CropScape - Cropland Data Layer
<p>The Cropland Data Layer (CDL), hosted on CropScape, provides a raster, geo-referenced, crop-specific land cover map for the continental United States. The CDL also includes a crop mask layer and planting frequency layers, as well as boundary, water and road layers. The Boundary Layer options provided are County, Agricultural Statistics Districts (ASD), State, and Region. The data is created annually using moderate resolution satellite imagery and extensive agricultural ground truth. </p> <p>Users can select a geographic area of interest or import one, then access acreage statistics for a specific year or view the change from one year to another. The data can be exported or added to the CDL. The information is useful for issues related to agricultural sustainability, biodiversity, and land cover monitoring, especially due to extreme weather events. </p><div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: CropScape and Cropland Data Layer - National Download.</p> <p>File Name: Web Page, url: <a href="https://www.nass.usda.gov/Research_and_Science/Cropland/Release/index.php">https://www.nass.usda.gov/Research_and_Science/Cropland/Release/index.php</a> </p><p>Downloads available as zipped files at <a href="https://www.nass.usda.gov/Research_and_Science/Cropland/Release/index.php">https://www.nass.usda.gov/Research_and_Science/Cropland/Release/index.php</a> --</p> <ul> <li>National CDL's -- by year, 2008-2020. Cropland Data Layer provides a raster, geo-referenced, crop-specific land cover map for the continental United States. The CDL also includes a crop mask layer and planting frequency layers, as well as boundary, water and road layers. The Boundary Layer options provided are County, Agricultural Statistics Districts (ASD), State, and Region. </li> <li>National Cultivated Layer -- based on the most recent five years (2013-2020).</li> <li>National Frequency Layer -- the 2017 Crop Frequency Layer identifies crop specific planting frequency and are based on land cover information derived from the 2008 through 2020CDL's. There are currently four individual crop frequency data layers that represent four major crops: corn, cotton, soybeans, and wheat.</li> <li>National Confidence Layer -- the Confidence Layer spatially represents the predicted confidence that is associated with that output pixel, based upon the rule(s) that were used to classify it. Western/Eastern/Central U.S.</li> </ul> <p>Visit <a href="https://nassgeodata.gmu.edu/CropScape/">https://nassgeodata.gmu.edu/CropScape/</a> for the interactive map including tutorials and basic instructions. These options include a "Demo Video", "Help", "Developer Guide", and "FAQ".</p></li></ul><p></p>
