Geospatial data for the Vegetation Mapping Inventory Project of Richmond National Battlefield Park

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.

Spatial data from field observation points and quantitative plots were used to edit the formation-level maps of Richmond National Battlefield Park to better reflect vegetation classes. Using ArcView 3.3, polygon boundaries were revised onscreen over leaf-off photography. Units used to label polygons on the map (i.e. map classes) are equivalent to one or more vegetation classes from the regional vegetation classification, or to a land-use class from the Anderson Level II classification system. Each polygon on the Richmond National Battlefield Park map was assigned to one of twenty-one map classes based on plot data, field observations, aerial photography signatures, and topographic maps. The mapping boundary was based on park boundary data obtained from Richmond National Battlefield Park in June 2004.
