Summary: Every year, the USDA’s National Agricultural Statistics Service (NASS) uses data from satellites like Landsat to estimate crop types and crop yields in the United States. The result is the Cropland Data Layer (CDL), which offers an annual look at more than 100 crop categories across the country. In this episode, Dave Johnson with NASS discusses how Landsat can identify different crops, providing a valuable economic tool for agriculture.
