Description:
Abstract:
This dataset contains aerial oblique digital photos taken of the arctic landscape during low altitude photo survey transects in northwest Alaska, July 2013. Three flight transects were conducted from small aircraft over the National Park Service's Arctic Network (ARCN; Bering Land Bridge National Preserve, Cape Krusenstern National Monument, Gates of the Arctic National Park and Preserve, Kobuk Valley National Park, and Noatak National Preserve) and the U.S. Fish and Wildlife Service's Selawik National Wildlife Refuge.
Purpose:
Three aerial photo transects were conducted in July 2013, to provide photos of current conditions and prevalence of land cover types as a baseline for measuring future change, and to complement the existing grid-based sample photography of the region (Swanson 2013).
Supplemental_Information:
Extensive details of all aspects of the aerial photographic, video, and GPS data collection and processing are provided in Marcot et al. 2014.
The study area included five units of the National Park Service's Arctic Network (ACRN; Bering Land Bridge National Preserve, Cape Krusenstern National Monument, Gates of the Arctic National Park and Preserve, Kobuk Valley National Park, and Noatak National Preserve), the adjacent area of U.S. Fish and Wildlife Service's Selawik National Wildlife Refuge, and a 10-km buffer around all of these administrative units, totaling 162,868 km2 in an area spanning roughly 500 km east to west and 300 km north to south. This is also the study area for the USGS Wildlife Potential Habitat Forecasting Framework Project (WildCast) that projects effects of climate change on future land cover and wildlife habitat (DeGange et al. 2013)

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
These are aerial photos. During image processing, date and time of each photograph's EXIF (exchangeable image file format) metadata were checked for accuracy, as these data were correlated with the positions acquired from an on-board GPS and used for geotagging each photograph.
Logical_Consistency_Report: Attribute values fall within expected ranges
Completeness_Report: Data are complete. No data were omitted.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
GPS waypoints were recorded automatically at five second intervals using an i-gotU GT-120 GPS waypoint data logger mounted on each airplane's dashboard and a Garmin Oregon 550t hand-held unit (published horizontal accuracy less than 10 m).

Process_Description:
Extensive details of all aspects of the aerial photographic, video, and GPS data collection and processing are provided in Marcot et al. 2014.
Process_Date: Unknown
Process_Step:
Process_Description:
Oblique and nadir photographs and videos were shot along flight routes conducted July 16-18, 2013, totaling 17 h 46 m flight time and 2,590 km flight distance, at a mean altitude of approximately 300 m above ground level. Flight routes were selected to provide a broad representation of land cover types within each unit and to overfly specific locations of recent disturbances. Photographs were geotagged; all nadir photographs and videos were corrected for image lens distortion and appearance (increased gamma and color enhancement); oblique photographs were not corrected for appearance
Process_Date: Unknown
Process_Step:
Process_Description:
GPS waypoints were recorded automatically at five second intervals using an i-gotU GT-120 GPS waypoint data logger mounted on each airplane's dashboard and a Garmin Oregon 550t hand-held unit for backup GPS waypoint data.
Process_Date: Unknown
Process_Step:
Process_Description:
Aerial oblique images were taken with: (1) Canon Rebel 3Ti with a Sigma zoom lens (18-200mm focal length), (2) Panasonic Lumix DMC-FZ200 (24x superzoom with variable focal length), and (3) Panasonic Lumix DMC-SZ7 (10x superzoom with variable focal length)
Process_Date: Unknown
Process_Step:
Process_Description:
Raw photographs were organized into folders, renamed by flight date and camera type.
Process_Date: Unknown
Process_Step:
Process_Description:
Extensively redundant or extraneous photographs were deleted, such as time-lapse photos taken when the planes were stationary, long sequences when over deep water (e.g., over Kotzebue Sound), and other photos with no usable content.
Process_Date: Unknown
Process_Step:
Process_Description:
Date and time stamps in each photograph file's EXIF metadata were checked for accuracy and correlated to the GPS waypoints for geotagging each photograph.
Process_Date: Unknown
Process_Step:
Process_Description:
Each photograph was adjusted for color saturation and gamma, which served to highlight many details.
Process_Date: Unknown
Process_Step:
Process_Description:
EXIF metadata from all photograph files were extracted and organized in tables (CSV format). Data include photograph file and directory name, photograph date and time, camera type and settings, geotagged digital latitude and longitude, and altitude above mean sea level.
