LANDFIRE's (LF) Existing Vegetation Cover (EVC) represents the vertically projected percent cover of the live canopy layer for a 30-m cell.
EVC is generated separately for tree, shrub, and herbaceous cover lifeforms using training data and other geospatial layers. Percentage tree, shrub, and herbaceous canopy cover training data are generated using plot-level ground-based visual assessments and lidar observations.
LF uses EVC in several subsequent layers, including the development of the fuel layers.
Modeling Dynamic Fuels with an Index System (MoD-FIS)- refined EVH classification based upon current estimates of EVC from Landsat imagery for the current growing season.
The comma separated value (CSV) file used for the raster attribute table is included in the LF product download in database file (DBF) format.
(Why is the CSV important?)
