These new Cropland Data Layer products, which are derived from satellite image observations at 30-meter (0.22 acres per pixel) resolution, help users visualize U. S. crop planted area during the last calendar year. Three earth observing satellites were used for the production of this product, including; the newly launched Landsat 8, and Disaster Monitoring Constellation’s Deimos-1 and UK2.
NASS developed CropScape in cooperation with the Center for Spatial Information Science and Systems at George Mason University in Fairfax, Va. This tool is available online.
Safeguarding freshwater resources is crucial, and while scientists use a variety of ground-based techniques to gauge water quality, the Landsat program has provided water quality data from orbit for decades.
