USGS EROS Archive – Land Cover – Annual NLCD Collection 1 Impervious Descriptor
The Annual National Land Cover Database (NLCD) Impervious Descriptor product provides a map of road networks within impervious areas and distinguishes roads from other built surface classes.
Annual NLCD Spectral Change Day of Year in the h04v01tile in the Northwest United States.
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 legacy versions of NLCD prior to the Annual NLCD Collection 12023 edition, this is not a reporting layer for urban source information but is the direct result of a supervised classification algorithm.
Annual NLCD Collection 1 Product Suite products are processed to 30-meter resolution on an Albers Equal Area Conic (AEA) projection using the World Geodetic System 1984 (WGS84) datum. Annual NLCD products are created as raster images stored as GeoTIFFs with accompanying metadata. The products delivered via EarthExplorer (EE) are Tiled products processed to a common tiling scheme of uniform dimensions bounded by static corner points in a defined grid system. Each tile contains 5,000 x 5,000 30-meter pixels.
