Agricultural land cover is defined using the EnviroAtlas hybrid Cropland Data Layer (CDL) - 2011 National Land Cover Dataset (NLCD). Percentage slope values were derived from the 1 arc-second National Elevation Dataset (NED). 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). This dataset is useful for evaluating the potential value of ecosystem services provided by vegetation communities, and the impacts of developed land cover. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. completed EnviroAtlas Coordinator U.S. Environmental Protection Agency, Office of Research and Development-Sustainable and Healthy Communities Research Program, EnviroAtlas Geospatial Data Owner (919) 541-3832 109 T.W.

The land cover input is the EnviroAtlas 2011 CDL-NLCD, a raster dataset that is a hybrid of the 2011 NLCD (www.mrlc.gov/) and the 2011 CDL (https://www.nass.usda.gov/Research_and_Science/Cropland/SARS1a.php). The slope grid input was derived from the 1 arc-second NED (https://nationalmap.gov/elevation.html). For more information on the metric calculation, please see the ATtILA User's Manual included with the toolbox. A comprehensive list of metric creation steps is included in the Processing Steps.
