Parent Layer: Vegetation

Name: ExistingVegCentralValley1998_2007_v1

Display Field: ECOREGION_DOMAIN

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This Existing Vegetation (Eveg) polygon feature class is a CALVEG (Classification and Assessment with LANDSAT of Visible Ecological Groupings) map product from a scale of 1:24,000 to 1:100,000 for CALVEG Zone 5, the Central Valley. Source imagery for this layer ranges from the year 1998 to 2007. 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 included in the database to meet national standard requirements. Mapping standards 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 (CWHR).For a description of CALVEG and a data dictionary for codes in this database, go to the Existing Vegetation Layer Description at http://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5365219.For an index of CALVEG zones, go to http://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192and select the link called Existing Vegetation Tiles Index.For a CALVEG mapping status by scale and year, go to http://www.fs.usda.gov/detail/r5/landmanagement/resourcemanagement/?cid=stelprdb5347192and select the "Existing Vegetation Mapping Status by Year, Scale and Project" link. *******Note: This layer is comprised of "multi-part" features, spatially separate polygons sharing the same attributes and stored as a single feature. A group of islands could be represented as a multi-part polygon feature. This allows for reduction in the size of the database and portability across a network. For analysis purposes however, it is wise to select a smaller area of interest and break apart features using the "Multipart To Singlepart" tool in ArcGIS. In its entirety, a "single-part" format of this feature class can potentially be more than one million polygons.
