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. 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.

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 from 2002 served as the base map, and field sampling was conducted from 2002–2005. 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-ha minimum mapping unit.

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. Two sets of digital orthophoto mosaics, leaf-on (fall) and leaf-off (spring), were created for Petersburg National Battlefield. To achieve manageable file sizes, each set is made up of five files that, together, cover the entire geographic extent of the park. Kucera International acquired color infrared, stereo pair 1:6,000 scale aerial photography for the leaf-on mosaics on October 23, 2001, and for the leaf-off mosaics on February 28, 2002. The photography was delivered to the NPS, quality checked, accepted as provided, and sent to NCSU-CEO.

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.
