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. We supplied the University of Georgia team with all plot data already collected and a dichotomous key to the communities of the park and we walked throughout the park to help them identify unique mapping units. Since photointerpreters rely heavily on canopy species composition, understory species composition, and disturbance to classify polygons and ecologists rely just as heavily on the shrub and herb layer to classify types, the mapping units and the vegetation classification units do not always “crosswalk” (match up) perfectly. The last step of the project (not detailed in this report) will be to work reconcile mapping units with vegetation associations to produce mapping units that match up well with the ecological units of the National Vegetation Classification.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Aerial photography from 2001 served as the base map, and field sampling was conducted from 2002–2006. Spatial data were digitized onscreen over digital orthophoto mosaics created from scanned color infrared, stereo pair 1:6,000 scale aerial photography using a 0.5 hectare minimum mapping unit.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. In the course of developing a land cover map for VICK, the NWRC acquired leaf-on 3-band color infrared (CIR) photographic images of VICK from an aircraft platform on September 30, 2004 in nine photographic frames, at a scale of 1:24,000. NWRC created [presumably scanned the frames] a 1-meter resolution digital orthophoto mosaic image (.tif) of VICK and environs up to 100 meters from the park boundary. We used this imagery indirectly in employing the land cover map boundaries for thematically coarse land cover classes and directly for more accurately mapping forested vegetation associations for the NPSVI map for VICK.

Photo Date: 10/24/2000, Scale: 1:12,000 Area(ac): 3955 The CIR aerial photographs in transparency format were scanned at 600 dpi (42 μm) using an Epson Expression 10000XL flatbed scanner. This scanner is capable of scanning materials up to 11x17‖ in size at optical resolutions up to 1200 dpi and is equipped with a backlight attachment for scanning transparent materials. The 600 dpi scanning resolution was selected to balance the resolution requirements for the orthophotos with data storage and processing considerations. The photographs were laid on the scanning surface and, to reduce distortions, a heavy piece of clear glass was placed on top to ensure flatness of the film during scanning. Each photo was then scanned using Adobe Photoshop and saved as a 24-bit color TIFF file. During scanning, care was taken to scan the full frame of the photograph, including the corner fiducial marks and marginal data. File names for the scanned photographs were assigned according to the flight line and frame number. For example, photo 13 from flight line 2 was named 2-13.tif. Photos from each park were stored in separate folders on the CRMS Data server. All photos from each flight line were scanned. For original photos of 1:12,000 and 1:16,000 scales, the resulting pixel sizes were approximately 0.5 m and 0.67 m, respectively. After the photos were scanned, the original film transparencies were turned over to the photointerpreters while the photogrammetric operations continued using the digital data.
