Description: This vegetation map was created using the U.S. National Vegetation Classification (USNVC), with alliance and association as base map units. Plot data were used to determine classification and assisted in establishing reference 'signatures' for mapping. Color infrared aerial photography from 1999 and sets of true color aerial photography from 2005-2007 (1:3000 scale) were used for mapping. Polygons were manually drawn and then transferred to digital form. Classification resulted in 42 alliances and 46 associations. An accuracy assessment was performed using field verification and overall map accuracy was 89.38%.
