Summary
Abstract: Characterization of terrestrial vegetation from the Advanced Very High
Resolution Radiometer (AVHRR) on the global to regional scale has traditionally
been accomplished using classification schemes with discrete numbers of
vegetation classes. Representation of vegetation into a limited number of
homogeneous classes does not account for the variability within land cover, nor
does the portrayal recognize transition zones between adjacent cover types. An
alternative paradigm to describing land cover as discrete classes is to
represent land cover as continuous fields of vegetation characteristics using a
linear mixture model approach. This 1992 product corresponds with the MODIS VCF
Percent Tree Cover Product.
