Summary

****** NOTE: DRAFT METADATA AND PRELIMINARY DISTRIBUTION FORMAT. Check back in first quarter 2014 for availability of final distribution package. ******* Vegetation map for the Santa Monica Mountains and Vicinity. These data were created through field vegetation classification and air photo interpretation as part of the NPS Vegetation Inventory Program (VIP). The NPS Vegetation Inventory Program uses the National Vegetation Classification Standard (NVCS), a classification system well integrated with the major scientific efforts in the taxonomic classification of vegetation. The classification system is a Federal Geographic Data Committee (FGDC) standard for the physiognomic levels (coarser detail). Work continues on the floristic levels (fine detail) through both the FGDC Vegetation Subcommittee and the Ecological Society of America Vegetation Panel. The map class themes represent NVCS natural/semi-natural vegetation communities. Maps are produced in Universal Transverse Mercator (UTM), NAD83 datum with a 1:24,000 scale and a minimum mapping unit of 0.5 hectares. The vegetation maps must meet the National Map Accuracy Standards for positional accuracy and the minimum class accuracy goal across all vegetation and land cover classes of 80 percent.This is baseline information for use in managing and protecting resources of the Santa Monica Mountains National Recreation Area.

Description

****** NOTE: DRAFT METADATA AND PRELIMINARY DISTRIBUTION FORMAT. Check back in first quarter 2014 for availability of final distribution package. ******* This vector polygon dataset represents the vegetation for the Santa Monica Mountains National Recreation Area and immediate vicinity. Vegetation units were determined by stereoscopic examination of color air photos flown 7/2001, by AIS, Redlands, CA, in collaboration with Santa Monica Mountains National Recreation Area, National Park Service, Department of the Interior (NPS-SAMO). Vegetation classification developed by Todd Keeler-Wolf, State Vegetation Ecologist, and NPS-SAMO. Classification and air photo interpretation based on approximately 6,000 ground-based observations made by CNPS Rapid Assessment protocols. Vegetation classification is in accordance with standards of the U. S. National Vegetation Classification. This dataset is demonstrated to be in substantial compliance with U. S. National Map Accuracy Standards. Note that the accuracy of an individual class will vary from the overall accuracy figures, and that due to limited resources not all classes were fully evaluated using field data. Refer to the accuracy assessment section of the supporting documentation for detailed information and type specific accuracy results (pending).

Supplemental information
The U.S. Geological Survey (USGS) and National Park Service (NPS) formed a partnership in 1994 to map the vegetation of United States National Park system units using The Nature Conservancy's National Vegetation Classification, a standard for reporting vegetation information among federal agencies (Grossman et al. 1998). Goals of the projects include providing baseline ecological information to resource managers in the parks; putting the data into regional and national contexts; and providing opportunities for future inventory, monitoring, and research activities. Each park is developing a vegetation map follows a standardized field sampling and vegetation classification protocol to document the various vegetation types found in that park. This information is used by photo-interpreters to delineate polygons of vegetation communities, which are subsequently subjected to an accuracy assessment process (USGS 1994). The final products consist of a vegetation map, descriptions of each vegetation type, a key to each type, and all related data and metadata files (original field forms, plot database, accuracy assessment points, etc.). This report presents the work at the Santa Monica Mountains National Recreation Area (SAMO) and environs conducted from 2001 to 2005. The following publications contain more detailed information about the vegetation units shown in this map, and the methods of the vegetation mapping program: Keeler-Wolf, T., and J. M. Evans. 2006.

Description
Data were processed and put on GIS data server at SAMO. Steps included: 1) Removed unmapped polygons from quadrangle boundaries (Polygons where PI = 0) 2) Removed ocean polygons. 3) Removed extraneous fields: QQUAD_NAME, QQUAD_ABBR, SYM, AREA, PERIMETER 4) Renamed (redefined using ET GeoWizards 9.7) original coverage fields FINALVEG_ to COVER_NO and FINALVEG_I to COVER_ID. 5) Renamed (redefined using ET GeoWizards 9.7) fields PI to PI_NUM and MOD to QQUAD. 6) Added and populated HECTARES and ACRES fields using calculate geometry. 7) Filled in missing quarter quadrangle names (QQUAD field). 8) Joined landuse descriptions (Landuse_Tab.dbf) to attribute table based on LUCODE and populated LUTEXT field. Note that in original delivery only 3,926 records had descriptions in LUTEXT and 196 of these were incorrect (codes were updated, but not text). These were erased and the field was repopulated. 9) Added vegetation associations and alliances to attribute table by joining Assoc_Alliance.tab to attributes based on PI_NUM. Fields added were Class_NUM, Alliance, Assoc, C_Alliance, and C_Assoc. 10) Edited metadata in ArcCatalog and added NPS information using NPS Metadata Editor Ver. 1.1. 11) Copied to GIS server. Still to do: 12) Currently checking vegetation lookup table (Assoc_Alliance.tab) for errors and will replace vegetation descriptions if necessary.

