Mapping Surface Waters from ABoVE

Open surface waters for a location in Canada

Orthomosaic imagery taken from a Beechcraft Super King Air B200 aircraft traveling north of the Mackenzie River in the Dehcho Region of Canada.

NASA's 2017 ABoVE airborne campaign provides high-resolution, georeferenced, three-band orthomosaics of digital imagery to validate maps of Arctic surface water extent.

A new dataset from NASA's ABoVE campaign estimates effects of climate on Dall sheep populations throughout Alaska and northwestern Canada.

Maximum NDVI from the ABoVE Campaign

Long-term maximum NDVI measured 2002-2017

Long-term maximum NDVI for the ABoVE study area covering the years 2002-2017.

Annual maximum NDVI estimates from 2002-2017 are available for most of Alaska and the Yukon Territory.

Field site locations that correspond to the flight tracks of the 2017 ABoVE Airborne Campaign have been published.

High-Resolution Permafrost Maps for Western Alaska

Map of permafrost presence and locations of elevation extremes.

High-resolution elevation maps, based on LiDAR, were used to model the distribution of permafrost across the Y-K Delta of Alaska. The map insets show detail for areas of relative high elevation (left) and low elevation (right).

Scientists with NASA's ABoVE field campaign modeled the distribution of permafrost across the Yukon-Kuskokwim Delta of Alaska.
