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. A set of 1:12,000-scale CIR aerial photographs was collected on October 9, 2005 (funded by the NPS VIP, and the photo mission was supervised by GLKN staff). This set of photography covered the full project boundary extent and was the primary imagery used in photointerpretative mapping. In addition to the CIR photos, a set of 1:12,000-scale TC aerial photographs were collected May 11, 2004, providing deciduous leaf-off viewing of the entire extent. This photo mission was funded and supervised by GLKN staff. Having the TC photos gave interpreters a definite advantage in determining evergreen tree and shrub components within forest communities that are otherwise obscured by deciduous tree canopy on the fall-season CIR photos, thus giving credence to Avery’s statement regarding lack of a single all-purpose film emulsion.
