Abstract:
GDA CropID 2023 Brazil map is a GIS raster format product with 250-meter spatial resolution. The map offers various land cover classes for the entire Brazil, including 2023 soybean, corn (2nd harvest), corn (3rd harvest), and cotton locations. Cotton is only available for the states of Bahia, Mato Grosso, Mato Grosso do Sul, and Rondônia. Double-cropped fields covering the safra and safrinha seasons are specified. For a complete list of classes, see the “Classification Categories” section.

2023 refers to the crop harvest year.

GDA CropID maps utilize time series of GDA GeoChronicles™ imagery coverages. GDA GeoChronicles™ are global deep time series of 10-day, 10-meter analysis ready optical satellite imagery coverages produced by GDA Corp by fusing Copernicus Sentinel-2A and Sentinel-2B imagery and NASA / USGS Landsat 8 and Landsat 9 imagery.

GDA uses deep time series of GeoChronicles™ composites to identify crop type and land cover locations during each given season.

The CropID product is produced by GDA Corp for USDA Foreign Agricultural Service (USDA FAS) under a Small Business Innovative Research (SBIR) contract with the USDA/FAS/GMA/IPAD.

The 250-meter CropID product was originally produced at 10-meter spatial resolution. The final 10-meter crop mask was resampled to 250-meters for use on the USDA/NASA Global Agricultural Monitoring (GLAM) system at https://glam1.gsfc.nasa.gov/.
