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:
