Title:
Baseline Coastal oblique aerial photographs collected from Horseshoe Beach, Florida, to East Cape, Florida, May 19-20, 2010
Abstract:
The U.S. Geological Survey (USGS) conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms. On May 19-20, 2010, the USGS conducted an oblique aerial photographic survey from Horseshoe Beach, Florida, to East Cape, Florida, aboard a Piper Navajo Chieftain aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore. This mission was conducted to collect data for assessing incremental changes in the beach and nearshore area and can be used to assess future coastal change. The photographs provided are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the aircraft's position and do not indicate the location of the feature in the images. These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. ExifTool (version 4.0) was used to add the following to the header of each photograph: time of collection, GPS latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. Photographs can be opened 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).

Why was the data set created?

To provide access to digital photographs taken as part of the May 19-20, 2010, baseline oblique aerial survey collected along the coast from Horseshoe Beach, Florida, to East Cape, Florida, and to provide access to attribute data that documents the time and location where each photograph was taken. The photographs in this survey serve the joint purpose of documenting the mangroves found long the intercoastal waterway, and the configuration of the beach on the exposed Gulf coastline.

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 19-May-2010 (process 1 of 5)
    Images were converted to JPEG format using Nikon Capture Camera Editor Ver 4.4.2. Images in JPG format were saved using the filename format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using the Nikon D1X). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2010_0519_133636d.jpg was taken May 19, 2010, at 13:36:36 UTC. Best attempts were made to set the Nikon D1X camera's internal clock to within 1 second of UTC at the beginning of the flight.
    Date: 30-May-2010 (process 2 of 5)
    Navigation processing: Using a custom Practical Extraction and Reporting Language (Perl) script written by Karen Morgan, USGS, GPS data and image files were used to generate CSV file containing a latitude, longitude, and time record for each image.

  4. Where are the gaps in the data? What is missing?
    This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details. Crew members included pilot Mitch Bobowski (Bay Air Charters, Inc.), Karen L.M. Morgan, Thomas J. Smith, Ginger Range, and Paul Nelson (SPCMSC). Still photography was collected along the coast during this survey. GPS Data Collection—Instrument: Garmin GPS 18 PC, WAAS Enabled. Data Collection Interval: 1 Second. Data File Format: Native Fugawi and Text; Number of files created: 2. Computer/Software: Computer: Panasonic Toughbook CF-51. Software: Fugawi Marine ENC, Ver. 4 GPS Navigation Software.
  5. How consistent are the relationships among the observations, including topology?
    Data presented here include the digitally collected photographs in JPEG format with the Exchangeable Image File (EXIF) header embedded with the individual photograph's location along the flight path of the baseline coastal oblique aerial photographic survey of the coast, taken from Horseshoe Beach, Florida, to East Cape, Florida. This mission was flown on May 19-20, 2010, aboard a Piper Navajo Chieftain aircraft, tail number N2KK.
