Urban Hyperspectral
Pervious and impervious surfaces in urban environments can have
very similar, or indistinguishable, spectral properties. Spectral mixing
at moderate spatial resolutions further reduces accuracy ofreflectance-
based attempts to map impervious surfaces. However, mapping fractional
pervious surface can produce verifiable results without unnecessary, and
incorrect,assumptions about permeability and reflectance. Details in:
Dimensional analysis of urban AVIRIS imagery quantifies
variation of spectral dimensionality with spatial and spectral
resolution. Details in:
