Description:

Abstract:

This dataset contains aerial nadir video segments from a GoPro Hero3 Black Edition (focal length 2.77 mm; 60 frames per second) of the arctic landscape during low altitude photo survey transects in northwest Alaska, July 2013. Two flight transects were conducted from small aircraft over the National Park Service's Bering Land Bridge 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)

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:

Raw video segments were organized into folders, renamed by flight date and camera type.

Process_Date: Unknown

Process_Step:

Process_Description:

Some video segments were corrected for lens distortion to adjust for their wide-angle distortion. In those cases, the uncorrected video is also provided.
