Integrated Landscape Units (ILUM) used to create the Circumpolar Arctic Vegetation Map (CAVM). The ILUM is the union of all individual data themes used to create the CAVM. The Circumpolar Arctic Vegetation Map 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/

The map was reviewed by the CAVM mapping team.
Coverage topology was checked using the NODEERRORS and LABELERRORS commands.
Polygon boundaries were overlaid on the false-color infrared basemap and visually inspected.
False-color infrared basemap, NDVI

Digital elevation model
Calculated NDVI for 1993 and 1995 AVHRR summer scenes as:
NDVI = (Band2 - Band1)/(Band2 + Band1)
Obtained Maximum NDVI for each pixel in analysis area
