The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. The database is designed to provide cyclical updates of United States land cover and associated changes. Systematically aligned over time, the database provides the ability to move beyond simple change detection to monitoring and trend assessments. The latest evolution of NLCD products continues to focus on consistency, production efficiency, and product accuracy. NLCD products are designed for widespread application in biology, climate, education, land management, hydrology, environmental planning, risk and disease analysis, telecommunications and visualization.

A wide range of urban ecosystem studies, including urban hydrology, urban climate, land use planning and resource management require current and accurate geospatial data of urban impervious surfaces. NLCD imperviousness products represent urban impervious surfaces as a continuous variable and were mapped using a regression tree model. (Read More)

NLCD percent tree canopy is a 30 m raster geospatial dataset covering the conterminous United States, coastal Alaska, Hawaii, and Puerto Rico. These data contain percent tree canopy estimates, as a continuous variable, for each pixel across all land covers and types and are generated by the United States Forest Service. The USFS derives canopy cover from both the spectral information in Landsat imagery, and other available ground and ancillary information. (Read More)
