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. Aerial photography was the foundation imagery for the vegetation map. The primary photo-base for this project was a National Agricultural Imagery Program (NAIP) digital ortho-photo quarter quad (DOQQ). This photo was acquired on September 12, 2004 as a digital, three-band, color-infrared dataset (with the visible green, visible red, and near-infrared wavelength portions of the spectrum partitioned into Bands 3, 2, and 1 respectively). As a part of their original processing, the photos had been orthorectified into a one-meter spatial resolution and projected into a UTM Projection, NAD83 Datum, GRS80 spheroid as a Mr. SIDs data format. For this project, the photo was imported into an ERDAS Imagine (v. 9.3) .img format. In addition, BingMaps photo database, high-resolution, natural-color imagery from 2010 was used to support final image interpretation.
