The goal of this project is to provide the Nation with complete, current, and consistent public domain information on its land use and land cover. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (for example, urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. NLCD's impervious surface descriptor product identifies types of roads, core urban areas, and energy production sites for each impervious pixel to allow deeper analysis of developed features. NLCD 2019 represents the latest evolution of NLCD land cover products focused on providing innovative land cover and land cover change data for the Nation. This type can occur with significant other grasses or other grass like plants, and includes sedge tundra and sedge tussock tundra.
