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.

All classification plot information sampled in 2009 was documented, summarized, and geo-processed into a GIS shapefile that could be overlain on the NAIP ortho-imagery. CTI created preliminary map classes (also known as map units) based largely on whether the vegetation surrounding the plot locations could be readily identified and delineated on the NAIP imagery (i.e. photo signature development). Once the photo signatures were inventoried they were matched or cross-walked back to the preliminary list of plant associations prepared in the project work plan. Supplemental land-use and land-cover classes (Anderson 1976, amended 2002) were added to classify non-vegetated areas such as developments, roads, streams, ponds, bare ground, and active agricultural areas. All obvious land-use features were manually digitized and incorporated with the project boundary into a draft GIS layer. Initial interpretation and mapping focused only on delineating obvious landforms (e.g., geologic exposures and land use) and physiognomic features (e.g., grasslands versus shrublands versus woodlands).
