Title:
Archive of Post-Hurricane Isabel Coastal Oblique Aerial Photographs Collected during USGS Field Activity 03CCH01 from Ocean City, Maryland, to Fort Caswell, North Carolina, and Inland from Waynesboro to Redwood, Virginia, September 21 - 23, 2003
Abstract:
On September 21 - 23, 2003, the U.S. Geological Survey (USGS) conducted an aerial survey along the Atlantic coast, from Ocean City, Maryland, to Fort Caswell, North Carolina, and inland from Waynesboro to Redwood, Virgina. These photos were used to document coastal changes such as beach erosion and overwash caused by Hurricane Isabel and to identify potential landslide areas inland. They may also be used as baseline data for future surveys. The USGS and the National Aeronautics and Space Administration (NASA) surveyed the impact zone of Hurricane Isabel to better understand the changes in vulnerability of the Nation’s coasts to extreme storms (Morgan, 2009). This report serves as an archive of the post-Hurricane Isabel oblique aerial survey photographs, survey maps, Google Earth files, location tables, navigation files, digital Field Activity Collection System (FACS) logs, and Federal Geographic Data Committee (FGDC) metadata. Attribute data including links to digital scans of the photographs are also provided. Latitude, longitude, and time were gathered simultaneously from three sources: video (with latitude/longitude and time stamps), photographs (with time stamps), and three Precision Lightweight GPS Receiver (PLGR) navigation files (without time) that documented the location of the aircraft. Location data were converted to decimal degrees and merged to create a location and time file that provided estimated location information for where each photograph was taken (see process step below). Slides were digitally scanned as TIFF image files at 3,000 dots per inch and were converted to JPEG images which are provided here. The metadata values for photo creation time, GPS latitude, GPS longitude, GPS position (latitude and longitude), keywords, credit, artist, caption, copyright, and contact were added to each photograph's EXIF header. Refer to the process steps below for more detail on each of these steps.

    Date: 21-Sep-2003 (process 1 of 16)
    Photographs were taken with two Nikon F3 cameras, each with a fixed 50-millimeter lens and UV filter. One camera shot the odd-numbered film rolls, and the other camera shot the even-numbered film rolls. Both cameras were equipped with a Nikon MF-14 data back, which added day of month, hour, and minute (UTC) to the lower right-hand corner of each photo. Rolls were numbered by hand when loaded into the cameras, and the end of a roll is noted in the audio track of the video. Film used was Kodak Ektachrome E100G. Commonly used shutter speeds were 1/250 seconds or 1/125 seconds. A constant shutter speed was attempted but may vary if there was a noticeable change in light levels. Initial shutter speed and any subsequent changes are noted on the audio track of the video. The f-stop was changed frequently to compensate for changes in light levels. All photographs were taken from the second-to-last rear starboard window of the airplane. Video collection equipment consisted of a Panasonic AG-5700 recording to S-VHS tapes. Independent of all other equipment, a Rockwell Collins PLGR GPS recorded navigation fixes, at 30-second intervals, from a NMEA string during the flight. A Compix Titler unit provided video subtitles that include latitude (WGD), longitude (WGD), and time (hr:min:sec). Navigation was provided to the video by a Trimble Centurion GPS receiver, and time was provided by the titler unit's internal clock, which had been synchronized with UTC time. The video was shot out of the last starboard window of the airplane.

    Slide names (year_monthday_roll number_slide number) and time (hour, minute) were manually entered into a Microsoft Excel 2003 spreadsheet. 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. It is assumed, for the purposes of location, that the photographs were taken at a constant rate during any given minute of flight. To assign a time value in seconds to each photograph, the number of photographs taken during each minute was evenly distributed across those 60 seconds. For example, if 15 photographs were taken during minute 19:00, we assume that a picture was taken every 4 seconds. The photographs were then assigned the time values 19:00:00, 19:00:04, 19:00:08, and so on. 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. This file was named slides.xls. The photograph names provide information about the photograph's year, date, roll number, and slide number. For example, slide 2003_0921_r030s01 was taken September 21, 2003, and is the first slide for roll 30. Person who carried out this activity:

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Best attempts were made to set the camera to UTC time on the GPS receivers at the beginning of each flight. The clock of the Compix Titler unit was also set to UTC at the same time. Human error during transcription of geographic position and time from the video is possible; however, no obvious errors were observed. Latitude, longitude, and time were linearly interpolated from known navigation (collected every 30 seconds) and time stamps (collected every 1 minute). NOTE: Latitude and longitude positions in this report refer to the position of the aircraft, not the position of the landmarks photographed. Refer to the Process Steps below for more detail.
  2. How accurate are the geographic locations?
    The GPS receiver used to provide navigation to the video titler unit was a Trimble Centurion, which is accurate to within about 100 meters. Independent of all other equipment, a Rockwell Collins PLGR GPS unit, also accurate to within about 100 meters, recorded navigation fixes. Best attempts were made to keep the same relative distance between the aircraft and the beach in order to keep a constant field of view.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Some film roll numbers may be missing due to being skipped accidentally or to the film not threading correctly. No photographs were taken during the 5-min segment beginning at 2003_0922_131919, 2003_0922_134000, 2003_0923_173630, 2003_0923_174000, and 2003_0923_174500. Video collected during this flight is not included in this report.
  5. How consistent are the relationships among the observations, including topology?
    Data presented here include the digitally scanned analog photographs in JPEG format with EXIF headers imbedded and the location of the flightpath of post-Hurricane Isabel coastal oblique aerial photographic survey of the Atlantic coast, from Ocean City, Md., to Fort Caswell, N.C. and Inland from Waynesboro to Redwood, Va., which was flown September 21 - 23, 2003, aboard a Piper Navajo twin-engine airplane. Crew members were D. Krohn, K. Morgan, and R. Peterson of the USGS in St. Petersburg, Fla., and pilot K. Miller. Crew members took video and still photography along the coast during this survey. Two GPS units, a Trimble Centurion GPS and a Rockwell Collins Precision Lightweight GPS Receiver (PLGR), were used to record navigation fixes of the plane.
