Crop Statistics

Pixel counting is usually downward biased when compared to official estimates. Counting pixels and multiplying by the area of each pixel will result in biased area estimates and should be considered raw numbers needing bias correction. Official crop acreage estimates are available at http://www.nass.usda.gov/

NASS Cropland Data Layer Applications

http://nassgeodata.gmu.edu/CropScape

• Operational Program– Timely estimate delivery– Measureable statistical error– Set national/regional/county acreage estimates

• Components– DMC/Landsat imagery– Farm Service Agency/Common Land Unit– USGS NLCD/ancillary layers– June Agricultural Survey

• Leverage– CDL program paramount to other NASS geospatial activities– Partnerships with cooperating agencies critical for success– Heavy reliance on satellites and information technology

• Distribution– CropScape Portal– NRCS Data Gateway
