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 9-10, 2008, the USGS conducted an oblique aerial photographic survey (during Field Activity Number [FAN] 08ACH05) from Calcasieu Lake, Louisiana, to Brownsville, Texas, aboard a Cessna C-210 aircraft at an altitude of 500 feet (ft) and approximately 1,000 ft offshore (Figure 2, https://pubs.usgs.gov/ds/0991/html/ds991_fig2.html). This mission was flown to collect data for assessing incremental changes in the beach and nearshore area 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, https://pubs.usgs.gov/ds/0991/html/ds991_nav.html). These photographs document the configuration of the barrier islands and other coastal features at the time of the survey. 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 UTC. Table 1 (https://pubs.usgs.gov/ds/0991/html/ds991_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.

Purpose:

To provide access to digital photographs taken as part of the September 9-10, 2008, baseline oblique aerial survey collected along the coast, from Calcasieu Lake, Louisiana, to Brownsville, Texas, and to provide access to attribute data that document the time and location of where each photograph was taken.

Supplemental_Information:

For a summary of field activity 08ACH05 please see http://cmgds.marine.usgs.gov/fan_info.php?fan=08ACH05. Bounding coordinates and start and end times for the Data Series were derived from the overall flight path included in the raw GPS data. Ancillary files included in this publication are ds991_08ACH05_0909_gpsmap60c.txt, ds991_08ACH05.csv, and ds991_08ach05.kml, in addition to the digitized oblique aerial image files.

HTML Creation: 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.

Geospatial Processing: Spreadsheets containing the GPS data were edited using Microsoft Excel 2011 and saved as a comma-separated value (CSV) file to ensure compatibility with ArcGIS software. The latitude/longitude data from the CSV navigation file, called XSTORMS.h20080909_photographs, were used to produce Environmental Systems Research Institute (Esri) shapefiles using ArcGIS 10.1. These shapefiles were used to produce the JPEG maps included in the Data Series; however, the shapefiles were not included in the report.

Google Earth file creation: The Keyhole Markup Language (KML) file were created using the photographic navigation file ds991_08ach05.csv. The USGS is the originator of all other layers. To aid navigation through the KML file, each image was assigned a sequential KML number. Table 1 (https://pubs.usgs.gov/ds/0991/html/ds991_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.
