Notice to users: The Annual NLCD product release is planned for late October 2024. At that time further content, such as product documentation and full access to data products, will become available and referenced from this site.
Annual National Land Cover Database (NLCD) Collection 1.0 includes a suite of six raster land use and land cover science products for the conterminous United States. It covers the period between 1985 and 2023. The Science Product User Guide contains in-depth background and documentation about the Annual NLCD product suite

Annual NLCD Science Products
Land Cover (LndCov): Depicts the predominant thematic land cover class within the mapping year with respect to broad categories of artificial or natural surface cover.
Land Cover Change (LndChg): Depicts land cover change between one product year and the next. Changes are represented in the latter year.
Land Cover Confidence (LndCnf): Depicts the probability value for the land cover class derived from the classification method.
Fractional Impervious Surface (FctImp): Depicts the fractional surface area of the map unit (pixel) that is covered with artificial substrate or structures.
Impervious Descriptor (ImpDsc): Depicts categorical data for developed land cover distinguishing roads from urban-non-road.
Spectral Change Day of Year (SpcChg): Depicts the day-of-year (DOY) on which a significant deviation in Landsat surface reflectance was detected within the calendar year.
Table below shows the Annual NLCD Collection number, the related Landsat ARD source, the product date range, and the release date of the collection.
