Yosemite National Park, Division of Resources Management and Science, Physical Sciences and Landscape Ecology 20120601 vector digital data https://apps.wildlife.ca.gov/bios/ https://irma.nps.gov/DataStore/Reference/Profile/2186173 ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/200_299/ds200.zip This is the vegetation of Yosemite National Park and beyond the boundary. The data were produced from 1997 color infrared analog photographs flown by Photo Science through a nationwide contract. ESRI (Environmental Systems Research Institute) was the contrator that coordinated the work. Hundreds of vegetation plots were surveyed within the park and outside the park boundaries by the National Park Service, the U.S. Geological Survey, and The Nature Conservancy. The photointerpretation of the 1997 photos was performed by Aerial Information Systems (Redlands, CA). Photointerpretation was conducted manually using analog photos in stereo pairs and then the polygon boundaries were georeferenced to DOQQS to georectify the map. A plant community classification was developed by NatureServe (in cooperation with the California Department of Fish and Game and California Native Plant Society) by running cluster analysis on the plot data from 604 sites surveyed in 1998 and 1999, 362 sites surveyed in 1989 to 1993, and 774 sites surveyed in 1935 to 1937. A list of mappable types was developed and crosswalked to the floristic classification based on the cluster analysis ('MappingClasstoVegClassTable.xls'). Mapping classification type names are found in 'TYPENAME.dbf;' mapping classification definitions by type are located in Final Comprehensive Mapping Classification Descriptions.doc. The mapping classes were coded and assigned to individual polygons in the vegetation map along with codes for canopy closure, fire severity where applicable, and land use. The floristic classification, key to types and type descriptions are located in the document 'Yosemite Classification Report.doc.' Accuracy assessment field data were collected by NatureServe and analyzed by the NPS and the USGS. Photointerpretation and georectification were completed in 2003; accuracy assessment was completed in 2006. Fields that relate the dataset to the National Vegetation Classification System, the California Wildlifre Habitat Relationship system, and CalVeg system were added to the original dataset by the California Dept. of Fish and Wildlife's Vegetation and Classification Program.

OBJECTID PIFINAL Final code for vegetation class VEG_TYPE The map unit description that corresponds with PIFINAL PIPREFINAL Code for vegetation class prior to accuracy assessment and lumping of classes DENSITY Density, also referred to as vegetative cover, is a quantitative estimate of plant cover derived from viewing the aerial photography in stereo magnification. Photo interpreters assess the total density of vegetation associated with the life form of the alliance being assigned to that polygon. For example, if the polygon is defined as a Jeffrey Pine/Greenleaf Manzanita association, only the tree cover will be evaluated in calculating a density value. If the polygon is defined as a greenleaf manzanita alliance, only the shrub cover will be evaluated, not any emergent tree layer.
