• Geospatial data for the Vegetation Mapping Inventory Project of Yosemite National Park [and Devils Postpile National Monument]

    Metadata Updated: March 17, 2021

    The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles.

    High resolution vegetation polygons mapped by the National Park Service. 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. Photointerpretation and georectification were completed in 2003; accuracy assessment was completed in 2006.
