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 March 27, 1998, the USGS conducted an oblique aerial photographic survey from Fenwick Island State Park, Delaware, to Corolla, North Carolina, aboard a U.S. Coast Guard HH60 Helicopter at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. This mission was conducted to collect data for assessing incremental changes in the beach and nearshore area and can also be used as a baseline 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 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. All image times are recorded in Coordinated Universal Time (UTC).
Purpose:
To provide access to digital photographs taken as part of the March 27, 1998, baseline oblique aerial survey collected along the coast from Fenwick Island State Park, Delaware, to Corolla, North Carolina, and to provide access to attribute data that documents the time and location where each photograph was taken.
Supplemental_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. The clock of the Compix Titler unit was also set to UTC at the same time. Human error during transcription of geographic position and time from the video is possible; however, no obvious errors were observed. Latitude, longitude, and time were linearly interpolated from known navigation (collected once every 30 seconds) and image time stamps (collected once every minute). Note: Latitude and longitude positions in the navigation files 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 in this publication include the digitally scanned analog slide photographs in JPEG format with the Exchangeable Image File (EXIF) headers embedded with the individual photograph's location along the flight path of the baseline coastal oblique aerial photographic survey of the coast, taken from Fenwick Island State Park, Delaware, to Corolla, North Carolina. This mission was flown on March 27, 1998, aboard a U.S. Coast Guard HH60 Helicopter, tail number HH6002 aircraft. Crew members of the USGS in St. Petersburg, FL, included M. Dennis Krohn, Russell Peterson, and Dana Wiese; and Lt. Tam Fletch (pilot) of the U.S. Coast Guard. The GPS receiver used to provide navigation to the video titler unit was a Trimble Centurion, which is accurate to within 100 feet. Independent of all other equipment, a Rockwell Collins Precision Lightweight Global Positioning System Receiver unit, also accurate to within 100 feet, recorded navigation fixes. 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. Still photography was collected along the coast during this survey. GPS Data Collection—Instrument: Trimble Centurion and Rockwell Collins Precision Lightweight Global Positioning System Receiver (PLGR), Data Collection Interval: 30 Seconds, Data File Format: Text, Number of files created: 1; Trimble data: recorded on video tape, PLGR data: text file, Computer/Software: none. The GPS units were used to record navigation fixes of the aircraft, not the position of the features imaged.
Completeness_Report:
During the flight film roll number four was incorrectly loaded into the camera. As a result, there is no data for roll number 4 in this data set. When the error was discovered, the aircraft backtracked and collection began again with film roll number 5. 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.

Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 30
Horizontal_Positional_Accuracy_Explanation:
Trimble Centurion and Rockwell Collins PLGR GPS accuracy is based on manufacturer specifications when available. 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.

Process_Step:
Process_Description:
Image Acquisition: Photographs were taken with two Nikon F3 cameras, each with a fixed 50-millimeter lens and a Skylight filter. One camera shot the odd-numbered film rolls, and the other camera shot the even-numbered rolls. Both cameras were equipped with a Nikon MF-14 data back. Rolls were numbered by hand in the air. Film used was Kodak Ektachrome E100G. Commonly used shutter speeds were 1/250 seconds or 1/125 seconds. A constant shutter speed was attempted but may vary if there was a noticeable change in light levels. The f-stop was changed to compensate for changes in light levels. The Nikon MF-14 data back added day of the month, hour, and minute (UTC) to the lower right-hand corner of the photo. All photographs were taken from the the open door of the aircraft. Independent of all other equipment, a Rockwell Collins PLGR GPS recorded navigation fixes, at a 30-second interval, acquired from a National Marine Electronics Association (NMEA) string during the flight. A Compix Titler unit provided video subtitles that include latitude, longitude, and time (Hour:Minute:Second). Navigation was provided to the video by a Trimble Centurion GPS receiver, and time was provided by the titler unit's internal clock, which had been synchronized with UTC time. The cameras' images are denoted by a "r###s##" in the filename. The images are labeled with the following filename format: yyyy_mmdd_r###s##.jpg, where yyyy denotes the year, mmdd denotes the month and day, r### is the roll number and s## is the slide number of the image. For example, image 1998_0327_r001s03.jpg was taken March 27, 1998, the first roll of the flight, the third slide.

Process_Description:
Slide Scanning and Processing: Slides were scanned using a Nikon Super CoolScan 5000 scanner and Nikon Scan 4 software. The slides were scanned using Digital Image Correction and Enhancement (ICE) technology at a resolution of 3,000 dots per inch (DPI) and files were saved as 18.6-megabyte tagged image file format (TIFF) images. The TIFF images were then converted to JPEG images at a resolution of 3000 dots per inch using Adobe Photoshop CC. ICE technology automatically removes artifacts, such as dust and scratches from scanned images. Only JPEG images are included in this data release. The photograph names provide information about the photograph's year, date, roll number, and slide number. For example, slide 1998_0327_r030s01 was taken March 27, 1998, and is the first slide for roll 30. Slide names (year_monthday_roll numberslide number) and time (hour, minute) were manually entered into a Microsoft Excel Ver. 15 spreadsheet. A Nikon MF-14 data back marked the time each photograph was acquired on the lower right corner of the image in day, hour, and minute format. It is assumed, for the purposes of location, that the photographs were taken at a constant rate during any given minute of flight. To assign a time value in seconds to each photograph, the number of photographs taken during each minute was evenly distributed across those 60 seconds. For example: if 15 photographs were taken during minute 19:00, researchers assumed that a picture was taken every 4 seconds. The photographs were then assigned the time values 19:00, 19:04, 19:08, and so on. It should be noted that the positions assigned to each photograph are an estimate of the aircraft position, not the location of the landmark photographed. Photos were then reviewed in Google Earth and adjustments to their positions were made by hand to compensate for pauses during acquisition. During this flight the photographer did not make an effort to get overlapping imagery.
