The U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS) has announced the release of new satellite images depicting agricultural land cover across most of the nation for the 2009 crop year. The images, referred to as cropland data layers (CDL), are a useful tool for monitoring crop rotation patterns, land use changes, water resources and carbon emissions. These crop-specific, digital data layers are suitable for use in geographic information systems (GIS) applications. They can be used by agribusinesses, farmers, government agencies, researchers and academic institutions to study pesticide risk, epidemiology, transportation, fertilizer usage, carbon dioxide flux and other topics. The entire inventory of CDL products, including metadata and accuracy assessments, is available online at the USDA National Resource Conservation Service’s Geospatial Data Gateway: http://datagateway.nrcs.usda.gov and at this NASS Web site: http://www.nass.usda.gov/research/Cropland/SARS1a.htm. |
