DeRaps, M.R. Kinsman, N.E.M. 2011 vector digital data, digital images Raw Data File RDF 2011-5 Fairbanks, Alaska USA State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys 3 DVDs http://www.dggs.alaska.gov/pubs/id/23143 In July 2011, a helicopter-based crew photographed approximately 180 miles of shoreline along the eastern edge of Norton Sound, from Cape Denbigh to south of Unalakleet, AK. During this flight 2,180 oblique aerial photographs were collected and spatially referenced using a Garmin Dakota 20, handheld GPS. The communities of Unalakleet and Shaktoolik lie along the flight-line of this project. The purpose of this publication is to provide a spatial reference for oblique aerial photographs taken along the Eastern Norton Sound shoreline in July 2011. The oblique aerial imagery is intended to serve as a photographic reference of coastal features and conditions at the time of collection. One shapefile, an Excel file, and the complete collection of oblique aerial photographs are provided in this publication. A point file (replicated in both Excel and shapefile formats) provides the spatial location where each photograph was taken. For ease of use, the oblique aerial photographs are grouped into 19 separate .zip file downloads. The image group divisions are composed of approximately 100 photos and are grouped by general shoreline position and characterization. Image file names and image file groups are listed in the point files. Photography of the shoreline in the vicinity of Unalakleet and Shaktoolik can be found in the image groups norton-sound-shoreline-obliques-15 and norton-sound-shoreline-obliques-07, respectively. The DGGS metadata standard extends the FGDC standard to include several elements that are required to facilitate internal data management. These elements, referred to as 'layers', group and describe files that have intrinsic logical or topological relationships. This dataset is described by one layer titled: >norton-sound-photo-points Points showing the locations of 2180 oblique aerial photographs from eastern Norton Sound (these points are provided in both .xlsx and shapefile formats) 20110730 ground condition Complete None planned -161.533151 -160.762814 64.557607 63.697326 ISO 19115 Topic Category geoscientificInformation None Aerial Photography Coastal Coastal Erosion Beach Deposits Geomorphology Shoreface None Norton Bay Quadrangle Norton Sound Unalakleet Quadrangle None Holocene The dataset(s) is (are) available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

The clocks of both the camera and GPS were synchronized in order to link the camera's photographs with the spatial location provided by the GPS. The following logical consistency test was performed: photograph content were checked against the photo's geospatial location on LANDSAT imagery. Oblique aerial photographs are provided for the section of Norton Sound shoreline from approximately one mile North of Shaktoolik, AK to one mile South of Unalakleet, AK. There are two locations where the flight path and associated photographs deviate from the coast. The first location is within the community of Shaktoolik, caused by the re-fueling of the helicopter. The second location, just North of Unalakleet, was caused by reduced visibility that forced the pilot to circle until he gained special IFR clearance. The possible flight lines near Unalakleet were restricted due to reduced visibility, therefore photos are taken from lower altitudes and closer to the shoreline in this segment. The Unalakleet airport reported 2.5 to 5 mile visibility during the flight window for image collection. Accuracies of photo points are dependent on the handheld GPS units used to track the helicopter's position. According to the Garmin manual, typical horizontal accuracies for the Dakota 20 are less than 10 m. Acquisition of Oblique Aerial Images: The Norton Sound shoreline was photographed from a low flying south bound helicopter on July 30, 2011. The crew employed a hand-held Cannon PowerShot ELPH 100 HS digital camera to collect 12 Megapixel 4000x3000 (180 dpi) imagery. The photograph collection began at 9:00 am AKST north of Shaktoolik and ended at 12:00 noon AKST south of Unalakleet. All photos were linked to GPS tracks logged with a Garmin Dakota 20 handheld GPS. 201107 GPS and camera clock synchronization: The clocks of both the camera and GPS were synchronized using GeoSetter software. This step was necessary in order to link the camera's photographs with the spatial location provided by the GPS. 201110 Shapefile creation: Used ArcGIS 10 to convert the GeoSetter created KMZ files to a shapefile with location, time, and photo identifier information. 201110 0 Vector Albers Conical Equal Area 55.000000 65.000000 -154.000000 50.000000 0 0 row and column 0.002048 0.002048 meters norton-sound-photo-points North American Datum of 1983 Geodetic Reference System 80 6378137 298.257222 norton-sound-photo-points rdf2011-5-norton-sound-photo-points.shp Points showing the locations of 2180 oblique aerial photographs from eastern Norton Sound Alaska Division of Geological & Geophysical Surveys FrameID Unique sequential image identifier Alaska Division of Geological & Geophysical Surveys NS11_0910 NS11_3099 ALBERS_X X coordinate of image location, Coordinate System: NAD_1983_Alaska_Albers Alaska Division of Geological & Geophysical Surveys -362686.374935 -332015.92444 meters ALBERS_Y Y coordinate of image location, Coordinate System: NAD_1983_Alaska_Albers Alaska Division of Geological & Geophysical Surveys 1543901.64244 1638796.72345 meters StillPhoto Image file name Alaska Division of Geological & Geophysical Surveys NS11_0910.jpg NS11_3099.jpg DateTime_s The date and time photograph was taken in the following format: YYYYMMDDHHMMSS, Alaska Standard Time.
