DeRaps, M.R. Kinsman, N.E.M. 2012 vector digital data, digital images Raw Data File RDF 2012-4 Fairbanks, AK, USA Alaska Division of Geological & Geophysical Surveys 2 p. http://www.dggs.alaska.gov/pubs/id/24465 In July 2012, a helicopter-based crew photographed approximately 22 miles (35 km) of shoreline near Golovin, Alaska, from the Yuonglik River delta southeast to Portage Creek. During this flight 572 oblique aerial photographs were collected and spatially referenced using a Garmin Dakota 20 handheld GPS. The purpose of this publication is to provide a spatial reference for oblique aerial photographs taken along the Golovin shoreline in July 2012. The oblique aerial imagery is intended to serve as a photographic reference of coastal features and conditions at the time of collection. One shapefile, a short manuscript that houses an index image, and the complete collection of oblique aerial photographs are provided in this publication. The point shapefile provides the spatial location where each photograph was taken. For ease of use, the oblique aerial photographs are grouped into six separate .zip file downloads. The image group divisions are each composed of approximately 100 photographs, grouped by position along the shoreline. Specific image file names and image file groups are listed in the provided point shapefile. Photography of the shoreline in the vicinity of the town of Golovin can be found in the image group golovin-shoreline-obliques-4, and the community fish camp, including extensive ice-deposited sediments from the November 2011 storm, can be found in golovin-shoreline-obliques-2. The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships. Attribute information for the layers (entity) is included in this metadata file under the "Entity_and_Attribute_Information" section. The layers are titled: >golovin-photo-points: points showing the locations of 572 oblique aerial photographs from Golovin, AK >border: outline shape of the study area 20120715 ground condition Complete None planned -163.200683 -162.841370 64.662534 64.472963 ISO 19115 Topic Category geoscientificInformation Alaska Division of Geological & Geophysical Surveys Aerial Photography Beach Deposits Coastal Coastal Erosion Geomorphology Shoreface Alaska Division of Geological & Geophysical Surveys Seward Peninsula Solomon Quadrangle Walker, J.

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 orthorectified SPOT5 satellite imagery. Oblique aerial photographs are provided for the section of Golovin shoreline from the Yuonglik River delta 22 miles southeast to Portage Creek. Photographs were taken approximately every 50 to 100 meters from a flying height of less than 500 feet above ground level (AGL). 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 Golovin shoreline was photographed from a low flying (<500 ft AGL) south bound helicopter on July 15, 2012. Coastal Hazards Program lead, Nicole Kinsman, took photographs using a hand-held Cannon PowerShot ELPH 100 HS digital camera collecting 12 Megapixel 4000x3000 (180 dpi) imagery. The photograph collection began at 6:20 pm AKST at the Yuonglik River delta and ended at 6:50 pm AKST at Portage Creek. All photos were linked to GPS tracks logged with a Garmin Dakota 20 handheld GPS. 201207 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. Each of the image files was geotagged with a GPS latitude and longitude (DD; MM: S.SSSS) that can be accessed under the image properties. 201209 Shapefile creation: Used the ArcGIS 10.1 GeoTagged Photos to Points tool to convert the GeoSetter tagged image files into xy coordinates. The coordinates were then projected into the Alaska Albers coordinate system (using NAD_1927_To_WGS_1984_7+NAD_1927_To_NAD_1983_Alaska to transform between the WGS84 and NAD83 datums) and exported as a shapefile. From there attribute fields were added and modified in order to provide additional information and organization. 201209 vector Albers Conical Equal Area 55.000000 65.000000 -154.000000 50.000000 0 0 coordinate pair 50 50 meters golovin-photo-points Albers Conical Equal Area 55.000000 65.000000 -154.000000 50.000000 0 0 coordinate pair 0.000000003 0.000000003 meters border North American Datum of 1983 Geodetic Reference System 80 6378137 298.257222 golovin-photo-points rdf2012-4-golovin-photo-points.shp Points showing the locations of 572 oblique aerial photographs from the community of Golovin Alaska Division of Geological & Geophysical Surveys FrameID Unique sequential image identifier Alaska Division of Geological & Geophysical Surveys GLV12_001 GLV12_572 ALBERS_X X coordinate of image location, Coordinate System: NAD_1983_Alaska_Albers Alaska Division of Geological & Geophysical Surveys -438133.5542 -423404.3914 meters ALBERS_Y Y coordinate of image location, Coordinate System: NAD_1983_Alaska_Albers Alaska Division of Geological & Geophysical Surveys 1642483.7406 1661817.3932 meters StillPhoto Image file name Alaska Division of Geological & Geophysical Surveys GLV12_001.jpg GLV12_572.jpg DateTime The date and time photograph was taken in the following format: YYYY:MM:DD HH:MM:SS Military Format, Alaska Standard Time Alaska Division of Geological & Geophysical Surveys 2012:07:15 18:26:26 2012:07:15 18:49:43 FileName The image group zip file package for each photograph.
