Abstract:
GDA CropID 2023 South America map is a GIS raster format product with 250-meter spatial resolution. This is the final map for the 2023 season in South America. It incorporates the results of the first mapping done during the 1st harvest (safra) season. The map covers the five major soybean-producing countries in South America, which consists of Brazil, Argentina, Paraguay, Bolivia, and Uruguay. It offers 2023 corn and soybean locations for select seasons. Locations for 2023 soybeans (1st season) are available for Brazil, Argentina, Paraguay, Bolivia, and Uruguay. Locations for 2023 soybeans (2nd season) are available for Argentina, Paraguay, Uruguay, and the state of Parana in Brazil. Corn (2nd season) locations are available for Brazil, Paraguay, and the department of Santa Cruz in Bolivia. Additionally, corn locations are available for Argentina and Uruguay. Double-cropped locations for the crops listed above are presented as separate classes on the map. Please see the “Classification Categories” section for further details. The map is based on the deep time series analysis of optical satellite imagery.

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 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 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.
