The Circumpolar Arctic Vegetation Map (CAVM) shows the types of vegetation that occur across the Arctic, between the ice-covered Arctic Ocean to the north and the northern limit of forests to the south. The CAVM team grouped over 400 described plant communities into 16 different physiognomic units based on plant growth forms. An international team of arctic vegetation scientists representing the six countries of the Arctic (Canada, Greenland, Iceland, Norway, Russia, and the United States) prepared the map. Detailed descriptions of the methods used to create the map can be found at: <http://www.geobotany.uaf.edu/cavm/>

Attribute_Accuracy_Report: The map was reviewed by the CAVM mapping team.
Coverage topology was checked using the NODEERRORS and LABELERRORS commands.
Islands and glaciers smaller than 49 square km were removed using the ELIMINATE command. Coverages were cleaned to a fuzzy tolerance of 300m. Coastlines were simplified using the GENERALIZE command (500m, bendsimplify option).
Polygon boundaries were overlaid on the false-color infrared basemap and visually inspected.
