Project Summary On August 15, 2004, the USGS conducted an oblique aerial photographic survey off the southwest coast of Florida, south to north from Marco Island to Fort DeSoto, aboard a N2KK Navajo Chieftain airplane, tail number N2KK, at an altitude of 500 ft, approximately 1,000 ft offshore. These photos, along with the Experimental Advanced Airborne Research Lidar (EAARL) coastal topography and bathymetry data collected on August 16, 2004 (Bonisteel and others, 2009), are also used to ground truth the lidar data that were also collected shortly after Hurricane Charley. This report serves as an archive of the photographs collected during the August 15, 2004, Post-Hurricane Charley Coastal Oblique Aerial Survey along with associated trackline maps, Keyhole Markup Language (KML) files, navigation files, digital Field Activity Collection System (FACS) logs, and Federal Geographic Data Committee (FGDC) metadata. Two separate records of flight navigation were collected during the survey. The first was a continuous ASCII text file from the PLGR that recorded only latitudes, longitudes, and altitudes every 30 sec for the entire flight. No time values were recorded by the PLGR. The second navigation record was recorded by a Trimble Centurion GPS and converted to subtitles on the video, using a Compix Titler unit. The video was shot continuously during the survey. The video subtitles recorded day, month, year, latitude, longitude, and time in hours, minutes and seconds. In order to produce a digital record of the navigation that included latitude, longitude, and time, each was manually extracted from the video every 5 min, and these values were matched to the latitude and longitude in the PLGR file. Next, the time was interpolated between these 5-min fixes using Excel to produce a 1-sec time value record for the entire flight. The location of each photograph was determined in the following manner. A Nikon MF-14 data back marked the time each photograph was acquired on the lower right corner of the image in day, hour, and minute format (in Universal Time Coordinated - UTC). These values were entered from the photographs into an Excel spreadsheet. It is assumed for the purposes of locating the images that the photographs were taken at a constant rate during any given minute of flight. To assign the time value in seconds to each photograph, the number of photographs taken during each minute is evenly distributed across that minute. For example: if 15 photographs were taken during minute 19:00:00, we assume that a picture was taken every 4 sec. The photographs were assigned the time values 19:00:00, 19:00:04, 19:00:08, and so on. The video time navigation file was then merged with the new interpolated photograph file based on time to produce the point at which each photograph was collected. As a result it should be noted that the positions assigned to each photograph are an estimate of the aircraft position, not the location of the landmark photographed. The photographs provided here are JPEG scanned images of the analog slides. The metadata values for photo creation time, GPS latitude, GPS longitude, GPS position, keywords, credit, artist, caption, copyright, and contact were added to each photograph's EXIF header using EXIFtools. Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet, or, when viewing the Google Earth KML file, by clicking on the marker and then clicking on either the thumbnail or the link below the thumbnail. The KML files were created using the photographic navigation files and the CreateKML JavaScript. To view the survey maps and navigation files, and for more information about these items, see the Navigation page. Figure 1 displays the acquisition geometry. The tables provide detailed information about the assigned location, name, data, and time the photograph was taken along with links to the photo and corresponding 5-min contact sheet. Refer to table 1 and table 2 for details of the northern and southern county photographs, respectively. Disc Organization This report contains links to other available resources if access to the Internet is available while viewing these documents. KML files, Hypertext Markup Language (HTML) files and images used to produce the Web pages, and this readme file are also included in this report. Links at the top and bottom of each page provide access to these sections. The survey's full-size photographs have been split up into two discs, northern counties (Disc 1) and southern counties (Disc 2) (see full survey area map). Each disc contains a KML file with links to the related full-size photographs. The data provided in this report will also be served via the World Wide Web from the USGS publications server. The Disc Contents page is a diagram of the location of all files and folders mentioned in the text and provides links to these files and folders. Getting Started To access the information contained on this disc, use a Web browser to open the file index.html.
