    • LCMAP CONUS Reference Data Product 1984-2021 land cover, land use and change process attributes

    Metadata Updated: January 21, 2026

    This product contains LCMAP CONUS Reference plot location data in a .shp format as well as annual land cover, land use, and change process variables for each reference data plot in a separate .csv table. The same information available in the.csv file is also provided in a .xlsx format. The LCMAP Reference Data Product was utilized for evaluation and validation of the Land Change Monitoring, Assessment, and Projection (LCMAP) land cover and land cover change products. This LCMAP Reference Data Product includes the collection of an independent dataset of 25,000 randomly-distributed and 2,000 stratified random 30-meter by 30-meter samples across the conterminous United States (CONUS). The 2,000 samples were selected using a stratified random sampling process with 4 strata based off the LCMAP Collection 1.0 Science Products. The LCMAP Reference Data Products collected variables related to primary and secondary land use, primary and secondary land cover(s), change processes, and other ancillary variables annually across CONUS from 1984–2021.
