Description: This <Forest> National Forest Existing Vegetation (Eveg) polygon layer is a recently completed <year> Classification and Assessment with LANDSAT of Visible Ecological Groupings (CALVEG) map product at a scale of 1:24,000, which updates and revises the <year> data for the National Forest administrative areas, including private land inholdings.The CALVEG classification system was used for vegetation typing and crosswalked to other classification systems in this database. USGS Land Use / Land Cover Anderson 1 classification system is now included in the database to meet national standard requirements. Mapping standards now meet requirements of the USDA Forest Service as defined by the FS GIS data dictionary, FGDC Vegetation standards and the FS Existing Vegetation Classification and Mapping Technical Guide. Regional add-ons are retained for crosswalking to the California Wildlife Habitat Relationship System.
