This data represents a vegetation map for New River Gorge National River. It contains nonoverlapping polygons which represent vegetation classes, aquatic features, and cultural features. Vegetation types were classified based on statistical analysis of plot data collected on the ground from 1998 through 2005. Polygons were delineated based on interpretation of digital and hard copy aerial photography flown in 2003.
This data represents a vegetation map for Bluestone National Scenic River. It contains nonoverlapping polygons which represent vegetation classes, aquatic features, and cultural features. Vegetation types were classified based on statistical analysis of plot data collected on the ground from 2003 through 2005. Polygons were delineated based on interpretation of digital and hard copy aerial photography flown in 2003.
This data represents a vegetation map for Gauley River National Recreation Area. It contains nonoverlapping polygons which represent vegetation classes, aquatic features, and cultural features. Vegetation types were classified based on statistical analysis of plot data collected on the ground from 1995 through 2009. Polygons were delineated based on interpretation of digital and hard copy aerial photography flown in 2003. This data set was created by clipping the GARIvegetation feature class by the boundary of Gauley River National Recreation Area. Multipart polygons created by the clip operation were converted to single part polygons. Hectares and acres were calculated for each polygon using XTools.
These data represent a vegetation map for Vicksburg National Military Park and Vicksburg National Cemetery. The data consist of nonoverlapping polygons which represent National Vegetation Classification vegetation types, and non-vegetated land cover features. Vegetation types were classified based on analysis of plot data and supplemental observations collected on the ground from 2004 through 2010. Polygons were delineated based on interpretation of digital aerial photography flown in 2004 and terrian modeling. More detailed methodology is documented in Lea, Waltermire, and Nordman (2013).
