The U.S. Geological Survey’s Landsat group has announced that the six-millionth free Landsat scene has been downloaded from the USGS archive. USGS made Landsat data available for no cost starting in October 2008 (with free Landsat 7 data). Then, in January 2009 Landsat 1–5 data were also made available at no cost. Since then, USGS has experienced a 60-fold increase in daily data downloads. Free Landsat data together with today’s powerful computer processing capabilities have enabled large-scale land use studies that in the past were too costly to be conducted by all but a few institutions—what some are calling a “democratization of satellite mapping.”

Satellites offer a wealth of information pertinent for water and food security. Landsat has long been a foundational piece of the “Space for Ag” initiative.
