The VMap database consists of four primary spatially explicit

attributes that include descriptions of 1) lifeform, 2) tree canopy cover class, 3) tree size class,

and 4) tree dominance type. These attributes can be mapped and used to support mid and baselevel analysis and planning. VMap uses the Region 1 Existing Vegetation Classification System

(Barber et al. 2009) in its map unit design. This system defines the logic for grouping entities by

similarities in their floristic characteristics. VMap products are derived using remote sensing

technology, and are based on a combination of airborne imagery and a nationally available

digital topographic and climatic data.
