Mission of the Arctic Geobotany Center
- Explore and understand Arctic geoecological relationships and dynamics at local to global scales;
- Promote interdisciplinary Arctic science research and collaboration;
- Investigate Arctic land-use and conservation issues through geoecological research;
- Educate and train students in Arctic vegetation science field skills and analysis; and
- Disseminate information about our research to educators, students, scientists and the general public.

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.
