Abstract:
GDA CropID 2022 Brazil map is a GIS raster format product with 250-meter spatial resolution. The map covers the entire Brazil. It offers 1 crop type class, including 2022 corn (2nd season) locations. The map is based on the deep time series analysis of optical satellite imagery.

2022 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 from Copernicus Sentinel-2A / 2B and Landsat 8 / 9 imagery.
