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 HOVE project used a combination of methods to interpret and delineate vegetation polygons. Before going into the field, a trained photointerpreter visually examined the aerial photographs in stereo to identify distinct polygons. Polygons were drawn on photocopies of these photographs. These were carried into the field and during the reconnaissance/sampling phase, polygons were attributed with vegetation or land use map classes and the boundaries modified as needed. After field work was complete, the field photos were digitized using vector editing in ArcGIS. Each vegetation and land use polygon so produced was given density, pattern, and other descriptive attributes. Copies of electronic plot and observation point data and plot photographs were available to the project lead ecologist for reference during final development of the map classes and polygons.
