To meet it, they turned to the joint NASA - U.S. Geological Survey’s Landsat 8 satellite to fill in the missing pieces
“During abnormal growing seasons or natural disasters, satellites shine,” said Rick Mueller, Head of USDA’s National Agricultural Statistics Service, or NASS Spatial Analysis Research Section and manager of the Cropland Data Layer Program in Washington. “Landsat is a robust and independent way to validate what our statistics are telling us.”
