Paper Abstract

NASA airborne visible/infrared imaging spectrometer (AVIRIS) data were acquired in the summer of 1991 over a Norway spruce forested area in southeastern Austria for the purpose of assessing the potential of hyperspectral data to measure changes in canopy biochemical constituents related to tree damage. In support of the aircraft data acquisition, 312 needle samples were collected from 52 damaged tree stands representing low, moderate, and high levels of crown needle loss and analyzed for nitrogen, lignin, and cellulose. Multivariant statistical analysis of the AVIRIS and foliage biochemical data sets produced a set of wavelengths for estimating canopy nitrogen, lignin, and cellulose concentrations in Norway spruce stands that can be used to provide a measure of forest damage.
