John Young 2009 2.0 Fgdb raster digital data Vegetation of Shenandoah National Park in Relation to Environmental Gradients Version 2.0 Philadelphia, PA National ParkService http://www1.usgs.gov/vip/shen/shensat1.zip John Young Gary Fleming Wendy Cass Chris Lea 2009 Version 2.0 document National Park Service Technical Report NPS/NER/NRTR-2009/142 Philadelphia, PA National Park Service doi:10.5066/F7W9574C This dataset consists of an AVIRIS hyperspectral image collected 14 May 2000, and transformed using a minimum noise fraction (MNF) technique to compress and separate coherent image signal from noise. The AVIRIS sensor collects data that can be used for characterization of the Earth's surface and atmosphere from geometrically coherent spectroradiometric measurements. This data can be applied to studies in the fields of oceanography, environmental science, snow hydrology, geology, volcanology, soil and land management, atmospheric and aerosol studies, agriculture, and limnology. With proper calibration and correction for atmospheric effects, the measurements can be converted to ground reflectance data which can then be used for quantitative characterization of surface features. The AVIRIS instrument has 224 spectral bands with wavelengths from 400 to 2500 nanometers (visible, near infrared and mid-infrared portions of the spectrum). The AVIRISinstrument is flown on a NASA ER-2 aircraft. This imagery was processed into a mosaic, registered to UTM coordinates, and atmospherically corrected using ACORN software to produce reflectance values. Image bands that fell in atmospheric spectral absorption windows were removed from further processing resulting in 181 useable spectral image bands. AVIRIS images were acquired in two strips that when combined covered all of the park except for small sections of the extreme northern, extreme southern, and extreme western portions of the boundary. In order to enhance spectral processing and to compress the data for use in statistical modeling, we computed a "minimum noise fraction" (MNF) transformation of the 181 spectral bands in ENVI (ITT Visual Information Solutions) image processing software. This technique uses the high data redundancy inherent in hyperspectral imagery and principal components analysis to create new image bands that are separated into coherent signal components and noise components (Greene et al. 1988). After the transform, only the coherent image components are retained for modeling. This resulted in reducing the 181 bands of spectral data from the original imagery to 35 MNF transformed image bands. This imagery was used as part of an effort to map vegetation communities of Shenandoah National Park. 20000514 ground condition Complete None planned Shenandoah National Park and environs -78.836438 -78.148898 38.877081 38.049927 None AIRBORNE VISIBLE AND INFRARED IMAGING SPECTROMETER AVIRIS NASA EARTH RESOURCES-2 NASA ER-2 Minimum Noise Transform MNF National Park System Unit Name Thesaurus Shenandoah National Park National Park System Unit Code Thesaurus SHEN None SNP Virginia None.
