EnviroAtlas - 2011 Land Cover, Impervious Surface, and Riparian Land Cover Proportions by County for the Conterminous United States

This EnviroAtlas dataset represents land cover across a county and in riparian areas for each county in the conterminous United States for use in the Compare my Area tool. These metrics include the percentage of land area that is classified as natural, forest, wetland, agricultural, natural, and developed land cover using the EnviroAtlas hybrid Cropland Data Layer (CDL) - 2011 National Land Cover Dataset (NLCD); the percentage of impervious surface based on the 2011 NLCD Percent Developed Impervious dataset; and the percentage of land area within 45 meters of streams, rivers, and other hydrologically connected waterbodies within each county that is classified as forest (excluding wetlands), forest including woody wetlands, and natural land cover, based on the 2011 CDL-NLCD. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
