Summary
Description
High resolution vegetation polygons mapped by the National Park Service. To produce the digital map, 1:12,000-scale true color digital ortho-imagery acquired in 2004 and 2006 by the U.S. Department of Agriculture - Farm Service Agencys Aerial Photography Field Office and the National Agriculture Imagery Program (NAIP) were used. In the end, 38 map units (21 vegetated and 17 land use) were developed and directly cross-walked or matched to their corresponding plant associations and land use classes. Draft maps were printed, field tested, reviewed, and revised.
