Abundant ground-based information will be necessary to inform the planned Arctic-Boreal Vulnerability Experiment (ABoVE) activities. The Atlas is comprised of archives of maps and plot-based vegetation data, and associated information. The Map Archive contains map products at several scales and numerous themes. The maps range from detailed geoecological maps, which are polygon-based integrated terrain maps at relatively fine scales, to raster-based map products derived from satellite data and digital elevation models. The Vegetation Plot Archive contains vegetation-plot data, associated environmental data, and other related information from over 3,000 plots in Arctic Alaska.
