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.

Based on the plot sampling data and the classification of 43 vegetation associations, the vegetation cover type map was revised to correct errors and create more accurate vegetation polygon boundaries at the USNVC association level. In this iteration, plot data, field observations, classification analyses, aerial photography signatures, and topographic maps were used to revise polygon boundaries and attributes.

Thematic accuracy of this preliminary vegetation association map was then assessed. Based on accuracy assessment sampling data, the association map was revised again to correct errors and create the final vegetation association polygon boundaries. In this final revision, accuracy assessment data were used in addition to the resources noted above to revise polygon boundaries and attributes.
