Published by National Park Service | Department of the Interior | Catalog Last Checked: March 04, 2026 at 06:53 AM | Dataset Last Updated: January 01, 1996 at 12:00 AM
This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here. The vegetation map was created from 1996 1:12,000 scale color infrared aerial photographs (0.5 hectare minimum mapping unit). All vegetation and land-use information was then transferred to a GIS database using the latest grayscale USGS digital orthophoto quarter-quads (DOQQs) as the base map and a combination of on-screen digitizing and scanning techniques.
