Urban Imperviousness
NLCD imperviousness products represent urban impervious surfaces as a percentage of developed surface over every 30-meter pixel in the United States. The NLCD 2021 release is update based, so the Impervious Surface products released in 2019 are unchanged and can be used directly with NLCD 2021.This update provides integrated analysis throughout all dates and includes a matching impervious surface descriptor layer. This descriptor layer identifies types of roads, wind tower sites, building locations, and energy production sites to allow a deeper analysis of developed features. No new imperviousness products for Alaska, Hawaii and Puerto Rico are available for NLCD 2021. (Read More)

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.

Maximizing Accuracy of Rangeland Data- RCMAP article April 2024
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. Because of file size limitations, individual years of component cover data are packaged in three time intervals including 1985-1996, 1997-2008, and 2009-2023. Perennial herb and non-sagebrush shrub are derivatives of herbaceous and annual herbaceous cover, and shrub and sagebrush cover, respectively. (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)
