The images provided here 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 configuration 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.
Due to equipment restrictions by the USCG, no GPS data was collected during the flight. Image positions were post-processed using two previous flights, May 2008 and May 2009, by matching image features and assigning the GPS location of the previous flight's image to the corresponding image from this flight. Matches were made along the coast approximately every one to two minutes of flight time. The time of capture (timestamp) for each image was recorded in the image header during the flight. Based on the timestamp from the camera, a time was assigned to each GPS location, and then the estimated GPS track for the whole flight was calculated at a resolution of one position per second per record. The positions of the remaining images were then interpolated to give the best GPS position for each image. The estimated time file can be found in the nav folder.
Table 1 provides detailed information about the GPS location, name, date, and time for each of the 2,381 photographs taken along with links to each photograph. The photography is organized into segments, also referred to as contact sheets. Each segment represents approximately 5 minutes of flight time. (Also see the Photos and Maps page).
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. These KML files can be found in the kml folder.
This report is divided into seven sections Home, Abbreviations, Contents, Photos and Maps, Navigation Data, Logs, Metadata and an Index page. Links at the top and bottom of each page provide access to these sections. (If you are viewing this report on DVD, use a Web browser to open the file index.html.)
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 in Navigation Data. The Logs pages contain 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.
