EROS is central to the creation of the National Land Cover Database (NLCD), which is updated every five years and stands as the definitive land cover database for the United States.
NLCD is generated in cooperation with the Multi-Resolution Land Characteristics Consortium (MRLC) a partnership of Federal agencies working together to produce current, nationally consistent, land cover products for all 50 states and Puerto Rico.

NLCD is used for thousands of applications that require information on landcover location or where it is changing.
The latest iteration is NCLD 2019. It contains 28 different land cover products characterizing land cover and land cover change across 8 epochs from 2001-2019, urban imperviousness and urban imperviousness change across 8 epochs, tree canopy and tree canopy change across 2 epochs from 2011-2016 and western U.S. shrub and grassland areas for 2016. Data are available on the MRLC website, either as prepackaged products or custom product areas can be interactively chosen using the MRLC viewer.
NLCD 2019 offers land cover for years 2001, 2003, 2006, 2008, 2011, 2013, 2016, 2019, as well as impervious surface and impervious descriptor layers for each epoch. These products update all previously released versions of landcover and impervious products for CONUS (NLCD 2001, NLCD 2006, NLCD 2011, NLCD 2016) and are not directly comparable to previous products. NLCD 2019 land cover and impervious surface product versions of previous dates must be downloaded for proper comparison.
NLCD also includes an NLCD Land Cover Change Index. This index provides a simple and comprehensive way to visualize change from all 8 dates of land cover in a single layer. The change index was designed to assist NLCD users to understand complex land cover change with a single product.
NLCD's impervious surface descriptor product identifies types of roads, core urban areas, and energy production sites for each impervious pixel to allow deeper analysis of developed features. NLCD 2019 also includes a wind energy layer across all impervious products.
