Frequently Asked Questions
Land cover is foundational information for land managers, scientists, and the general public. Many types of scientific studies have applied annual land cover information including projecting future land use, documenting forest fragmentation or conservation practices, modeling wildfire hazards, tracking water quality and quantity, and understanding change in wildlife habitat and ecosystem disturbance/disease.
Annual NLCD Product Suite
Annual NLCD offers a suite of six annual land use and land cover change in the conterminous United States. Annual NLCD Collection 1.1 is available now.
Data Access
Annual NLCD Science Products are available for download from a variety of data download portals.
Science Product User Guide
Science Product User Guide provides in-depth information on Annual NLCD products and methods and is available for download.
The Annual National Land Cover Database (NLCD) has harnessed the full Landsat data record to provide timely, long-term, and detailed land surface change information. Annual NLCD uses an ensemble of classification and change algorithms to map, monitor, and synthesize the complexities of land use, cover, and condition change through time. The Annual NLCD product suite offers data that describe nationwide land cover and land change over nearly four decades. A new generation of USGS Land Cover mapping, introduced in the Annual NLCD Collection 1 release, leverages advancements in artificial intelligence and machine learning techniques and runs within high-performance computing and cloud processing environments.

Annual NLCD Science Products
The Annual NLCD project has generated a product suite of six geospatial raster land use and land cover science products for the conterminous United States, available annually back to 1985. Annual NLCD products will be updated annually. Check out the Science Product User Guide for in-depth information about Annual NLCD.
Data Access
A suite of six annual integrated land cover and land surface change products are available for the conterminous United States. Products for Alaska and Hawaii are planned. The product suite provides powerful time-series information at a 30-m spatial resolution about annual land cover and its change across time. Products can be accessed via the data access page.
Reference and Validation
Validation of land cover and land cover change information is essential for providing authoritative products to our user community. Validation reports provide estimates of the accuracies and uncertainties of the NLCD land cover products and are derived from well-documented independent reference data. Processing flows, product specifications, uncertainties and known issues are published in validation reports to ensure consistency. See the Reference and Validation products page for more information.
Science Product User Guide
Additional information on Annual NLCD and Annual NLCD science products can be found in the Science User Product Guide. The Science User Product Guide contains in-depth information about Annual NLCD including characteristics of the science products, algorithm description, and accuracy assessment.
