Annual NLCD Reference Data and Validation Metrics Now Available on MRLC

Published Sep 24, 2025

The U.S. Geological Survey has added a new outlet for Reference and Validation (R&V) data for Annual National Land Cover Database (NLCD) Conterminous U.S. (CU), Collection 1.0. In addition to availability on the USGS ScienceBase-Catalog, the R&V data are now hosted right here on MRLC.gov.
These R&V data provide Annual NLCD users with a statistical accuracy assessment of the land cover products, as well as the source reference data. This information helps users understand the accuracy of Annual NLCD and supports better decisions in research, land use planning, and resource management.

RCMAP Ecological Potential Data Now Available

Published Jul 28, 2025

A new generation of RCMAP Ecological Potential (EP) vegetation cover components are now available. Rangelands have immense inherent spatial and temporal variability, yet assessments of land condition and trends are often assessed relative to the condition of a limited number of representative points or in some cases reference data for comparison is lacking. Understanding of the potential vegetation conditions of a site in an undisturbed state is invaluable for interpreting trends, disturbance impact, and restoration targets. EP was defined as the potential fractional cover of components (bare ground, herbaceous, litter, shrub, sagebrush, and tree) in the least disturbed and most productive spaces and times of western North America since 1985. This dataset enables: 1) setting realistic expectations for restoration and management targets, 2) better understanding of the extent of vegetation departure from potential and 3) improved spatial understanding of vegetation composition and productivity variation.
