Description:
Abstract:
This existing vegetation tile is a recently completed CALVEG (Classification and Assessment with LANDSAT of Visible Ecological Groupings) map product at a scale primarily of 1:100,000 within CALVEG Zone 5 (Central Valley). The CALVEG classification system was used for vegetation typing and crosswalked to other classification systems in this database. 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.

For more information refer to the GIS layer description, Existing Vegetation Mid Level Map by the USDA Forest Service, Pacific Southwest Region, at http://www.fs.fed.us/r5/rsl/projects/frdb/layers/ev_mid.html. 

NAMING CONVENTION 
For example - EvegTile06A_03_04_24k_v2: 
<06A>_03_04_24k_v2 - Tile number (see tile index called Calveg Tiles_Ecoregions at http://www.fs.fed.us/r5/rsl/clearinghouse/gis-download.shtml) 
06A_<03_04> - source year(s) of data i.e. 2002, 2003
06A_03_04_<24k> - map scale standard i.e. 1:24,000 (or <100k> for 1:100,000)
06A_04_24k_<v2>- version number
Purpose:
The goal of this project is to create a meaningful and usable seamless dataset for the Central Valley zone combining currently mapped US Forest Service lands data with the best available data outside FS lands.

PROJECT NAME:  Geobook - Central Valley
PROJECT DATE:  1/2009 - 7/2009 


PHASE 1 - 
(tlindemann, hgordon, rjwarbington)
Data was obtained from multiple sources,  at various map and temporal scales, for areas outside US Forest Service lands and crosswalked to the CALVEG classification system. One source (Suisun Marsh) was especially detailed and displayed a one-to-many relationship with CALVEG in which the most appropriate Regional Dominance Type was chosen for this project.  Other sources had greater generality than that of CALVEG, such as Land Cover geospatial databases.
For each source featureclass, a frequency was run on pertinent fields in order to determine the number of unique combinations that occurred. RSL staff reviewed, edited and cross-walked each agency's vegetation dataset into the CALVEG classification system.  The following fields of the standard Existing Vegetation template were populated via customized cross-walks:
COVERTYPE
REGIONAL_DOMINANCE_TYPE_1
REGIONAL_DOMINANCE_TYPE_2
USGS_ANDERSON1
USGS_ANDERSON2
WHRSIZE
WHRTYPE
WHRDENSITY
SOURCE
For areas where no data was found (holes), multi-resolution segmentation was applied to 10-m Spot imagery to achieve delineations of vegetation polygons. These features were then photo-interpreted using the 2005 NAIP imagery. 

PHASE 2
(blee, Sanborn)
For forested only lands (non-urban and non-agricultural) that were identified, NLCD Continuous Tree Cover was integrated using mean percentage in order to update structure values. Low estimates of tree cover values were used to identify shrubs and the higher percentages were used to populate TOTAL_TREE_CFA (cover from above), HDW_CFA and CON_CFA. A size classification raster was created and regionalized by majority to populate the OS_TREE_DIAM1. Photo interpretation with NAIP imagery was used to fill in areas with missing structural attributes or where errors were highly probable.
For the non-forested lands, the USDA Cropland layer was integrated. Photo interpreted data was not overwritten. Cross-walks were created to refine the USGS_ANDERSON2, REGIONAL_DOMINANCE_TYPE 1 & 2, COVERTYPE and WHRTYPE of the non-forested lands.
The forested and non-forested areas were integrated and topology errors corrected.

PHASE 3
(cclark, GD)
The feature class was subset into CALVEG tiles, populating ECOREGION DOMAIN, DIVISION, SECTION, SUBSECTION, TILE and CALVEGZONE fields in the process.
WHRLIFEFORM was populated based on a WHRTYPE crosswalk values. WHRSIZE was populated using another crosswalk from  OS_TREE_DIAM1. 
PROD (productivity) field was crosswalked based on the CALVEG_FOREST_TYPE_XWALK table, linking to REGIONAL_DOMINANCE_TYPE_1. 
The final phase incorporated waterbodies (lakes, rivers, reservoirs) where missing and the coding was changed on existing polygons from "Water (General)" to more detailed coding. Where water polygons were missing or spatially inaccurate based on photo interpretation, NHD (National Hydrography Dataset) polygons were "burned" in and coded to CALVEG standards. Polygons over 2 1/2 acres not brought over from NHD and still coded as "Water (General)" were photo interpreted and coded. Remaining polygons under 2 1/2 acres (MMU) were eliminated.
