On September 3, 2010, the USGS conducted an oblique aerial photographic survey from Breton Island to the Chandeleur Islands, Louisiana, aboard a Cessna 210 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 features 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). Purpose: To provide access to digital photographs taken as part of the September 3, 2010, baseline oblique aerial survey collected along the coast from Breton Island to the Chandeleur Islands, Louisiana, and to provide access to attribute data that documents the time and location where each photograph was taken. Supplemental_Information: For a summary of field activity 10CCH02 please see https://cmgds.marine.usgs.gov/fan_info.php?fan=10CCH02. Bounding coordinates for the oblique aerial survey are derived from the overall flight path found in the GPS data. Ancillary files included in this publication are: 10CCH02-LocationMaps.zip, 10CCH02-ProcessedNav.zip, 10CCH02-SupplementalFiles.zip, and 10CCH02-RawGPSNav.zip; in addition to the digital oblique aerial image zip files.

Browse_Graphic_File_Type: JPEG Data_Set_Credit: Funding and support for this study were provided by the USGS Coastal and Marine Geology Program (CMGP). The authors wish to thank pilot Corey Miller for his assistance with data collection. This data release benefited from the comments and review of Owen Brenner with the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC), St. Petersburg, FL. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Best attempts were made to set the camera to UTC time on the GPS receivers at the beginning of each flight. Note: Latitude and longitude positions in this data release refer to the position of the aircraft, not the position of the landmarks photographed. Refer to the Process Steps below for more detail. Logical_Consistency_Report: 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 Breton Island to the Chandeleur Islands, LA. This mission was flown on September 3, 2010, aboard a Cessna 210 aircraft, tail number NI639X. Crew members, contracted by the USGS in St. Petersburg, FL, included Karen Westphal (photography contractor) and pilot Corey Miller of Southern Seaplanes, Inc. Still photography was collected along the coast during this survey. GPS Data Collection—Instrument: Garmin GPSMAP 60CSx.Data Collection Interval: 2 Seconds. Data File Format: text, *.gdb, *gpx, *mps, *.dxf; Number of files created: 5 (Note: Only the text file is included in this data release). Completeness_Report: 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: An attempt was made to keep the same relative distance between the aircraft and the beach in order to maintain a constant field of view. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 10 Horizontal_Positional_Accuracy_Explanation: Garmin GPSMAP 60CSx accuracy is based on manufacturer specifications when available, accuracy value is provided in meters. During post-processing, the camera time was matched to the GPS time/position to determine camera location at the time of image collection. Latitude and longitude positions in this data release refer to the position of the aircraft, not the position of the landmarks photographed. The GPS unit was used to record navigation fixes of the aircraft, not the position of the features imaged. Lineage: Process_Step: Process_Description: Image Acquisition: Images were taken with a Canon Powershot S3 IS digital camera and written to internal camera cards. Image size is approximately 6 megapixels. Images in JPEG format were saved using the filename format yyyy_mmdd_hhmmssd.jpg (where the "d" signifies digital acquisition using the Canon Powershot S3 IS). The names provide information about the photograph's year, month, day, hour, minute, and second. For example, image 2010_0903_133636d.jpg was taken September 3, 2010, at 13:36:36 UTC. Best attempts were made to set the Canon Powershot S3 IS's internal clock to within 1 second of UTC at the beginning of the flight.
