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. The designated base was the USGS digital orthophoto quarter quads (DOQQ’s) series for the Wateree and Gadsden 7.5 minute quadrangles. Creation of the DOQQ’s required having the image plotted onto clear mylar at the mapping input scale, approximately 1:12,000. To facilitate the geo referencing of the polygons, it was determined that the average (nominal) scale of the aerial photography was also approximately 1:12,000. Seven plots were generated at the normal scale on mylar overlays to cover the entire Monument and its environs.
