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. Hyperspectral images from NASA’s AVIRIS platform were acquired for this research. Two high altitude AVIRIS images were collected from NASA ER-2 aircraft, one on 14 May 2000 and another on 13 July 2001. High altitude AVIRIS pixels have approximately 17 m spatial resolution and 224 bands at 10 nm intervals between 400-2500 nm. In addition to hyperspectral imagery, a time-series of Landsat TM images from five dates was also used to test the ability of multi-temporal Landsat data to map forest associations. The results of this analysis would be used to fill in small portions of Shenandoah National Park that were not covered by AVIRIS image data. The time-series included three early spring images: 12 April 1984, 26 May 2000, and 24 May 2002, and two early fall images: 19 September 1984 and 5 September 2002.

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. The imagery we used was acquired by Digital- Globe Inc.’s Quickbird satellite on August 27, 2006, as a new, tasked acquisition for this project. Image preprocessing and initial interpretation to the formation level were done at the Arizona Remote Sensing Center, University of Arizona. The imagery product purchased was the “Ortho-ready Standard” bundle of four spectral bands (blue, green, red and near-infrared) at 2.4-m spatial resolution, plus the broadband panchromatic data at 0.6-m resolution. This imagery is intended to be orthorectified by the user and is only coarsely geo-registered, with a nominal spatial accuracy of 23 m CE90—meaning that 90% of features in the imagery must be within 23 meters of their true location on the ground.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Horizons, Inc. (Rapid City, SD) flew true-color aerial photography for GRTE at scales of 1:12,000 and 1:40,000 on July 10-11, 2002. The 1:12,000 scale photos were acquired in stereo with 60 percent forward overlap and 40 percent side overlap. In addition to 9x9 inch prints of the 1:12,000-scale aerial photography, we also had Horizons Inc develop new orthophotography from the 1:40,000 scale aerial photos at a uniform scale of 1:12,000 with 1-meter pixel resolution.

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. Project photography was color-infrared (CIR) stereo-paired diapositives, average scale 1:6,720, flown during September 1995. The project scale was established at 1:6720. The reason for this was the CIR imagery and the orthophotos were not concurrent with one another: the CIR imagery was taken in 1995; the orthophoto was created from imagery taken in 1992.
