The Raster Circumpolar Arctic Vegetation Map (Raster CAVM) maps 16 vegetation types, glaciers, saline water, and freshwater at 1-km resolution. It builds on the strengths of the original CAVM, using the same legend, extent and projection, while providing a finer spatial resolution, raster format, and improved mapping of Arctic vegetation.
