Vegetation point-intercept (VPI) any-hit cover metric data were combined with Landsat imagery to develop fractional maps of any-hit cover for four aggregated plant functional types (PFTs); shrubs bryophytes, lichen, and herbs for the upland tundra area of the Y-K Delta, Alaska. VPI data were collected from plots in areas burned in 1971, 1985, 2005, and 2015.
Ecological field data and maps of vegetation cover spanning gradients of fire history in upland tundra are available from the Arctic-Boreal Vulnerability Experiment (ABoVE).

Example of color-infrared imagery shown alongside the corresponding semi-automated open water classification at Old Crow Flats, Alaska.
AirSWOT imagery from the 2017 Arctic-Boreal Vulnerability Experiment (ABoVE) was used to create water masks across parts of Canada and Alaska.

Study area included sites burned in 2014 and 2015 in the southeastern portion of the Northwest Territories and northern Alberta of Canada. The study area includes all 2014 and 2015 fires within a radius of approximately 300 km from Great Slave Lake.
Pre- and post-fire Landsat images were used to classify burn severity of soil organic matter across portions of arctic Canada.
