Circumpolar Arctic Vegetation and Geobotanical Maps, 1982-2003

1982-2003 spatial distributions of vegetation types, geobotanical characteristics, and physiographic features for the circumpolar Arctic tundra biome. The dataset includes attributes like dominant vegetation, bioclimate subzones, floristic subprovinces, and landscape types, with some vegetation indices and biomass estimates extending through 2010. It was produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Analyzing the relationship between bioclimate subzones and dominant vegetation types across the Arctic.
• Mapping the position of the Arctic treeline and its association with landscape types and elevation.
• Studying long-term vegetation trends and biomass estimates using indices derived from satellite data.
• Assessing substrate chemistry and lake coverage patterns within different floristic subprovinces.

Strengths

• Covers the entire circumpolar Arctic tundra biome, providing a complete spatial picture.
• Includes over two decades of temporal coverage from 1982 to 2003, with some products through 2010.
• Combines multiple thematic layers including vegetation, climate, topography, and substrate data.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable from all sources.
• There is a conflict regarding the last update date: one source lists 2010-09-30, while another lists 2026-03-13.
