Title:
Baseline coastal oblique aerial photographs collected from Navarre Beach, Florida, to Breton Island, Louisiana, September 1, 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 1, 2014, the USGS conducted an oblique aerial photographic survey from Navarre Beach, Florida, to Breton Island, Louisiana, aboard a Maule MT57 aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore (Figure 2, http://pubs.usgs.gov/ds/0952/html/ds952_fig2.html). This survey was flown to collect data for assessing incremental changes since the last survey, flown July 2013, 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 and aircraft do not indicate the location of the feature in the images (see the Navigation Data page for additional details, http://pubs.usgs.gov/ds/0952/html/ds952_nav.html). These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. CSV: Comma separate values files representing table information collected during the flight. JPEG: Images can be opened directly with any JPEG-compatible image viewer. The survey's full-size photographs are divided into ?two ?areas. KML: ds952_2014-?326-FA.kml has? 1,111 photographs. TXT: Text files representing the navigation files, FACS log, metadata and readme files collected during and after the survey. KML: The KMLs provided may be viewed with Google Earth (http://www.google.com/earth/download/ge/agree.html). 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/0952/html/ds952_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 saved to internal camera cards. Image size is approximately 22 megapixels. Images in JPG format were saved using the filename format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using a Canon EOS 5D Mark III). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2014_0901_133636d.jpg was taken September 1, 2014, at 13:36:36 UTC. Best effort was made to set the Canon EOS 5D Mark III'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, USGS, GPS data and image files were used to generate a comma-separated value (CSV) file containing latitude, longitude, and time records for each image. This processed navigation file was saved as a CSV file, ds952_2014-326-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 comma-separated value (CSV) files 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 shapefile were used to produce the JPEG maps included in this report. These shapefiles are not included in this report. Person who carried out this activity:

  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 time on the GPS receivers at the beginning of each flight. Latitude, longitude, and time were collected at an interval of approximately once every 5 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 EXIF headers embedded with the individual photograph's location along the flight path of a baseline coastal oblique aerial photographic survey of the coast, from Navarre Beach, Florida, to Breton Island, Louisiana. This mission was flown on September 1, 2014, aboard a Maule MT57, tail number N5500K. Crew members, contracted by the USGS in St. Petersburg, Fla., include Amy Hartsfield (photography contractor) and pilot, Ian McIntyre, of Amy & Company, Inc. Still photography was collected along the coast during this survey. GPS Data Collection - Instrument: Garmin GPSMAP 196. Data Collection Interval: 1 second. Data File Format: Text. Number of files created: 1. Computer/Software: none. Computer: none The GPS unit was used to record navigation fixes of the aircraft, not the position of the features imaged. No photographs were taken during the following 5-minute segment due to transiting between locations: ds952_2014_0901_183500.html.
