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.
