Background spectral library for Fort A.P. Hill, Virginia

We describe development of a background spectral library for Fort A. P. Hill, located in northeastern Virginia, based on hyperspectral images and an extensive land cover database. The database was used to identify areas of uniform land cover. The library contains means and standard deviations for 15 spectra measured in these uniform areas. Terrain categorization products consist of classification maps and fractional abundance maps determined by linear mixture analysis. There is excellent qualitative agreement between the linear unmixing results and the known land covers.
