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. 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. Two digital orthophoto mosaics were produced for Gettysburg National Military Park (GETT) and Eisenhower National Historic Site (EISE) because aerial photography was acquired in two separate flights and because the file size of a single mosaic would be unmanageably large. One mosaic covers the western portion of Gettysburg National Military Park and all of EisenhowerNational Historic Site and is referred to below as the GETT/EISE mosaic. The second mosaic covers the eastern, East Cavalry Field (ECF) portion of Gettysburg National Military Park and is referred to below as the GETT/ECF mosaic. Color infrared, stereo pair 1:6,000 scale aerial photography for both mosaics was acquired from two overflights on April 13, 2003, during leaf-off conditions, by Kucera International.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. A vegetation map of Fredericksburg and Spotsylvania National Military Park was created following the USGS-NPS Vegetation Mapping Program protocols. Vegetation map classes were crosswalked to the Natural Communities of Virginia and to the USNVC in order to provide a regional and global context for the park’s vegetation. Ten map classes represent later successional forests and cover approximately 48% (1,510 ha [3,731 ac]) of the park. These map classes can be broadly characterized based on different environmental settings, such as upland forests, alluvial floodplain forests, and non-alluvial wetlands. Early successional or transitional vegetation covers 31% (966 ha [2,387 ac]) of the land in the park. Cultural map classes cover 21% (680 ha [1,680 ac]) of the park, and include the Anderson land-use categories and other man-made or maintained areas in the park.

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.
