Land Cover
The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. NLCD 2021 represents the latest evolution of NLCD land cover products focused on providing innovative land cover and land cover change data for the Nation. NLCD 2021 offers 9 integrated epochs of land cover for years 2001, 2004, 2006, 2008, 2011, 2013, 2016, 2019, and 2021. chs (2001 – 2021) and are directly comparable across the full time series and suitable for multi-temporal analysis. The NLCD 2021 release is update based, so the Land Cover and Impervious Surface products released in 2019 are unchanged and can be used directly with NLCD 2021. Science products and the change index will need to be reacquired to contain the additional 2021 change. Specific map products include:Developed classes in these years are directly derived from percent developed impervious surface and include a descriptor label that identifies the type of each impervious surface pixel. The NLCD Land Cover change index combines information from all years of land cover change and provides a simple and comprehensive way to visualize change from all 9 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 2021 does not yet contain updated products for Alaska, Hawaii and Puerto Rico.

Tree Canopy
NLCD tree canopy cover geospatial datasets with spatial resolutions of 30 m are produced by the USDA Forest Service. Tree canopy cover is derived from multi-spectral satellite imagery and other available ground and ancillary information. Tree canopy products for the period 2011-2021 are available for the conterminous United States, and by summer 2023, they will also cover coastal south east Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands.

RCMAP – Basemap (2016)
RCMAP base component products characterize the percentage of each 30-meter pixel in the Western United States covered by shrub, herbaceous, bare ground, litter, sagebrush, big sagebrush and annual herbaceous, along with estimating shrub height and sagebrush height. These products have been produced by USGS in collaboration with the Bureau of Land Management. Component products are designed to be used individually or combined to support a broad variety of applications.
Please note these new Revised (071520) rangeland products will differ from the first generation of circa 2016 fractional cover maps, a more aggressive masking of tree canopy cover was applied to each rangeland component. Specifically, we have lowered the tree canopy cover threshold for exclusion from 40 to 25%. For pixels with 1-25% tree canopy cover we ensured that our primary components (shrub, herbaceous, litter, and bare ground) cover summed to 100% when added with the tree canopy. And, for the secondary components (sagebrush, big sagebrush, sagebrush height and shrub height) we reconciled to the primary component (shrub), excluding any pinyon-juniper woodlands. (Read More)

RCMAP - Time-Series - Trends
The RCMAP product suite includes 10 components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub height. Data characterize the percentage of each 30-meter pixel in the Western United States covered by each component for each year from 1985-2023 - providing change information for 39 years. (Read More)

Ecological Potential
Rangeland Ecological Potential - Component Cover, Cover Departure, and Vegetation States.
Ecological Potential rangeland fractional cover data products represent the potential cover given the most productive, least disturbed, portion of the 1985-2020 Landsat archive. Models used to predict Ecological Potential cover were trained on ecologically intact sites where annual herbaceous cover is low, no known disturbance or land treatment has occurred over the study period, and bare ground cover is relatively lower than expectations (Read More)
