A satellite map of vegetation for the U.S.
| Many people are interested in the condition of the major crop-producing areas in the U.S. and need a way to quickly monitor crop progress, condition, and state of development. The GreenReport is a set of four maps produced from satellite data that illustrate crop and vegetation conditions throughout the United States on a weekly basis. It uses the Normalized Difference Vegetation Index (NDVI), which measures the amount of green plant material that is actively growing. In this image from mid-July 2000, dark green colors indicate areas containing abundant vegetation, while brown areas indicate sparse vegetation. The map highlights actively growing vegetation in the nation's primary crop producing regions (circled), where the main crops are: spring wheat (1), corn and soybeans (2 and 4), and corn, milo, soybeans, and wheat (4). This map, together with the other maps in the GreenReport series, can provide farmers and crop producers with information that will help them make important decisions about managing their crops. |
