Tree Canopy Cover

Monitor annual tree canopy cover (TCC) that is the percent of ground covered by tree material (leaves, needles, branches).

EXPLORE DATA

Several web mapping applications are available to explore, summarize, and produce reports of how our landscape is changing.


LCMS Data Explorer

The LCMS Data Explorer is designed to make LCMS and TCC data accessible and actionable for a wide range of users, from land managers and scientists to the general public. Users can:

  • Zoom and pan across the United States to view landscape change at national, regional, or local scales.
  • Select specific years to visualize annual changes in vegetation cover, land cover, land use, and tree canopy cover.
  • Overlay multiple LCMS and TCC data products to compare trends and patterns over time.
  • Generate summary statistics and charts for areas of interest.
  • Download data for further analysis or reporting.

LCMS Dashboard

The LCMS Dashboard is designed to provide the ability to quickly summarize and generate reports of how our landscapes are changing. Users can:

  • Select a summary area by selecting State/County or choose the Forest Service hierarchy to browse through Forest Service Regions, Forests, and Ranger Districts
  • Define the analysis years using the year slider.
  • Browse the LCMS products available in the Tabs. The three LCMS products are Vegetation Change, Land Cover , and Land Use. The selected LCMS product will be visible on the map with a change slider to compare the first and last year selected.
  • TCC products are included
  • Export a pdf report

Additional LCMS Explorers

The LCMS Base Learner Explorer allows users to view raw input data, compare temporal segmentation results, visualize synthetic composite time-lapses, and download base learner and segmentation data. It is intended for researchers and analysts interested in the underlying data used to create LCMS model outputs.

LCMS In-Motion provides interactive time-lapse animations for exploring yearly changes in LCMS land cover, land use, and change classes, with options to export animations for presentations or reports.



ABOUT THE DATASETS


About LCMS

Knowing where, when, and what factors create change across landscapes is critical to making sound land management decisions. To support land managers and scientists with this need, an interagency effort between leading remote sensing scientists and application specialists in the U.S. Department of Agriculture Forest Service, U.S. Geological Survey, NASA, and numerous universities have collaborated to develop and produce a Landscape Change Monitoring System (LCMS).


LCMS is a remote sensing-based system for mapping and monitoring landscape change across the United States. LCMS provides a “best available” map of landscape change that leverages advances in time series-based change detection techniques, Landsat and Sentinel data availability, cloud-based computing power, and big data analysis methods.


The LCMS Science Team initially developed LCMS methods (Cohen et al., 2018; Healey et al., 2018). The LCMS Production Team and Science Team review methods frequently to ensure the LCMS mapping process is based on the best available science. All LCMS map products are recreated annually from 1985 to the most recent full growing season. LCMS mapping areas include all the United States and its territories. The current operational set of outputs covers the conterminous United States (CONUS), Alaska (AK), Puerto Rico and U.S. Virgin Islands (PRUSVI), and Hawaii (HI).

About TCC

The Tree Canopy Cover (TCC) data products are developed and maintained by the USDA Forest Service through integrated teams and support from the Geospatial Office and Research and Development - Forest Inventory and Analysis. Because the TCC datasets cover all USA 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. TCC data support a variety of work including timber management, urban forestry, and forest monitoring.


TCC mapping areas include all the United States and its territories. The current operational set of outputs covers the conterminous United States (CONUS), Southeastern Alaska (SEAK), Puerto Rico and U.S. Virgin Islands (PRUSVI), and Hawaii (HI).