Description
Fixed polygon error described in the correspondance between Kendra Sikes, SAMO Biotech and Ed Reyes, AIS from 2/20/2008 (see copy below). Hi Ed, For the first time I've come across something in the GIS database > that appears to be a coding error. We wanted to check that this is a > mistake and that we can just make a correction to the database. It is on > photo overlay 10-11, which came with the last set of overlays in August > (though it does say "preliminary" on it). The polygon is at NAD83 335640E > 3772300N. On the overlay it is marked as 1118, which when we AA'd it, was > the correct vegetation type. In the database it is marked as 20650. > Actually in the version I am looking at, which has had some dissolves done > to it, the polygon is joined to an adjacent polygon by a corner, and when > you click on it to identify it, both polygons light up. Maybe its a > topology problem. Anyway, I'm sure I can get one of the GIS people to fix > it... once you confirm that it is an error. Thanks. - Kendra Hi Kendra, I checked the situation out. It looks like the overlay is correct and there should be two polygons not one. The long arm should be coded 2065 with a density of 1, the lower polygon is 1118 with a density of 3. Where the two come together there is a squeeze that did not get closed in the database, so one polygon was formed instead of two. Please close the gap by getting rid of the corridor between the two sections. The 2572 polygon should then touch the 1452 polygon, making the 2065 and 1118 not touch each other at all. I hope I have conveyed this so it makes sense to you. Let me know. Thanks, Ed

Description
Between March 2013 and September 2013 completed the following process steps: 1. Copied most recent files to J:\data\plants\vegetation\2007vegmap\Spatial_Data\Processing_AprMay2013\ 2. Renamed veg map to Vegetation_Rev0413.shp 3. Added Map_ID field (long, 8) and calculated to FID+1 (this will be unique ID for original vegmap polygons) 4. Dissolved on PI_NUM, DENSITY, UTDENSITY to PINumDensity_dslv.shp 5. Added AAMap_ID field to PINumDensity_dslv.shp and calculated to FID+1 (this will be unique ID for AA polygons) 6. Joined PINumDensity_dslv.shp attributes to AAdB_Locations_and_Type_Corrections.shp with spatial join to create AA_MapPolys.shp. Deleted joined FIDs and other unneeded fields. (Also delete PI_NUM, DENSITY, UTDENSITY??). Provides AADB_ID to AAMap_ID link. Exported attributes to AAdb_AAMapXref.dbf. 7. Joined PINumDensity_dslv.shp attributes to Vegetation_Rev0413.shp with spatial join to create Veg_AAPolys.shp. Provides Map_ID to AAMap_ID link. Exported table as text and then to Map_AAMapXref.dbf. Deleted all but Map_ID and AAMap_ID fields. 8. Joined Map_AAMapXref.dbf (MapID) and then AAdb_AAMapXref.dbf (AAMap_ID) to Vegetation_Rev0413. Exported as Vegetation_Rev0413b. Checked to ensure no repeated AAMap_IDs or AAdb_IDs. 9. The red italic text below is from initial round of processing. All 18 points were deleted from the AA database and AAdB_Locations_and_Type_Corrections.shp and processing redone from beginning (#1 above). This file describes most recent data. Why do two of the AA points (from AAdB_Stand_Locations) fall in the same polygon in the dissolved veg (PINumDensity_dslv)? 18 polygons contain 2 points, so there are a total of 2189 AA polys and 2207 AA points. This is an error. For 8 of these polygons there are two different field calls. Tony is investigating this. The other 10 contained points from mismatched data sheets where original ID was lost, then were assumed to match other IDs (which already had points). 10. Everything needed is in Veg_Rev0413b.shp 11. Need to add AAMap_ID to Access database. 12. Reorganized attribute table and saved as Veg_Rev0413d.shp. 13. Calculated AA_Num = PI_Num except for AA corrections which were calculated based on corrected class. (Note that corrected AA number is final map class not PI number. However, to ensure that we can join map class table to update class, the corrections are reflected in AA_Num field with a "1" in AA_Change field.) 14. Added two "PI_Nums" to PICodeToFinalCode_XRef.tab for changed records that did not originally have a PI number (AA_Num = 25300, 25900, 48100) so join would work properly. 15. Fixed typo in AA_Num for samo2444 (should be 21500) in both AAdB_Locations_and_Type_Corrections.shp and Veg_Rev0413d.shp. Other veg versions will be wrong. 16. Joined PICodeToFinalCode_XRef.tab to Veg_Rev0413d.shp and compared new and old PI_Nums, Map classes, and common names to find any errors. Calculated Map_Class from joined table. Rationale: Restructuring of data needed to add information from accuracy assessment, track changes, organize in preparation for public distribution, document new fields and changes, update metadata, and create version based on accuracy assessment for public.

Overview Description
Entity and Attribute Overview
Vegetation classes based on Vegetation Classification of the Santa Monica Mountains National Recreation Area and Environs in Ventura and Los Angeles Counties, California (see full citation). Final map classes represent mappable types from the classification along with some synthetic mapping units (typically urban or disturbed types not found in the classification). Accuracy Assessment was based on these final map classes. Attributes also include land use based on 2003 GIS database from Southern California Association of Governments. See lut_Land_Use for code descriptions. Land use was updated by photo interpreters for the project and will differ somewhat from original dataset. Other attributes include density and urban tree density (see PI report for more information), and various identifiers for linking associated tables and information. Note: certain fields have been added by the Department of Fish and Game's Vegetation Classification and Mapping Program. These include crosswalks to the Wildlife Habitat Relationships and CalVeg classification systems, Global and State Ranks, CaCode and the fields relating the mapping units to the National Vegetation Classification System as it is described for California in the 2nd edition of the Manual of California Vegetation
