Title:
Baseline coastal oblique aerial photographs collected from Key Largo, Florida, to the Florida/Georgia border, September 5-6, 2014
Abstract:
The U.S. Geological Survey (USGS) conducts baseline and storm response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms. On September 5-6, 2014, the USGS conducted an oblique aerial photographic survey from Key Largo, Florida, to the Florida/Georgia border aboard a Cessna 182 aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore (Figure 2, http://pubs.usgs.gov/ds/0953/html/ds953_fig2.html). This mission was flown to collect data for assessing incremental changes since the last survey, flown October 1998, and can be used for assessing future coastal change. The photographs provided here are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the position of the aircraft and do not indicate the location of the feature in the images (see the Navigation Data page, for additional details: http://pubs.usgs.gov/ds/0953/html/ds953_nav.html). These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. ExifTool (http://www.sno.phy.queensu.ca/~phil/exiftool/) is a free software program for reading, writing, and manipulating image, audio, and video metadata. ExifTool (http://www.sno.phy.queensu.ca/~phil/exiftool/) is a free software program for reading, writing, and manipulating image, audio, and video metadata. 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. Photographs can be opened directly 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). Table 1 (http://pubs.usgs.gov/ds/0953/html/ds953_table.html) provides detailed information about the assigned location, name, date, and time the photograph was taken along with links to the 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. Note: A KML number was assigned to each photograph to aid navigation of the Google Earth file. These numbers correspond to the site labels in Google Earth.

    Images were written to internal camera cards. Image size is approximately 24 megapixels. Images in JPEG format were saved using the file name format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using the Nikon D7100). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2014_0905_133636d.jpg was taken September 5, 2014, at 13:36:36 UTC. Best effort is made to set the Nikon D7100's internal clock to within 1 second of UTC at the beginning of the flight. Person who carried out this activity:

    Navigation processing: Using a custom Perl script written by K. Morgan of the USGS, GPS data and image files were used to generate CSV files containing latitude, longitude, and time records for each image. Each processed navigation file was saved as a comma-separated value (CSV) file, ds953_2014-327-FA.csv, using Microsoft Excel 2011. Person who carried out this activity:

    The digital images were organized into 5-minute (time) segments. These 5-minute segments were used to create HTML pages, called contact sheets. A contact sheet was created for every 5-minute segment of the survey. The contact sheets contain thumbnails of each of the photographs. Each thumbnail links to the corresponding full-size area map or photograph. Person who carried out this activity:

    Geospatial Processing: The processed navigation file was edited using Microsoft Excel 2011 and saved as CSV file to make them compatible with ArcGIS software. The latitude/longitude data from the CSV navigation file were used to produce an Environmental Systems Research Institute (Esri) shapefiles using ArcGIS 10.1. These shapefiles were used to produce the JPEG maps included in this report; however, the shapefiles were not included in this report. Person who carried out this activity:

    Google Earth file creation: The KML files were created using the photographic navigation file ds953_2014-327-FA.csv. To aid navigation through the KML file, each image was assigned a sequential KML number. Table 1 (http://pubs.usgs.gov/ds/0953/html/ds953_table.html) of this report shows the KML number given to each image, the corresponding image name, and associated attributes. Each point on the Google Earth file contains the KML number, storm name, latitude, longitude, image name, geographic area, date, time, a thumbnail of the full-size photograph, and links to the full-size photographs and contact sheets.

  3. What similar or related data should the user be aware of?

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 on the GPS receivers at the beginning of each flight. Latitude, longitude, and time were collected at an interval of approximately once every 5-15 seconds. 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?
    Best attempts were made to maintain 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?
    No known issues
  5. How consistent are the relationships among the observations, including topology?
    Data presented here include the digitally collected photographs in JPEG format with Exchangeable Image File (EXIF) headers embedded with the individual photograph's location along theflightpath of a baseline coastal oblique aerial photographic survey of the coast, from Key Largo, Florida, to the Florida/Georgia border. This mission was flown on September 5-6, 2014, aboard a Cessna 182, tail number N8479S. Crew members, contracted by the USGS in St. Petersburg, Fla., include Carol McManus, Leo McManus, and George McPherson of Top Cover Virginia, LLC. Still photography was collected along the coast during this survey. Photographer: Carol McManus. GPS Data Collection - Instrument: Garmin GPSMAP 696. Data Collection Interval: Variable, every 5-15 seconds. Data File Format: ASCII Number of files created: 1. The GPS unit was used to record navigation fixes of the aircraft, not the position of the features imaged.
