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. Imagery Date: 10/25/2001, Scale 1:12,000, Area: 654 ac Overstory vegetation was interpreted from the 1:12,000 to 1:16,000 scale leaf-on color infrared aerial photographs in 9 x 9 inch film transparency format.

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 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.

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. Imagery is from 1:12,000 scale digital color-infrared aerial photography (flown 31 May 2009) through heads-up-digitizing in ArcGIS (Version 9.3, © 2008 Environmental Systems Research Institute, Redlands, California). Airborne GPS data were provided by Aero-Metric, Inc, as were ground check point data. The project was referenced to the North American Datum of 1983/2007 (NAD83/07), Universal Transverse Mercator Zone 17 horizontally and to the North American Vertical Datum of 1988 vertically. The aerial photographs were taken on 31 May 2009 at a scale of 1:12,000. The calibration focal length for the photos was 152.823 mm. Contact prints of the CIR imagery were created for use in the field, and diapositives of the CIR set were created for photo-interpretation.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Since WABA represented a fairly small and accessible site no new imagery or aerial photography was deemed necessary for this project. Instead existing sources of imagery were evaluated and two NAIP products were selected to be used as base maps. Images included the 2003 and 2005 NAIP products. The 2003 had 1-meter resolution and the 2005 had 2-meter resolution. Both were acquired at 1:12,000-scale, which is adequate for vegetation mapping purposes. The 2003 imagery was acquired in true color and at higher resolution that helps highlight subtle differences in vegetation.
