The Cropland Data Layer in The Cropland Data Layer in MississippiMississippi
• Based on USDA/NASS programs started in the 1970s and the LARSYS software from Purdue University.
• Mississippi project started in 1999 using the Peditor and RSP software programs of NASS
• A cooperative project of NASS, Mississippi State University, and the Mississippi Department of Agriculture and Commerce
Data Collection for the MS 2004 Data Collection for the MS 2004 Cropland Data LayerCropland Data Layer
• June Agricultural Survey Area Frame sample selection of 356 segments by strata, generally 1 square mile per segment.
• June Agricultural Survey field observations.
• Landsat 5 satellite imagery scenes with little or no clouds.

Multi-Temporal Crop SignaturesMulti-Temporal Crop Signatures
• Computer processing using Peditor and RSP.
• Use of two Landsat 5 scenes of different dates with 7 bands each.
• Use of the ground truth data.
• Clustering the crop signatures and training the classifier. • Comparison of statistics of 3 possible analysis districts to
select the best classification for the MS Delta.

Multi-Temporal StrategiesMulti-Temporal Strategies
•Three multi-temporal strategies were tested for the MS Delta region.
•The date combination selected for the multi-temporal administrative district gave superior definition for the classified map and better classification statistics overall.

Acreage EstimatesAcreage Estimates
•The 2004 CDL acreage estimates for the major crops were consistent with previous years with 2 crops essentially in agreement with the NASS Official Estimates.
•Very early (wheat and corn) and late (sweet potatoes) crops showed less agreement, indicating the importance of the satellite scene dates.
