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 mapping component of the DINO project used a combination of methods to interpret and delineate vegetation polygons. A trained photointerpreter drew polygons on Mylar overlays covering 1m resolution, 1:12,000-scale, digital orthophoto quarter quadrangles (DOQQs). In order to see fine detail, the interpreter examined the 9 x 9-inch 1:12,000-scale aerial photographs in stereo, and transferred this information to the DOQQ. The Mylar overlays were scanned and corrected digitally for distortion. Digitizing was performed using vector editing in ArcGIS. The monument and environs were interpreted and mapped to the same level of detail.

Each polygon was assigned a map class number, alpha code and name, Anderson land use class, and vegetation density, pattern, and height attributes. In order to improve the utility of the map and related data, the spatial database was moved into a geodatabase format.
