Description:
Abstract:
GPS waypoints delineating the flight paths for low altitude transects from a i-got-u GPS unit. Transects were conducted from small aircraft over the National Park Service’s Arctic Network (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 in northwest Alaska. Positions were collected at five second intervals.
Purpose:
Provide images 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.

Description_of_Geographic_Extent:
The study area included five units of the National Park Service’s Arctic Network (Bering Land Bridge National Preserve, Cape Krusenstern National Monument, Gates of the Arctic National Park & 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)
