The Cropland Data Layer (CDL) contains crop specific digital data layers, suitable for use in geographic information systems (GIS) applications.  The CDL Program annually focuses on the corn/soybean/rice/cotton agricultural regions in the Midwestern and Mississippi Delta States with the focus of producing digital categorized geo-referenced output products using imagery from the ResourceSat-1 AWiFS sensor.  See the Indian Government's National Remote Sensing Agency handbook for the Resourcesat-1 satellite. The CDL Program represents a cooperative venture between three USDA Agencies (Headquarters units of NASS, the Foreign Agriculture Service IPA group and the Farm Service Agency/Aerial Photography Field Office) plus in-state agreements between NASS Field Offices and their respective state government or university partners. Currently there are numerous historical research reports with more detailed information on NASS's general uses of remote sensing and GIS.

The Cropland Data Layer product contains statewide categorizations of ortho-rectified mosaicked images using See5 software, and are exported to GeoTIFF format.  ESRI’s ArcReader thin-client browser can be downloaded to view the CDL's. Limitations of this data are declared.  The CD-ROM's and/or DVD’s are at cost of reproduction to the public.  

Visit our cooperators sites to see how they are using and enhancing the Cropland Data Layer products.
