville, through Dauphin Island, Alabama, and then proceeded to Gulfport, Mississippi, to refuel (Areas 1-3). The flight then departed eastward from Gulfport and transited along the gulfward side of the islands to Fort McRee, Florida. It then turned westward and surveyed along the barrier islands through Petit Bois Island (Area 4). After completing the survey the flight turned around and transited eastward along the islands, taking photographs using the then experimental Nikon D1X and shooting out the left side of the aircraft, before returning to St Petersburg, Florida (Area 5).
The photographs provided in this report are Joint Photographic Experts Group (JPEG) images. 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. The photograph locations are an estimate of the position of the aircraft and do not indicate the location of any feature in the images (see the Navigation Data page). These photographs document the state of the barrier islands and other coastal features at the time of the survey. Pages containing thumbnail images of the photographs, referred to as contact sheets, were created in 5-minute segments of flight time. These segments can be found on the Photos and Maps page. Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet.
Table 1 provides detailed information about the GPS location, image name, date, and time for each of the 3,381 photographs taken along with links to each 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.
This report is divided into eight sections: Home, Abbreviations, Contents, Photos and Maps, Navigation Data, Logs, Metadata, and Index. Links at the top and bottom of each page provide access to these sections.
Links to the full-sized images can be found through the Photos and Maps page and through Table 1. KML files, Hypertext Markup Language (HTML) files, images used to produce the Web pages, and a readme file are also included in this report. Global Positioning System (GPS) data collected during the flight are also available on the Navigation Data page. The Logs page contains information on the flight and the equipment used. The Contents page contains a diagram of the location of all files and folders mentioned in the text and provides links to these files and folders.
