Digital Data 2018-0007
This raster dataset is a 15 m resolution grid that shows the probability of near-surface permafrost being present within each grid cell (scaled from 0 to 1). It represents a machine learning prediction based on establishing a relationship between locations where permafrost is known to be present, and a suite of predictors consisting of topographic data, satellite imagery, and climatic factors.The modelled area is restricted to northern Alberta, because in Alberta, with the exception of the Alberta Rocky Mountains and Foothills region, no permafrost exists south of 56° N latitude.
