The Forest Service-Field Services & Innovation Center-Geospatial Office builds and maintains Tree Canopy Cover (TCC) datasets for the conterminous U.S. (CONUS), coastal Alaska (SEAK), Puerto Rico, and the U.S. Virgin Islands (PRUSVI). Since the TCC datasets cover all lands including federal, state, and private lands, multiple divisions of the Forest Service contribute funding supporting the development and production of the datasets. These divisions include the National Forest Systems, State and Private Forestry, and Research and Development. The TCC datasets are Landsat and Sentinel-2 based with a spatial resolution of 30 meters.
An annual Science product (direct model outputs, per pixel SE, and model uncertainty) with maps and data for years 1985-2023, that serve multiple user communities.
Additional 2023.5 TCC product suite components and download links are provided below under "Current Data Release".
Additional documentation describing the components of the TCC Product Suite (workflows, inputs, models, QC and review processes, etc.) is available at the bottom of this page.
Science TCC product includes 30-meter spatial resolution maps of TCC and standard error for years 1985-2023.
Two-layer dataset, with modeled TCC values on every pixel, along with a standard error value + metadata
Provides objective numerical model outputs
Masks and thresholds are not applied to the Science version. TCC in water bodies or non-tree croplands (e.g., center-pivot irrigated fields) may be present.
Produced by the Forest Service
Data for the years 2008 through 2023 are available below.
Description:
NLCD TCC product suite includes 30- meter spatial resolution maps of TCC for the years 1985 through 2023.
The NLCD TCC data are the result of more in-depth post-processing of the Science products, including various masking (i.e., water and non-tree agriculture), filtering, minimum-mapping unit (MMU) routines, and a process to reduce interannual noise and return longer duration trends.
Produced by the Forest Service as a partner in the Multi-Resolution Land Characteristics Consortium (MRLC)
Primary User Community:
This version serves a user community that prizes statistics over visual appearance.
This community typically has access to advanced geospatial and statistical analysis resources.
Primary User Community:
This version serves a large part of the NLCD user community that desires:
Maps with reasonable cartographic appearance and reduced interannual noise.

This version serves a large part of the NLCD user community that desires:
Maps with reasonable cartographic appearance and reduced interannual noise.
Two-layer dataset, with modeled TCC values on every pixel, along with a standard error value + metadata
Closest to objective numerical model outputs
Masks are not applied to the Analytical version to clean up the visual appearance of the data. In the Analytical version, raw modeled tree cover in water bodies or non-tree croplands (e.g., center-pivot irrigated fields) may be present.
Data for the years of 2011 and 2016 are available
Description:
Single-layer dataset, with TCC values only (no standard error layer included) + metadata
TCC layer from the upstream “FS-Analytical” version of the product + application of masks to refine dataset visual appearance
Masks are applied to remove modeled TCC in water bodies, non-tree croplands, and in areas where the standard error is much higher than the TCC value itself. Essentially, pixels for which confidence in the pixel being tree-covered is very low are filtered out.
Data for the years of 2011 and 2016 are available
Description:
Three-layer dataset that is an integrated data stack (i.e., 2011 TCC + change = 2016 TCC for all pixels)
Data for the years of 2011 and 2016 are available, as well as estimated TCC change between the nominal years of 2011 and 2016
Produced by FS/GTAC as a partner in the Multi-Resolution Land Characteristics Consortium (MRLC)
Primary User Community:
This version serves a user community that prizes statistics over visual appearance.
This community typically has access to advanced geospatial and statistical analysis resources.
Primary User Community:
This version serves a user community desiring better visual appearance of 2011 and 2016 timesteps for cartographic purposes.
Primary User Community:
This version serves a large part of the NLCD user community that desires:
an integrated data stack with 2011 TCC + change = 2016 TCC
an estimate of change beyond simple subtraction on all pixels, everywhere across all AOIs
maps with reasonable cartographic appearance, yet this user community is willing to trade minor visual artifacts for the integrated data stack, where values “line up” (i.e., 2011 TCC + change = 2016 TCC)

Data for the year 2011 are available
Description:
Released in 2014 as part of the 2011 NLCD
Single-layer dataset, with TCC values only (no standard error layer included) + metadata
TCC layer from the upstream “FS-Analytical” version of the product + application of masks to refine dataset visual appearance
Masks are applied to remove modeled TCC in water bodies, non-tree croplands, and in areas where the standard error is much higher than the TCC value itself. Essentially, pixels for which confidence in the pixel being tree-covered is very low, are filtered out.
Data for the year 2011 are available
