Annual NLCD Impervious Descriptor
The Annual National Land Cover Database (NLCD) Impervious Descriptor product represents categorical data for developed land cover distinguishing roads from urban non-road.
The Impervious Descriptor product provides additional categorical information for urban and rural areas. The Impervious Descriptor product classifies impervious areas of the NLCD Land Cover product into road and urban (i.e., other built surfaces) classes. Unlike versions of NLCD prior to the Annual NLCD Collection 1.0, this is not a reporting layer for urban source information but is the direct result of a supervised classification algorithm.
